Page 6: Pin Assignment And Description
3 Pin Assignment and Description The MA860C has two connectors, connector P1 for control signals connections, and connector P2 for power and motor connections. The following tables are brief descriptions of the two connectors. More detailed descriptions of the pins and related issues are presented in section 4, 5, 9. -
Page 7: Wiring
4.1 Control Signal Connector (P1) Interface The MA860C can accept differential and single-ended inputs (including open-collector and PNP output). The MA860C has 3 optically isolated logic inputs which are located on connector P1 to accept line drive control signals. These inputs are isolated to minimize or eliminate electrical noises coupled onto the drive control signals. -

Page 9: Power Supply Selection
4.5 Power Supply Selection The MA860C can match medium and small size stepping motors (frame size from NEMA24 to 34) 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. -
Page 10: Selecting Microstep Resolution And Drive Output Current
MA860C Full Digital Stepper Drive Manual V1.0 It is prohibited to pull and plug connector P2 while the drive is powered ON, because there is high current flowing through motor coils (even when motor is at standstill). Pulling or plugging connector P2 with power on will cause extremely high back-EMF voltage surge, which may damage the drive. -

Page 13: Frequently Asked Questions
MA860C Full Digital Stepper Drive Manual V1.0 9 Frequently Asked Questions In the event that your drive doesn’t operate properly, the first step is to identify whether the problem is electrical or mechanical in nature. The next step is to isolate the system component that is causing the problem. As part of this process you may have to disconnect the individual components that make up your system and verify that they operate independently. -
