Alarms and faults
This is only an extract. The complete list of alarms and faults can be found in List
Manual CU230P (A5E02297932A AE).
Alarms
Solution
Parameterization on the memory card has been created with a different type of
module (order number, MLFB).
Check the module parameters and recommission if necessary.
Set the date and time of day of the real-time clock: p8400 (RTC time), p8401
(RTC date)
Deactivate the alarm: p8405 = 0.
Carry out maintenance and reset the maintenance interval (p0651).
A PROFIBUS master is attempting to establish a connection with a faulty
configuration telegram.
Check the bus configuration on the master and slave side.
Establish the bus connection and switch on the communication partners.
Possibly adapt p2040.
Set the PROFIBUS master to RUN.
The cyclic connection to the PROFIBUS master is interrupted.
Establish the PROFIBUS connection and activate the PROFIBUS master with
cyclic operation.
Check that the sensor is correctly connected.
Check that the ambient temperature is within the defined limit values.
Check that the load conditions and duty cycle are appropriately dimensioned.
Check whether there has been a cooling system failure.
Reduce the motor load.
Check the ambient temperature and the motor ventilation.
Check the thermal time constant p0611.
Check overtemperature fault threshold p0605.
Check that the sensor is correctly connected.
Check the parameter assignment (p0601).
Automatic restart is active. During voltage recovery or when remedying the causes
of pending faults, the drive is automatically switched back on.
Block the automatic restart (p1210 = 0).
Abort the restart process by removing the switch-on command (p8040).
