Leadshine two-phase stepper motor driver M860 20-80VDC power supply

 

 

The M860 Stepper Motor Drivers is a excellent performance microstepping based on pure-sine current control.With above technology and the self-adjustment function(self-adjust current control) to various motors, keep the driven motors run with low noise,less heating, smoother movement and better performances at higher speed than other drives in the markets.it is adapt to driving 2,3,4 phases hybrid stepper motors.

M860 Stepper Motor Driver’s Microstep and Current

The drives uses an 8 bits DIP switch to set stepper motor resolution and motor operating current, as shown below:

M860 Stepper Motor Driver’sMicrostep Resolution Selection

Microstep resolution is set by SW5, SW6, SW7, SW8 of the DIP switch as show in following:

M860 Stepper Motor Driver’sCurrent Settings

 

The first three bits (SW1, SW2, SW3) of the DIP switch are used to set the dynamic current. Select a setting that closest to your motor's required current.

Note:Due to motor inductance, the actual current in the coil may be smaller than the dynamic current setting, particularly in high speed condition.
