LEESON Chassis Mount Regenerative Control: 175721.00 - Manual (Page 49)

Troubleshooting
Check the following steps before proceeding
1. The AC line voltage must match the voltage on the drive
nameplate.
2. On dual voltage drives, check that the voltage switches are
set to the correct position.
3. The deadband (DB) must be set approximately at the 3
o’clock position for 60 Hz AC line frequency or at 9 o’clock
for 50 Hz AC line frequency.
4. The motor must be rated for the drive’s rated armature (all
motors) and field outputs (shunt wound motors only).
5. Do not make any connections to F1 and F2 if using a
permanent magnet motor.
6. Terminal block connections should be consistent with the
connections shown in this manual.
7. Check that line fuse FU501 (and FU502 for 230 VAC input)
is properly sized and not blown.
Warning
Dangerous voltages exist on the drive when it is powered.
When possible, disconnect the drive while troubleshooting.
High voltages can cause serious or fatal injury.
