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.
Check the following steps before proceeding:
1. The AC line voltage must be balanced, and match the voltage on the
drive nameplate.
2. Check that all switches are set to the correct positions.
3. The deadband (DB) trimpot 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 fuses FU501 and FU502 are properly sized and not
blown.
8. Check that field fuse FU503 is 1.5 A and not blown.
