●Two-phase 4-wire / 8-wire: This stepper motor driver can operate 4-wire/8-wire two-phase stepper motor. Over-voltage over-current protection. ●Stable and quiet: The latest 32-bit DSP technology is suitable for driving 57 and 86 series engines. Stable operation and low noise at medium to low speed. can meet the application requirements of most medium-sized companies. And small equipment. ●Precise current control: This DM542 digital stepper motor driver has precise current control that greatly reduces engine heat. ●Strong anti-interference: optical insulation input, which ensures strong anti-interference ability ●Self-optimisation function: Integrated with parameter self-optimisation function, which automatically generates optimal operating parameters for different motors.
