4. DIP Switch Setting The DM860N driver uses a 8-bit DIP switch to set operating current, standstill current, and microstep resolution. The detailed description is as follows:... -
Page 9: Standstill Current Setting
Digital Microstep Driver DM860N 4.2 Standstill Current Setting The standstill current can be set with the SW4, OFF means the standstill current is set to about half of the dynamic current (60%), and ON means the standstill current is the same as the operating current. -
Page 10: Power Supply Recommend
The torque is mainly determined by the size of the motor. The large-sized motor has a large torque; the current is mainly related to the inductance, and the small-inductance motor has a high-speed performance, but the current is large. The DM860N can drive Nema 34 two-phase and four-phase hybrid stepper motors. -
