Fault tracing
165
MOD CHOKE T
(FF89)
02.17 AW 3 bit 13
Overtemperature in choke of liquid cooled R8i
inverter module.
Check inverter fan.
Check ambient temperature.
Check liquid cooling system.
MOT CUR LIM
(2300)
Drive limits motor current according to current
limit defined by parameter 20.03.
Reduce load or increase ramp time.
Increase parameter 20.03 value.
Check Fault Function parameters.
MOTOR STALL
(7121)
02.16 AW 2 bit 09
(programmable
Fault Function
30.10)
Motor is operating in stall region due to e.g.
excessive load or insufficient motor power.
Check motor load and drive ratings.
Check Fault Function parameters.
MOTOR STARTS
(FF34)
Motor Identification Run starts. This warning
belongs to ID Run procedure.
Wait until drive indicates that motor
identification is completed.
MOTOR TEMP
(4310)
02.15 AW 1 bit 03
(programmable
Fault Function
30.04…30.09)
Motor temperature is too high (or appears to be
too high) due to excessive load, insufficient
motor power, inadequate cooling or incorrect
start-up data.
Check motor ratings, load and cooling.
Check start-up data.
Check Fault Function parameters.
MOTOR 1 TEMP
(4312)
Measured motor temperature has exceeded
alarm limit set by parameter 35.02.
Check value of alarm limit.
Check that actual number of sensors
corresponds to value set by parameter.
Let motor cool down. Ensure proper motor
cooling: Check cooling fan, clean cooling
surfaces, etc.
MOTOR 2 TEMP
(4313)
Measured motor temperature has exceeded
alarm limit set by parameter 35.05.
Check value of alarm limit.
Check that actual number of sensors
corresponds to value set by parameter.
Let motor cool down. Ensure proper motor
cooling: Check cooling fan, clean cooling
surfaces, etc.
MOT POW LIM
(FF86)
Drive limits motor power according to limits
defined by parameters 20.11 and 20.12.
Informative alarm
Check parameter 20.11 and 20.12 settings.
Check Fault Function parameters.
MOT TORQ LIM
(FF85)
Drive limits motor torque according to
calculated motor pull-out torque limit and
minimum and maximum torque limits defined
by parameters 20.13 and 20.14.
Informative alarm
Check parameter 20.13
and 20.14 settings.
PANEL LOSS
(5300)
Control panel selected as active control
location for drive has ceased communicating.
Check panel connection (see appropriate
hardware manual).
Check control panel connector.
Replace control panel in mounting platform.
Check Fault Function parameters.
