Number Cause Remedy
F07896 Load monitoring, pump leakage
● Rectify the leakage in the pump circuit.
● For a false tripping, reduce the torque thresholds of the leakage
characteristic (p2186, p2188, p2190).
F07900 Motor blocked Check that the motor can run freely.
Check the torque limits (r1538 and r1539).
Check the parameters of the "Motor blocked" message (p2175, p2177).
F07901 Motor overspeed Activate the precontrol for the speed limiting controller (p1401 bit 7 = 1).
Increase the hysteresis for overspeed signal p2162.
F07902 Motor stalled Check whether the motor data has been set correctly and perform a 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.
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 measurement 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 controller to 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 adjusta‐
ble 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.
