DC motor drive DM542 series

hybrid stepper2-phase

Descriptions DM542 is a type of two-phase hybrid stepping motor driver, The drive voltage of which is from 24VDC 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 running smoothly almost without noise and vibration. Holding torque when DM542 driver runs 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, Computer embroider machine, packing machines and so on. Features 1. Average current control, 2-phase sinusoidal output current drive 2. Supply voltage from 18VDC to 50VDC 3. Opto-isolated signal I/O 4. Overvoltage, under voltage, over-current, phase short circuit protection 5. 15 channels subdivision and automatic idle-current reduction 6. 8 channels output phase current setting 7. Offline command input terminal 8. Motor torque is related with speed, but not to step/revolution 9. High start speed 10. High holding torque under high speed
