Remove the external causes for this fault.
F07900 Motor blocked
• Make sure that the motor can rotate freely.
• Check the torque limit: r1538 for a positive direction of rotation; r1539 for
a negative direction of rotation.
Activate precontrol of the speed limiting controller (p1401 bit 7 = 1).
F07902 Motor stalled Check whether the motor data has been parameterized correctly and per-
form motor 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.
A07910 Motor overtemperature Check the motor load.
Check the motor's ambient temperature.
Check the KTY84 or PT1000 sensor.
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.
A07922 Torque/speed out of tolerance
• Check the connection between the motor and the load.
• Adapt the parameterization corresponding to the load.
F07924 Torque/speed too high
Rotary measurement activated
A07981 No enabling for rotary measure-
ment
Acknowledge pending faults.
Establish missing enables (see r00002, r0046).
A07991 Motor data identification activat-
Switch on the motor and identify the motor data.
F08501 Setpoint timeout
• Check the PROFINET connection.
• Set the controller to RUN mode.
• If the error occurs repeatedly, check the monitoring time set (p2044).
F08502 Monitoring time, sign-of-life ex-
• Check the PROFINET connection.
Send configuration data not valid
• Check the PROFINET configuration
A08511 Receive configuration data not
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 ad-
justable 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.
