WARNING
Dangerous voltages exist on the drive when it is powered. When possible, disconnect
the AC line voltage from the drive while troubleshooting. Be alert. High voltages can
cause serious or fatal injury.
Perform the following steps before starting any procedure in this section:
Disconnect AC line voltage from the drive.
Check the drive closely for damaged components.
Check that no conductive or other foreign material has become lodged on the printed
circuit board.
Verify that every connection is correct and in good condition.
Verify that there are no short circuits or grounded connections.
Check that the drive’s rated armature output is consistent with the motor rating.
Motor does not run
Check for blown fuses or tripped circuit breaker.
Check that the speed adjust potentiometer is securely connected to S1, S2, and S3. If
an input voltage signal is used, check that the connections to S1 and S2 are secure.
Check that S1 and S2 are not shorted together.
Check that the drive recieves AC power at L1 and L2.
Check that the motor is not jammed or restricted from movement.
Check that the drive is not in current limit. Recalibrate the CURRENT LIMIT trimpot if it
is set too low (see page 14 for recommended trimpot settings).
