DMD870 Digital Stepper Drive
User's Manual
Testing the Stepper System
Turn on the power supply, the green (Power) LED will light. The DMD870 has default
parameters stored in the Drive. If the system has no hardware and wirings problem, the
motor should be locked and the Drive should be ready.
If the red LED immediately turns on (flickers), then check power supply, the motor, motor
wirings and try again. Open the tuning software ProTuner and check Drive status by clicking
Err_check. If it's Phase Error, check the motor, motor wirings and try again. If it still doesn't
work after you followed all of the previous steps, please contact our technical team
enquiries@motioncontrolproducts.com
for the support.
If the RED LED is off and the motor is normal, you can start to tune the drive and motor
system with ProTuner. However, we recommend the users to read the following contents
before starting tuning.
