1. Safety and application instructions for VECTOR 54 1.1. General As long as any electrical equipment and machinery is switched on, the operator may touch voltage leading and non-isolated conductors or rotating parts as well as hot surfaces. At removing the covers and the prescribed protections, in handling the machine improperly, or during service work or improper use, there is the danger of death or severe injuries or material damage. All works with transport, installation and commissioning as well as maintenance have to be done by properly trained personnel (regard IEC 364 res. CENELEC HD 384 or DIN VDE 0100 and IEC report 664 or DIN VDE 0110 and national accident prevention regulations or VGB 4). Qualified personnel in terms of these basic security considerations are persons that are used to installation; assembly, commissioning and operation of the product and that have qualifications according to their work (defined in IEC 364 or DIN VDE 0105). 1.2. Intended Usage Frequency Inverters are components for installation within machines that are operated in industrial plants. The commissioning of the frequency Inverter is prohibited until it is ascertained that the machine that includes the frequency Inverters follows the restrictions of the EU directive 2006/42/EG (machine directive). The frequency Inverters match the protection goals of the low voltage directive 72006/95/EG and the harmonized norms of the series EN 50178/ DIN VDE 0160 in connection with EN 60439-1/ DIN VDE 0660 part 500 and EN 601146/ DIN VDE 0558. The operation is only permitted according to the EMC directive (04/108/EG). The technical data and information to connection conditions are to be found on the rating plate or the documentation and have to be completely fulfilled. 1.3. Transport and Storage The considerations for transport, storage and the appropriate handling must be regarded. Damages recognized after delivery must be immediately announced to the transport company. If applicable, notify the distributor before commissioning. Regard the environmental conditions according to prEN 50178.

1.4. Installation The installation and cooling of the device must be in accordance with the provisions of the relevant documentation. The frequency Inverters must be protected from excessive strain. They are to handle only in a way, so that no components are bent and / or isolating distances altered. The contact of electronic components and terminals must be avoided. Frequency Inverters contain electrostatic sensitive devices. These components can be easily destroyed by improper handling. Built-in electrical components must not be destroyed (potential health hazard). 1.5. Electrical connection At working at current Inverters with supplied power regard the valid national accident prevention regulations (e.g. VGB 4). The electrical installation has to be done according to the valid directives (e.g. cable diameters, fuse protection, ground wire connection). More detailed information is to be found in the documentation. Compliance with the limits for the plant according to the EMC juridical directive is in responsibility of the manufacturer of the plant. Considerations for the EMC-compatible installation like screening, grounding, alignment of filters and lying of cables are to be found in the documentation of the frequency Inverters. 1.6. Operation Plants that contain frequency Inverters have to be provided, if applicable, with additional observation and security installations according to the concerning valid security directives, e.g. act on technical work equipment, accident prevention regulations etc. The documentation of the manufacturer has to be regarded. After disconnection of the frequency Inverters from the supply voltage, voltage conducting device parts and cable conductors must not be immediately touched because of possibly charged condensers. Please regard the according notification signs at the frequency Inverters. During operation all covers must kept closed. 1.7. Maintenance and servicing The documentation of the manufacturer has to be regarded.

1.8. Safety and Installation considerations Frequency Inverters from MSF-Vathauer Antriebstechnik are operating resources for the deployment in industrial high-voltage plants and are operated with voltages that may cause heavy injuries or death when touching! • Installations and works may only be executed by qualified electrical trained personnel and at voltage free device. The user manual has to be available at any time and has to be consequently regarded. • The local directives for building electrical plants and accident prevention regulations must be fulfilled. The device is up to 5 minutes after disconnecting from the voltage conducted with dangerous voltage. Due to this, opening of the device or removing the cover res. the I/O module and the display device is only permitted 5 minutes after disconnecting the device from voltage. Before turning the mains voltage on all covers must be mounted again. • Also at motor standstill (e.g. due to electronics lock, short circuit at the output clamps or blocked drive) the voltage circuit clamps, motor clamps and clamps for the brake resistance may conduct dangerous voltage. A motor standstill is not identical with a galvanic disconnection from the mains voltage. • Attention: The Inverter may, depending on the settings, start automatically after powering the mains voltage. Attention! Danger to Life! The power supply conducts voltage under certain circumstances for up to 5 minutes after turning off the mains voltage. Inverter clamps, drive cables and drive clamps may conduct voltage! Touching open or free clamps, cables and device parts may cause heavy injuries or death! Attention • Children and the public must not have access to the device! • The device may only be used for the purpose intended by the manufacturer. Unauthorized changes and the use of replacement parts and additional devices that are not sold or approved by the manufacturer may cause fire, electric shocks and injuries. • Keep the manual in reach and make it available for every user! European EMC directive If the vector field power is installed according to the recommendations of this manual it fulfills the requirements of the EMC directive according to the EMC product norm for motor driven systems EN 61800-3

2. Assembly and Installation 2.1. Installation The devices require adequate ventilation. The hot air has to be dissipated above the Inverter! 2.2. Cabling directives of superior controls The frequency Inverters are developed for the operation in industrial environments where high values of electromagnetic interferences are expected. In general, a professional installation ensures a risk less and error-free operation. If limits are required that exceed the EMC directive limits, the following directives are recommended. 1. Please make sure that all devices in the control cabinet are connected together at a shared grounding point or rail with short cores and great diameter are properly grounded. It is especially important that every control device connected to the inverters (e.g. automation devices) are connected via a short core with high diameter at the same grounding point like the inverter. 2. The PE conductor of the drive controlled by the Inverter should preferably directly connected to the ground connection connected with the heat sink together with the PE of the power supply of the concerning inverter. The existence of a central grounding rail within the control cabinet and the connection of all ground cables to this rail normally guarantees an error-free operation. 3. As far as possible you should use screened cables for the control. The cable ends have to be terminated carefully and it must be taken care that the cores are not unscreened over long distances. The screen of analogue set point cables should only be grounded at the frequency Inverter single-sided. Not used cores of the control cores should be grounded. 4. The control cores have to be laid in the most possible distance from the load cores using separated cable trenches etc. Cable crosses should possibly get an ankle of 90°. 5. Make sure that contactors and relays in the control cabinets are suppressed either by RC connection or varistors in case of AC contactors or by „ free wheeling diodes“ at DC contactors, wherein the interference suppression bust be attached to the coils. The suppression is especially important if the contactors are controlled by the relay in the frequency Inverter (optional). 6. Use screened cores for the load connections and ground the screening at both ends, if possible directly at the PE output of the Inverter. 7. If the drive should run within an environment sensible to electro-magnetic interference, the usage of interference filters is recommended to reduce the gridbound and radiated interferences of the Inverter. In this case install the filter as near as possible to the inverter and take care for grounding. 8. Choose the lowest possible toggle frequency. This minimizes the intensity of the electro-magnetic interference created by the frequency Inverter.
At installation of the Inverters you must not disregard safety directives!

User Manual Frequency Inverter Vector 54 1ph 2.3. Measures to secure the EMC in machinery and plants The following measures are to secure the EMC, which are of absolute necessity to the Inverter technology. The Inverter fulfills the demands of the high noise immunity and the slight-noise emissions for the usage in industries, under the guidelines of this manuals installation consideration. 2.4 Grounding, earthen, potential compensation The correct professional grounding or earthen guarantees the protection of the staff against dangerous touch voltages (input, output and intermediate circuit voltage) and through parasitic current inductance and low-impedance potential compensation an important measure to reduce electromagnetic influences. 2.5. Filtering Filters are inserted into the lead-bound transfer way between the source of interference and the interference suppressor, which is to reduce lead-bound transmissions and to increase the noise immunity. Additional, external filter may have a negative effect on the noise emission! 2.6. Screening signal- and control cables Screening is used for decoupling fields between two spatially separate areas, i.e. is also used to decrease the emission of electromagnetic radiation and to increase the noise immunity. The consistent use of metal cases is one of the most important standard measures to safeguard the EMC. 2.7. Coupling into motor cables The use of twisted core cables can essentially reduce inductive couplings into a circuit. Cable screens must reduce capacitive, inductive and electromagnetic interferences. It is important to note that to reduce low frequency capacitive interference, it is often sufficient to place a one sided screening, whereas inductive and high frequency electromagnetic interference can only be prevented by screening both sides of the cable. The screening must not be used as a protection earthen!!!

3. Technical Features The Vector 54 is a frequency-Inverter with a modulated attachment, which in it’s basic, offers excellent market value for goods by using simple applications. With extra-integrated modules it can be alternated for a controlled drive with vector-control or upgraded to a positioning type. The centerpiece is a 16-bit signal processor with an internal flash for the renewal of the pulse and control-technique-duties. Through a serial- SPI interface the processor is able to communicate with one or more intelligent modules. Under the term of intelligent modules belong the ones which serve the purpose of changing the protocol, such as Interbus-S, Profibus, CAN-Bus, as well as systems which give the frequency- Inverter SPS-functionality with a multitude of interconnected inputs, or a plain-text LC-Display and are able to save parameters inside the module. To the passive modules belong the ones, which give the frequency Inverter extra digital inand outputs, a rotary-encoder-input, and the adaptation to RS 232and RS 485 interface. The modular mount simplifies flexible processing of customer wishes and customer orientated developments. This is the result of years of experience with the demands of the frequency-Inverter for practical use. The menu-surface is clearly arranged and very well structured.
Special functions The practical design offers the following advantages: Different installation positions optimize the installation, and minimize the space requirement in the switch cabinet. Furthermore a braking chopper is integrated in the VECTOR 54 A plug-on type operator interface offers the following advantages: • • •
LC-Graphic display Plain text display On-line parameterization

6. Programmable parameter sets Two independent parameter sets are available for the parameterization, in which the runningup, - running downtimes as well as the min.-and max. rotating field –frequency for the rightand left rotation can be adjusted separately. 6.1. Running up time Time during which the motor would reach the previously set maximum frequency starting at 0 Hz using a ramp set value. An extension of the running-up time arrives by decreasing the running-down-slope, shortenings by increasing the running-down-slope (Hz/s) The quotient: maximum frequency/running-up time yields the so-called ramp. This designates the change of the rotating field frequency change per time unit. A ´steep’ ramp is equivalent to a short running-up time. A’ flat’ ramp is equivalent to a long running-up time. The set running-up times must always be application-specific, taking into account the physical realities resulting there from. Especially short running-up times can influence the motor stability or cause a switch-off of the Inverter due to an excess current. A sensible feeling is also required in the selection of sufficiently long running-up times for large centrifugal masses The running-up times are separately adjustable for clockwise and counterclockwise turnings. 6.2. Running down time Time during which the motor would reach 0 Hz starting at the previously set maximum frequency using a ramp set value of 0 V. An extension of the running-down time derives by decreasing the running down ramp, a shortening arrives by increasing the running down ramp. (Hz/s) Essentially, the explanations given in the section “Running-up times” also apply here. When inappropriate short running-down ramps are selected (especially with large centrifugal masses) over voltages in the intermediate circuit can cause a switch-off of the Inverter. Since in this state of operation, the rotating field frequency applied to the motor is slightly less than the frequency of the motor shaft, energy will be fed back (generator operation) resulting in an inadmissible increase of the intermediate circuit voltage in the Inverter. If the special application does not admit longer running-down times, use a braking chopper to reduce the excessive intermediate circuit voltage. The braking chopper will convert the energy produced in the generator operation into heat losses. The running-down times are separately adjustable for clockwise and counterclockwise turnings.

6.3. Quick stop Time during which the motor would reach 0 Hz starting at the previously set maximum Frequency, by taking away the release. An extension of the running-down time arrives by decreasing the running down ramp, a shortening arrives by increasing the running down ramp. The setting of the ramp is done in parameter sets 1 and 2. 6.4. Motor frequency Input of the frequency in Hz of the connected motor. 6.5. Minimum rotating field frequency The minimum rotating field frequency to be set in advance below which the Inverter should not drop even if the lowest set value is applied to the analogue input. The minimum rotating field frequency is separately adjustable for clockwise and counterclockwise turnings. Attention:
Only a pre-setting of a “min. frequency = 0 Hz” will result in a frequency of 0 Hz with an applied set value of 0 volt. With a set frequency >0 Hz, a frequency of 0 Hz can only be obtained via a STOP frequency.
6.6. Maximum rotating field frequency In advanced set maximum rotating field frequency, which the Inverter should never exceed, even if the highest possible set value (admissible range: 0 V to 10 V) is applied to the analogue input. The maximum rotating field frequency is separately adjustable for clockwise and counterclockwise turnings. 6.7 Digital output (frequency) Set rotating field frequency at which to switch the digital output. This relay function is activated by specifying values other than 0. 6.8 Digital output (current) To be set current level at which the digital output should switch. To activate this relay function, the value entered for the “Digital output” parameter must be of a value which is higher than ZERO.

User Manual Frequency Inverter Vector 54 1ph 6.9. Static Boost Deviating from the linear V/f characteristics, this voltage increase is specified in percent of the nominal voltage to increase the starting torque at low rotating field frequencies. With low rotations, the copper resistance of the stator winding strongly influences the operating characteristics of the motor. Without a voltage correction, the breakdown torque is significantly reduced towards low rotating field frequencies. During slow starts, it could happen that the motor does not start due a too high breakaway torque to be obtained. By using a voltage increase - the so-called BOOST - the starting torque is increased. The amount of the BOOST is specified in percentage of the nominal voltage at 0 Hz. Starting at this value, the voltage is continually raised with an increasing frequency and thus approaches the normal (linear) V/f characteristic: V/f = const. A constantly available voltage increase is called ´static BOOST´. The range of the voltage increase extends to about a frequency of up to of 2/3 of the kink frequency. To prevent a torque jump during the transition of the BOOST to the V/f=constant characteristics, all characteristics of the static BOOST end at the V/f characteristic. Good starting torques is achieved with a BOOST setting of 8%. Exaggerated high values results in an increased motor temperature, which may destroy in the destruction of the motor by, overheat, particularly if no separate fan is used. a high BOOST value can also cause an excessive currant, which will likewise switch the Inverter off.

Dynamic boost
Deviating from the linear V/f characteristics, this “time limit” voltage increase is specified in percent of the nominal voltage for increasing the starting torque at low rotating field frequencies. By using the dynamic boost the motor is exposed to a thermally limited minimal burden. The dynamic boost is added to a static boost, which may exits. The same explanations apply as for the static boost.

User Manual Frequency Inverter Vector 54 1ph 6.11 Time dynamic boost During the running up operations, the dynamic boost is activated for the set duration when the 1Hz is exceeded 6.12. DC brake The value specified in a percentage of the nominal voltage, which determines the stopping torque (torque at standstill) of the motor (“DC brake�). Note:
Despite a high torque generated by the motor at a rotating field frequency of 0 Hz, the motor shaft can slowly be rotated by an externally applied torque, as this is not a regulated system.
6.13 Duration of the DC braking The time for which the DC brake is active. To prevent a thermal overload of the motor, the DC brake is limited to a maximum of 25 seconds, and it is activated when it reaches 0 Hz. DC braking can either be activated by applying a set value of 0 V, or by a STOP command. DC braking remains active for the entire preset time if the set value is not increased again during the braking or a START command is given. Reversing does not activate DC braking. 6.14. Current limit On exceeding of the current limit set in the particular parameter sets the rotary field frequency is reduced to a value, in which the motor current the set current limit no longer exceeds. The reduction can be carried out up to a rotating field frequency of about 8 Hz.

Note: With the exception of 16 kHz, the switching frequency will be noticed as a more or less loud secondary noise. The lower the switching frequency, the lower the switching power losses in the power circuit, the less the Inverter will warm up. The best motor characteristics are achieved from 2 kHz upwards. The switching frequency of 16 kHz should only be used in exceptional cases due to the increased heating of the Inverter. If this is used a sufficient ventilation of the inverter must be guaranteed and the power may have to be reduced.

11. Application notes 11.1. Dynamic braking by means of a braking chopper The built-in braking chopper equipped with an external braking resistor enables dynamic braking of large masses and does not initiate a switch-off of the Inverter. When breaking a centrifugal mass at a relatively short running-down time (brake time), the mass inertia of the entire drive works as a generator torque. This braking operating is equivalent to an energy feedback of the drive resulting in a temporary circuit voltage increase up to the point where the excessive voltage switch-off is initiated. By routing this braking energy into a resistor, the switching off can be prevented. The braking chopper compares the temporary circuit voltage with a reference voltage, which has a voltage level below the over-voltage tripping level. When the reference voltage is exceeded a power transistor connects the braking resistor to the temporary circuit voltage. The resistor then converts the power generated by the motor into a heat loss. The braking power can be calculated as a function of the activation time (ED) of the braking resistors. Thus the breaking chopper can be individually adapted to the drive.

The resistors used must be suited to the current and the peak power. The electric strength of the resistors must be 1000V. The necessary average braking power is calculated from the peak and the operating time of the chopper. Nom. power (W)= operating-time ED (s) * peak power (W) Cycle time (s) The practice showed that for most applications, resistors with a nominal continuous power of 60 Watts are sufficient.

11.2. Motor protection Despite a high-grade sine modulation, additional losses occur in the motor in powering standard 3-phase asynchronous motors. Even at nominal revolutions, these losses require a power reduction the extent on which essentially depends on the exploitation of the temperature limits of the motor. For drives of a square counter-torque (e.g. fans) and 50 Hz as maximum rotating field frequency, the imposed power reduction is usually around 0 - 10%. For drives of a constant counter-torque (compressors, conveyer belts, etc.), the power reduction has to be selected accordingly larger, depending on the range of the adjustment. To guarantee the safe operation of a motor in the adjustment range, the stationary load torque must lie below the continuous operating characteristic of the motor to guarantee a safe operation of a motor. During operation and starting, the drive will momentarily be in a position to submit or corresponding to the current limitation of the Inverter. The setting of the voltage increase (static Boost) essentially determines the maximum torque below 10 Hz. During a continuous operation, an excessive high boost setting for the lower rotating field frequency range (up to 15 Hz) can cause the motor to overheat. A comprehensive thermal protection of the self-cooling motor can be achieved by means of a temperature sensor (e.g. PTC thermistor or thermal time-delay switch) built into the motor. For revolutions above 120% of the nominal speed, the performance of the motor has to be checked.
