DM542 Stepper Motor Controller Leadshine 2-phase Digital Stepper Motor Driver 18-48 VDC Max. 4.2A for 57 86 Series Motor

Regular price ¥55.00 CNY
Regular price ¥60.00 CNY Sale price ¥55.00 CNY


The DM542/DM556 DSP digital driver is powered by DC 24-50V and is suitable for two-phase hybrid stepping motors with a 42-57-86 two-phase hybrid stepping motor and a current less than 4.2A. The current loop of the AC servo drive is used for subdivision control, which has strong anti-interference, stable operation of the equipment, no loss of step, low torque fluctuation of the motor and high positioning accuracy.

Drive function description signal interface:

PUL+ and PUL- are the positive and negative terminals of the control pulse signal; DIR+ and DIR- are the positive and negative terminals of the direction signal; ENA+ and ENA- are the positive and negative terminals of the enable signal.

Motor interface

A+ and A- are connected to the positive and negative ends of the A-phase winding of the stepping motor; B+ and B- are connected to the positive and negative ends of the B-phase winding of the stepping motor. When the A and B two-phase windings are exchanged, the motor direction can be reversed.

Power interface

It is powered by DC power supply. The working voltage range is recommended to be 20-50VDC. The power supply is greater than 100W. According to the actual use, the input is not suitable for DC48V.

Indicator light

The drive has two red and green lights. The green light is the power indicator. When the drive is powered on, the green light is always on; the red light is the fault indicator. When an overvoltage or overcurrent fault occurs, the fault light is always on. After the fault is cleared, the red light is off. When the drive fails, the fault can only be cleared by powering up and re-enabling.
