2M412 Stepper Driver

  • Supply voltage: 12 ~ 40V DC
  • Ouput phase current: 0.2 ~ 1.2A
  • Control signal input current: 6~16mA
  • Weight(Net): 0.13kg


The maximum supply voltage can reach 40V;
The bipolar constant current drive mode is taken, with a maximum drive current up to 1.2A per phase, which can drive any 42 series two-phase bipolar hybrid stepper motors with a current less than 1.2A;
The drive output phase current of a motor can be regulated through the DIP switch, to match motors of different specifications;
A DIP switch is used to set the automatic half current function of motors in statically locked status, which can greatly reduce heat dissipation of the motors;
A dedicated control chip is used, with a maximum of 256/200 subdivisions. The subdivision function can be set by the DIP switch, to ensure the best operation stability;
Supporting offline function so that the output current of a motor can be cut off if necessary;
Optical coupling devices are used for the isolation of the input circuit of the control signals to reduce interference of external noises.
