Figure 7 4-lead Motor Connections 6. Power Supply Selection The DM556T can power medium and large size stepping motors (frame size from NEMA 23 to 24). To get good driving performances, it is important to select supply voltage and output current properly. Generally speaking, supply voltage determines the high speed performance of the motor, while output current determines the output torque of the driven motor (particularly at lower speed). -

DM556T Digital Stepper Drive User Manual Time(s) of Priority Sequence wave of red LED Description Blink Over-current protection activated when peak current exceeds the limit. Over-voltage protection activated when drive working voltage is greater than 60VDC Reserved. When above protections are active, the motor shaft will be free or the red LED blinks. Reset the drive by repowering it to make it function properly after removing above problems.
