Quick Details

  • Brand Name: LONGS
  • Model Number: DM542A
  • Certification: CCC,CE,ROHS
  • Type: STEPPER MOTOR DRIVER

Specifications

  DM542A is a type of two-phase hybrid stepping motor driver, The drive voltage of which is from 18VDC to 50VDC. It is designed for use with 2-phase hybrid stepper motor of all kinds with 42mm to 86mm outside diameter and less than 4.0A phase current. This circuit that it adopts is similar to the circuit of servo control which enables the motor run smoothly almost without noise and vibration. Hording torque when DM542A run under high speed is also significantly higher than the other two-phase driver, what's more, the positioning accuracy is also higher. It is widely used in middle and big size numerical control devices such as curving machine, CNC machine, and computer embroider machine, packing machines and so on.

Features:

lHigh performance, low price

lAverage current control, 2-phase sinusoidal output current drive

lSupply voltage from 18VDC to 50VDC

lOpto-isolated signal I/O

lOvervoltage, under voltage, overcorrect, phase short circuit protection

l15 channels subdivision and automatic idle-current reduction

l8 channels output phase current setting

lOffline command input terminal

lMotor torque is related with speed, but not related with step/revolution

lHigh start speed

lHigh hording torque under high speed
