9. o supply the driver However unregulated power supplies are preferred due to their ability to withstand current surge If regulated power supplies such as most switching supplies are indeed used it is important to have large current output rating to avoid problems like current clamp On the other hand if unregulated supply is used one may use a power supply of lower current rating than that of motor typically 50 70 of motor current The reason is that the driver draws current from the power supply capacitor of the unregulated supply only during the ON duration but not during the OFF duration Therefore the average current withdrawn from power supply is considerably less than motor current Multiple Drivers It is recommended to have multiple drivers to share one power supply to reduce cost if the supply has enough capacity To avoid cross interference DO NOT daisy chain the power supply input pins of the drivers Instead please connect them to power supply separately 6 Troubleshooting 1 The status on light s indication RUN green normal work light ERROR red failure light the motor with phase short circuit overvoltage and undervoltage protection NOTE TO CHECK IF DRIVE IS OK NOT OK CONNECT ONLY SUPPLY AC DC VOLTAGE AND GROUND TO THE MICROSTEP DRIVE AND CHECK THE LED INDICATOR IF IT SHOWS GREEN THEN DRIVE IS OK AND IF THE LED INDICATOR SHOWS RED THEN DRIVE IS NOT OK THIS TEST SHOULD BE DONE WHEN THE BELOW TROUBLES I
