6 2 Phase Stepper Motor Drive Status/cause Green lamp Red lamp At power-on Normal Not reliably connected to the motor The motor may be damaged Overvoltage Under-voltage In operation Normal Over-current phenomenon occurs The motor may be damaged Overvoltage Under-voltage Over-temperature Precautions: It is not allowed to connect the stepper motor driver with the power supply and turn on the power swith before the stepper motor driver is not connected with the motor. It is also not allowed to connect the positive and negative ports of the power supply inversely, otherwise the red lamp of the stepper motor driver will be on the stepper motor driver will be damaged!

7 2 Phase Stepper Motor Drive For the two-phase stepper motor driver, the peak current outputted by the output driver is setting through rotating dial switches. Under normal circumstances, the current shall be set as the motor rated current or the current less than the motor rated current, which will be determined according to the customer demand for output torque and motor heating value. If the demand for torque is large, the current shall be set relatively small. If the demand for heating value is small, the current shall be set relatively small.
