The DM542 stepper drive is designed to power 2 phase(1.8°) or 4-phase(0.9°) NEMA17, 23 and 24 hybrid stepper motors. It can be adopted in many industries(CNC machinery, electronics, medical, automation, packaging…) for applications such as CNC routers, mills, plasma, laser cutters, factory assembly lines, vending machines, etc.
 
Key Features:
Fault and Brake output
CE certified and RoHS compliant
