Remedy
Check whether the motor data has been set correctly and perform a mo-
tor 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.
The inverter has activated the "Internal voltage protection" function"
(p1231 = 3). Deactivation of the internal voltage protection (p1231 ≠ 3)
only becomes active after POWER ON.
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.
Check the bus connection.
•
Set the controller into the RUN mode.
•
If the fault occurs repeatedly, check the monitoring time set p2044.
•
Check the bus connection.
Check the bus 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.
