Cause
The condition "I_act = 0 and Uq_set_1
longer than 16 ms at its limit" is present
and can be caused by the following:
Motor not connected or motor contac-
•
tor open.
No DC link voltage present.
•
Motor Module defective.
•
The specified flux setpoint cannot be
reached although 90% of the maximum
current has been specified.
Incorrect motor data.
•
Motor data and motor configuration do
•
not match.
The current limit has been set too low
•
for the motor.
Induction motor (encoderless, open-
•
loop controlled) in I t limiting.
2
An incorrect commutation angle was de-
tected that can result in a positive coupling
in the speed controller.
Possible causes:
The motor encoder is incorrectly ad-
•
justed with respect to the magnet posi-
tion.
The motor encoder is damaged.
•
Data to calculate the motor model has
•
been incorrectly set.
Pole position identification might have
•
calculated an incorrect value when ac-
tivated.
The motor encoder speed signal is
•
faulted.
The control loop is instable due to
•
incorrect parameterization.
The encoder was replaced.
•
A third-party, build-in or linear motor
•
was re-commissioned.
The motor with integrated and adjusted
•
encoder was replaced.
The firmware was updated to a version
•
that checks the encoder serial number.
Remedy
Connect the motor or check the motor
•
contactor.
Check the DC link voltage.
•
Check the Motor Module.
•
Correct the motor data.
•
Check the motor configuration.
•
Reduce the induction motor load.
•
If the encoder mounting was changed, re-
•
adjust the encoder.
Replace the defective motor encoder.
•
Correctly set the motor stator resistance,
•
cable resistance and motor-stator leakage
inductance.
Calculate the cable resistance from the
cross-section and length, check the induct-
ance and stator resistance using the motor
data sheet, measure the stator resistance,
e.g. using a multimeter - and if required,
again identify the values using the station-
ary motor data identification.
With pole position identification activated,
•
check the procedure for pole position iden-
tification and force a new pole position
identification procedure by means of de-
selection followed by selection.
For the first two causes:
Carry out an automatic adjustment using the
pole position identification routine.
Acknowledge the fault. Initiate the pole position
identification routine. Then check that the pole
position identification routine is correctly exe-
cuted.
SERVO:
If a pole position identification technique is
selected, and if p0301 does not contain a mo-
tor type with an encoder adjusted in the facto-
ry, then p1990 is automatically activated.
Mechanically adjust the encoder. Accept the
new serial number.
For the last two causes:
Accept the new serial number with p0440 = 1.
