Operating Instructions, 04/2018, FW V4.7 SP10, A5E34257324B AF
Number Cause
Remedy
F07902
Motor stalled
Check whether the motor data has been set correctly and perform a mo-
tor identification.
Check the current limits (p0640, r0067, r0289). If the current limits are too
low, the drive cannot be magnetized.
Check whether motor cables are disconnected during operation.
A07903
Motor speed deviation
Increase p2163 and/or p2166.
Increase the torque, current and power limits.
F07909
Internal voltage protection: Deacti-
vation only active after POWER
ON
The inverter has activated the "Internal voltage protection" function"
(p1231 = 3). Deactivation of the internal voltage protection (p1231
≠
3)
only becomes active after POWER ON.
A07910
Motor overtemperature
Check the motor load.
Check the motor's ambient temperature.
Check the KTY84 or Pt1000 sensor.
Check the overtemperatures of the thermal model (p0626 ... p0628).
A07920
Torque/speed too low
The torque deviates from the torque/speed envelope curve.
•
Check the connection between the motor and the load.
•
Adapt the parameterization corresponding to the load.
A07921
Torque/speed too high
A07922
Torque/speed out of tolerance
F07923
Torque/speed too low
•
Check the connection between the motor and the load.
•
Adapt the parameterization corresponding to the load.
F07924
Torque/speed too high
A07927
DC braking active
Not required
F7966
Check commutation angle
Carry out pole position identification.
F7969
Pole position identification incorrect An error has occurred during the pole position identification.
Check the following:
•
Motor connection
•
Motor data
A07980
Rotary measurement activated
Not required
A07981
No enabling for rotary measure-
ment
Acknowledge pending faults.
Establish missing enables (see r00002, r0046).
A07991
Motor identification activated
Switch on the motor and identify the motor data.
F08501
Setpoint timeout
•
Check the bus connection.
•
Set the controller into the RUN mode.
•
If the fault occurs repeatedly, check the monitoring time set p2044.
F08502
Monitoring time, sign-of-life expired
•
Check the bus connection.
A08511
Receive configuration data not
valid
•
Check the bus configuration
A08526
No cyclic connection
•
Activate the controller with cyclic operation.
•
Check the parameters "Name of Station" and "IP of Station" (r61000,
r61001).
A08565
Consistency error affecting adjust-
able parameters
Check the following:
•
IP address, subnet mask or default gateway is not correct.
•
IP address or station name used twice in the network.
•
Station name contains invalid characters.
