Number
Cause
Remedy
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
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 PROFINET connection.
• Set the control into the RUN mode.
• If the fault occurs repeatedly, check the monitoring time set p2044.
F08502 Monitoring time, sign-of-life expired
• Check the PROFINET connection.
F08510
Send configuration data not valid
• Check the PROFINET configuration
A08511 Receive configuration data not
valid
A08526 No cyclic connection
• Activate the control 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.
F08700 Communications error A CAN communications error has occurred. Check the following:
• Bus cable
• Baud rate (p8622)
• Bit timing (p8623)
• Master
Start the CAN controller manually with p8608 = 1 after the cause of the
fault has been resolved!
F13100 Know-how protection: Copy protec-
tion error
The know-how protection and the copy protection for the memory card
are active. An error occurred when checking the memory card.
• Insert a suitable memory card and switch the inverter power supply
temporarily off and then on again (POWER ON).
• Deactivate the copy protection (p7765).
