Manual of 2-phase hybrid stepper motor driver DM542
DM542 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 DM542 run under high speed is also significantly higher than the other two-phase driver, what is 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.

The first three bits (SW 1, 2, 3)of the DIP switch are used to set the dynamic current. Select a setting
Closest to your motor is required current
Output current (A)
4) Semi-flow function:
Semi-flow function is that there is not step pulse after 500 ms, the driver output current automatically reduced to 70% of rated output current, which is used to prevent motor heat.
4. Power connections
(1)+ v ,GND:Power Supply.
+V: Power supply, 16~50 VDC, Including voltage fluctuation and EMF voltage. The max current is 5A.
(2) A+ A- B+ B-:Connecting 2 phase stepper motors.
The driver & 2-phase hybrid stepping motor use four-wire connection, the motor can be connected in parallel & series bipolar. As for bipolar connection, it is higher performance with high-speed, but the current of driver is larger (it is 1.73 times more than the motor winding current).
Connecting in series, the driver \'s current is equal to the motor winding one.
