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.
