J3), this signal is counter-clock (CCW) pulse，active at high output). The M542 V2.0 has 3 optically isolated logic inputs which are located on connector P1 to level or low level (set by inside jumper J1, J2). For reliable motion response, accept line driver control signals. -

5. Connecting the Motor motors should be run at only 70% of their rated current to prevent over heating. The M542 V2.0 can drive any 2-phase and 4-phase hybrid stepping motors. Connections to 4-lead Motors 4 lead motors are the least flexible but easiest to wire. Speed and torque will depend on winding Figure 7: 6-lead motor full coil (higher torque) connections inductance. -

7. Selecting Microstep Resolution and Driver Output Current The M542 V2.0 can match medium and small size stepping motors (from NEMA frame size 17 to 34) made by Leadshine or other motor manufactures around the world. To achieve good driving This driver uses an 8-bit DIP switch to set microstep resolution, and motor operating current, as performances, it is important to select supply voltage and output current properly. -

Theoretically, this will reduce motor heating to 36% (due to P=I *R) of the original value. - Page 8 M542 V2.0 Microstepping Driver Manual V1.0 M542 V2.0 Microstepping Driver Manual V1.0 10.
