M542 Stepper Motor Driver
stepper motor driver:
 
Introduction:
M542MA is a type  of two-phase hybrid stepping motor driver, the drive voltage of it 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 smiliar to the circuit of servo control which enables the motor run smoothly almost without
noise and vibration. Holding torque when M542MA run under high speed is also significantly
higher than the other two-phase driver, whats 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:
l  High performance, low price
l  Average current control, 2-phase sinusoidal output current drive
l  Supply voltage from 18VDC to 50VDC
l  Opto-isolated signal I/O
l  Overvoltage, under voltage, overcurrent, phase short circuit protection
l  15 channels subdivision and automatic idle-current reduction
l  8 channels output phase current setting
l  Offline command input terminal
l  Motor torque is related to speed, but not related to step/revolution
l  High start speed
l  High hording torque under high speed
