Symptom Possible cause Test Solution
Motor speed
unstable
Possible incorrect parameter
settings
Check the settings of all motor parameters,
including all motor compensation settings.
For closed-loop operation, check PID
settings.
Check settings in parameter group 1-6*
Analog I/O mode. For closed-loop
operation, check settings in parameter
group 20-0* Feedback.
Motor runs
rough
Possible over-magnetisation Check for incorrect motor settings in all
motor parameters
Check motor settings in parameter groups
1-2* Motor Data, 1-3* Adv Motor Data, and
1-5* Load Indep. Setting..
Motor will not
brake
Possible incorrect settings in
the brake parameters. Possible
too short ramp-down times
Check brake parameters. Check ramp-time
settings
Check parameter group 2-0* DC Brake and
3-0* Reference Limits.
Open power
fuses or circuit
breaker trip
Phase to phase short Motor or panel has a short phase to phase.
Check motor and panel phase for shorts
Eliminate any short circuits detected.
Motor overload Motor is overloaded for the application Perform startup test and verify motor
current is within specifications. If motor
current is exceeding nameplate full load
current, motor may run only with reduced
load. Review the specifications for the
application.
Loose connections Perform pre-startup check for loose
connections
Tighten loose connections.
Mains current
imbalance
greater than
3%
Problem with mains power (See
Alarm 4 Mains phase loss
description)
Rotate input power leads into the
frequency converter 1 position: A to B, B to
C, C to A.
If imbalanced leg follows the wire, it is a
power problem. Check mains power
supply.
Problem with the frequency
converter
Rotate input power leads into the
frequency converter 1 position: A to B, B to
C, C to A.
If imbalance leg stays on same input
terminal, it is a problem with the unit.
Contact the supplier.
Motor current
imbalance
greater than
3%
Problem with motor or motor
wiring
Rotate output motor leads 1 position: U to
V, V to W, W to U.
If imbalanced leg follows the wire, the
problem is in the motor or motor wiring.
Check motor and motor wiring.
Problem with the frequency
converters
Rotate output motor leads 1 position: U to
V, V to W, W to U.
If imbalance leg stays on same output
terminal, it is a problem with the unit.
Contact the supplier.
Frequency
converter
acceleration
problems
Motor data are entered
incorrectly
If warnings or alarms occur, see 7.3 List of
Warnings and Alarms
Check that motor data are entered correctly
Increase the ramp-up time in 3-41 Ramp 1
Ramp Up Time. Increase current limit in
4-18 Current Limit. Increase torque limit in
4-16 Torque Limit Motor Mode.
Frequency
converter
deceleration
problems
Motor data are entered
incorrectly
If warnings or alarms occur, see 7.3 List of
Warnings and Alarms
Check that motor data are entered correctly
Increase the ramp-down time in 3-42 Ramp
1 Ramp Down Time. Enable overvoltage
control in 2-17 Over-voltage Control.
Acoustic noise
or vibration
(e.g. a fan
blade is
making noise
or vibrations
at certain
frequencies)
Resonances, e.g. in the
motor/fan system
Bypass critical frequencies by using
parameters in parameter group 4-6* Speed
Bypass
Check if noise and/or vibration have been
reduced to an acceptable limit.
Turn off over-modulation in 14-03 Overmo-
dulation
Change switching pattern and frequency in
parameter group 14-0* Inverter Switching
Increase Resonance Dampening in
1-64 Resonance Dampening
