Remedy
Check the motor cables.
Increase the ramp-up or ramp-down time (p1120).
Check the power cable connections.
•
Check the motor.
•
Check the current transformer.
•
Check the cables and contacts of the brake connection (a wire might
•
be broken).
Check the line voltage at the input terminals.
Check the line voltage setting (p0210).
Adapt the duty cycle.
•
Check whether the fan is running.
•
Check whether the ambient temperature is in the permissible range.
•
Check the motor load.
•
Reduce the pulse frequency.
•
Reduce the current of the DC current braking.
•
Check whether the fan is running.
•
Check the fan filter elements.
•
Check whether the ambient temperature is in the permissible range.
•
See F30035 and, in addition:
Check the motor load.
•
Check the line phases
•
Check the internal fan and if required replace.
Check the internal fan and if required replace.
Check the unit supply voltage (p0210).
•
Check the dimensioning of the line reactor.
•
Check that the sensor is connected correctly.
A PROFINET control is attempting to establish a connection with an in-
correct configuration telegram. Check to see whether "Shared Device" is
activated (p8929 = 2).
Correct name of station (p8920) and activate (p8925 = 2).
"Shared Device" is activated (p8929 = 2). However, only the connection
to a PROFINET control is available.
