8.6.4 Motor temperature monitoring
The motor temperature either is monitored via a PTC inside the motor or via a thermal
contact. The response of the motor temperature monitoring (Error, Warning, Off) can be
defined via C0120.

8.6.5 Output stage temperature monitoring
If the output stage temperature is > 100 °C for 3 seconds, an error message is output. You
can only acknowledge the message if the output stage temperature has been < 90 °C for
5 seconds. The current output stage temperature can be read in C0056.
8.6.6 Parameter error
After power−on, all parameter data are read out from the flash memory and/or from the
external data connector. Then a checksum verification is carried out. A parameter error is
triggered if the checksum saved does not correspond to the checksum calculated or if a
new software version with a changed parameter repository has been loaded.
How to eliminate a parameter error:
1. Set all parameters to the Lenze setting (C0002 = 1).
2. Transfer the valid parameter set for the respective application again.
3. Wait until the PAr display goes out.
4. Switch off the supply voltage and then switch it on again.
) Note!
During the download of the parameters via PC or PDA, never switch off the
supply voltage as long as PAr is displayed in the 7−segment display!
Otherwise the transfer of the parameters is incomplete.
8.6.7 External error
The tripping of an external error is parameterised via the assignment logic (C0410). In
order to generate the fault message, a digital signal is used, e. g. a digital input.
