Troubleshooting

ATTENTION:

This equipment is at line voltage when AC power is

applied. Disconnect and lockout all ungrounded conductors of the AC
power line before working on the unit, Failure to observe this
precaution may result in severe bodily injury or loss of life.

Check the following before proceeding:

• The AC line voltage must match the voltage on the drive nameplate.
• On dual voltage drives, check that the voltage switches are set to the

correct position.

• 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.

• The motor must be rated for the drive’s rated armature

(all motors) and field outputs (shunt wound motors only).

• Do not make any connections to F1 and F2 if using a permanent magnet

motor.

• Terminal block connections should be consistent with the connections

shown in this manual.

• Check that line fuse FU501 (and FU502 for 230 VAC line voltage) is

properly sized and not blown.
