Remedy
Activate precontrol of the speed limiting controller (p1401 bit 7 = 1).
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.
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.
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 to RUN mode.
•
If the error 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.
