Remedy
Increase p2163 and/or p2166.
Increase the torque, current and power limits.
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.
•
Check the connection between the motor and the load.
•
Adapt the parameterization corresponding to the load.
•
Not required
Not required
Acknowledge pending faults.
Establish missing enables (see r00002, r0046).
Switch on the motor and identify the motor data.
Check the PROFINET connection.
•
Set the controller into the RUN mode.
•
If the fault occurs repeatedly, check the monitoring time set p2044.
•
Check the PROFINET connection.
Check the PROFINET configuration
•
Activate the controller with cyclic operation.
•
Check the parameters "Name of Station" and "IP of Station" (r61000,
•
r61001).
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.
•
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!
