The MA860 can accept differential and single-ended inputs (including open-collector and PNP +12V or +24V used. The same as DIR and ENA signals. output). The MA860 has 3 optically isolated logic inputs which are located on connector P1 to accept DIR signal: In single-pulse mode, this signal has low/high voltage levels, line driver control signals. -
Page 5: Connecting The Motor
5. Connecting the Motor motors should be run at only 70% of their rated current to prevent over heating. The MA860 can drive any 2-pahse and 4-pahse 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. -
Page 6: Parallel Connections
This driver uses an 8-bit DIP switch to set microstep resolution, and motor operating current, as shown below: The MA860 can match medium and small size stepping motors (from Nema size 17 to 43) made by Leadshine or other motor manufactures around the world. To achieve good driving performances, it is important to select supply voltage and output current properly. -
