Stepmotor driver SMD-4.2

SMD-4.2 is a stepper driver, designed by our company for 2 and 4-phases stepmotors with current per phase up to 4.2A. Driver provides microstepping and current reduction in holding mode.

Standard logic signals STEP and DIR are used for motion control. Enable signal is also provided. SMD-4.2 operates with external logic signals source – frequency generator, PLC, computer's LPT-port and etc.

The main parameters of stepmotor driver SMD-4.2

  • Max. current per phase - 4.2Amp
  • Power supply - 12-48VDC
  • Microstepping mode - 1, 1/2, 1/4, 1/16
