Stepper driver 2-phase 2M420 - details see: https://www.machineto.com/stepper-driver-2-phase-2m420-10239114

Stepper driver 2-phase 2M420

1. The maximum supply voltage reaches 40V
2.A dedicated control chip is used
3.Offline function
4.Optical coupling devices

Features:
1. The maximum supply voltage can reach 40V, which can provide better dynamic drive performance;
2. The bipolar constant current drive mode is taken with a maximum drive current up to 2.5A per phase, which can drive any two-phase bipolar hybrid stepper motors with a current less than 2.5A;
3. The drive output phase current of a motor can be regulated through the DIP switch, to match motors of different specifications;
4. 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;
5. 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;
6. Supporting offline function, so that the output current of a motor can be cut off if necessary;
7. Optical coupling devices are used for the isolation of the input circuit of the control signals to reduce interference of external noises.
