Fault tracing
284
LOAD SP DW LIM
(FFB9)
3.32 CSW bit 6
The speed reference is limited in the reverse
direction according to the Load speed control
function. Check motor current settings and group 77
settings.
MACRO CHANGE
(FF69) Macro is restoring or user macro is being
saved. Wait until drive has finished task.
MASTERLIM/FLT
(FFB2) Master drive has gone into a fault or has hit
any of the limits. This message is displayed in
the Follower drives only See Master drive for more detailed description
of fault of limit.
MOT CUR LIM
(2300)
3.18 AW 5 bit 10
(programmable
Fault Function
30.23 )
Drive limits motor current according to current
limit defined with parameter
20.03 MAXIMUM
CURRENT.
Reduce load or increase ramp time.
Increase parameter
20.03 MAXIMUM
CURRENT value.
Check Fault Function parameters.
MOTOR STALL
(7121)
3.09 AW 2 bit 9
(programmable
Fault Function
30.10 )
Motor is operating in stall region due to, for
example, 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)
3.08 AW 1 bit 3
(programmable
Fault Function
30.04 … 30.09 )

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.

(4312)
3.16 AW 4 bit 1
Measured motor temperature has exceeded
alarm limit set with parameter
35.02 .
Check value of alarm limit.
Check that actual number of sensors
corresponds to value set with parameter.
Let motor cool down. Ensure proper motor
cooling: Check cooling fan, clean cooling
surfaces, etc.
MOTOR 2 TEMP
(4313)
3.16 AW 4 bit 2
Measured motor temperature has exceeded
alarm limit set with parameter
35.05 .
Check value of alarm limit.
Check that actual number of sensors
corresponds to value set with parameter.
Let motor cool down. Ensure proper motor
cooling: Check cooling fan, clean cooling
surfaces, etc.
