F07862
External fault 1 … 3 Remove the external causes for these faults.
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 precontrol of the speed limiting controller (p1401 bit 7 = 1).
Increase hysteresis for overspeed signal p2162.
F07902 Motor stalled Check whether the motor data has been parameterized correctly and
perform 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 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
A07975 Traverse to the zero mark - set-
point input expected
The alarm disappears when the zero mark is detected.
A07980 Rotary measurement activated Not required
A07981 No enabling for rotary measure-
ment
Acknowledge pending faults.
Establish missing enables (see r00002, r0046).
A07991
Motor data 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 error 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 controller with cyclic operation.
• Check the parameters "Name of Station" and "IP of Station" (r61000,
r61001).
