Turn OFF power supply before connecting or disconnecting any wiring
Disconnecting the motor with the power ON will destroy the drive board
User instructions
Stepper motor must have four phases and either five, six or eight wires
GSM2 Stepper Motor Drive Board
The GSM2 is a standalone drive board designed to drive a stepper motor in unipolar mode
It is done either with or without forcing resistors connected between motor commons and volts
When using the logic connections, you are able to select full, half or wave mode and direction and speed external clock
The GSM2 drive board allows an enable and disable input for various start/stop control options
The stepper motor used with the board must also have four phases and five, six or eight wires
