Connecting the Power Supply
If you need information about choosing a power supply, please read “Choosing a Power Supply” located above in
this manual.
Connect the motor power supply “+” terminal to the driver terminal labeled “+”. Connect power supply “-” to the
drive terminal labeled “-”. Use wire in the range of 16 to 20 AWG. The STM23 drives contain an internal fuse that
connects to the power supply + terminal. This fuse is not user replaceable. If you want to install a user serviceable
fuse in your system install a 4 amp fast acting fuse in line with the + power supply lead.
It is important that the motor frame be electrically connected to ground. When the motor is mounted on an insu-
lated surface, a ground wire is required as shown in the diagram below. Also, in applications where multiple STMs
are used on a machine, individual ground wires may reduce the overall electrical noise level.
Be careful not to reverse the wires. Reverse connection may open the internal fuse on your driver and
void your warranty.
