Remedy
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).
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
Carry out pole position identification.
Check the following:
Motor connection
•
Motor data
•
Not required
Acknowledge pending faults.
Establish missing enables (see r00002, r0046).
Switch on the motor and identify the motor data.
An error has occurred during the pole position identification.
Check the following:
Motor connection
•
Motor data
•
Check the PROFINET connection.
•
Set the control 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 control 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.
•
The PROFIenergy energy-saving mode is active.
The alarm automatically disappears when the energy-saving mode is
exited.
