Remedy
Explanation: 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.
Carry out maintenance and reset the maintenance interval (p0651).
Explanation: A PROFIBUS master is attempting to establish a connection
with a faulty configuration telegram.
Check the bus configuration on the master and slave side.
Explanation: The cyclic connection to PROFIBUS master is interrupted.
Establish the PROFIBUS connection and activate the PROFIBUS master
with cyclic operation.
Check that the sensor is connected correctly.
- Is the ambient temperature within the defined limit values?
- Are the load conditions and duty cycle configured accordingly?
- Has the cooling failed?
Check and if necessary reduce the motor load.
Check the motor's ambient temperature.
Check thermal time constant p0611.
Check overtemperature fault threshold p0605.
Check that the sensor is connected correctly.
Check the parameter assignment (p0601).
Explanation: The automatic restart (AR) is active. During voltage recovery
and/or when remedying the causes of pending faults, the drive is
automatically switched back on.
The signal for "external alarm 1" has been triggered.
Parameters p2112, p2116 and p2117 determine the signal sources for the
external alarm 1... 3.
Remedy: Rectify the cause of this alarm.
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.
Check the overtemperatures of the thermal model (p0626 ... p0628).
Not required
Not required
Acknowledge pending faults.
Establish missing enables (see r00002, r0046).
