Installation/Connections

Connecting the Power Supply

Connect the power supply “+” terminal to the drive “+” terminal and the power supply “-” terminal to the drive “-” termi-

nal using 16 to 20-gauge wire. The STM17 contains an internal fuse connected to the “+” terminal. This fuse is not user

replaceable. If a user serviceable fuse is desired, install a 2 amp fast acting fuse in line with the “+” power supply lead.

Be careful not to reverse the wires. Reverse connection may open the internal fuse on your driver

and void your warranty.

If a regulated power supply is being used, there may be a problem with regeneration. When a load decelerates rapidly

from a high speed, some of the kinetic energy of the load is transferred back to the power supply, possibly tripping the

over-voltage protection of a regulated power supply, causing it to shut down. This problem can be solved with the use of

an RC-050 regeneration clamp. It is recommended that an RC-050 initially be installed in an application. If the “regen” LED

on the RC-050 never flashes, the clamp is not necessary.
