Stepper Motor Control Modules
Wiring precautions General To ensure the best performance, inputs I0 to I5 are rapid inputs. If the actuator is a dry contact, the inputs must be connected by a twisted pair, or by a shielded cable if the sensor is a two or threewire proximity detector. The module includes as standard basic protection against short circuits or voltage inversions. However, the module cannot remain operational for long with an error. You must therefore ensure that the fuses in series with the supply carry out their protective function. These are 1A maximum fast-blow fuses, the supply energy must be sufficient to ensure their fusion. Important note: wiring of Q0 static outputs The actuator connected to the Q0 brake output has its shared pin connected to supply 0 V. If for any reason there is a 0 V outage of the output amplifier supply (e.g. poor contact or accidental unplugging), when the 0 V of the actuators remains connected to the 0 V supply, there may be enough mA output current from the amplifier to keep low-power actuators triggered.
