product card


Main parameters

Voltage 12 - 24VDC
Max. current per phase 1.3 … 2.8 A
Microstepping 1/1 - 1/256
Control methods STEP/DIR
Size 116x100x23 mm

The driver is intended for small size stepper motors with current per phase up to 2.8 A. The control method is standard STEP/DIR. The driver provides smooth and exact positioning. Holding motor current can be reduced in order to make lower heating and energy save, this function can be switched on or off by a customer.
