Connecting the Power Supply
If you need information about choosing a power supply, please read Choosing a Power Supply located
elsewhere in this manual.
Connect the motor power supply “+” terminal to the drive terminal labeled “VDC”. Connect power supply “-” to the
drive terminal labeled “GND”. Use 18 or 20 gauge wire. The ST 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 servicable fuse in your
system install a fast acting fuse in line with the + power supply lead. Use a 4 amp fuse for the ST5 drives and 7
amps for the ST10.
The green ground screw on the corner of the chassis should be connected to earth ground.
Be careful not to reverse the power supply wires. Reverse connection will
destroy your driver, void your warranty and generally wreck your day.
If you plan to use a regulated power supply you may encounter a problem with regeneration. If you rapidly de-
celerate a load from a high speed, much of the kinetic energy of that load is transferred back to the power supply.
This can trip the overvoltage protection of a switching power supply, causing it to shut down. We offer the RC050
“regeneration clamp” to solve this problem. If in doubt, buy an RC050 for your first installation. If the “regen” LED
on the RC050 never flashes, you don’t need the clamp.
