Inverter with CU230P-2 Control Units
370 Operating Instructions, 11/2013, FW V4.6.6, A5E02430659B AG
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).
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
measurement
Acknowledge pending faults.
Establish missing enables (see r00002, r0046).
Motor identification activated
Switch on the motor and identify the motor data.
F08501 Setpoint timeout
• Check the PROFINET 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 PROFINET connection.
Send configuration data not valid
• Check the PROFINET configuration
A08511 Receive configuration data not
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
adjustable 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
