After the machine data (and the speed sensor data, if applicable) have been entered,
the calculation or examination of the parameters is started automatically. The display
changes
over to "CALC" for a short time. If the verification of the machine data is
successful, the guided commissioning procedure continues with the identification of
the parameters.
Verification of the machine data should only be skipped by experienced users. The
configurations contain complex control processes which depend to a large degree on
the correctness of the machine parameters entered.
The warning and error messages displayed during the verification process have to
be observed. If a critical condition is detected during the guided commissioning, it is
displayed by the control unit. Depending on the deviation from the expected parame-
ter value, either a warning or an error message is displayed.
To ignore the warning or error messages, press the ENT key. The guided com-
missioning is continued. However, it is recommended that the data be checked
and corrected if necessary.
To correct the entered parameter values after the warning or error message,
press the ESC key. Use the arrow keys to switch to the parameter value which is
to be corrected.

Measures / Remedy
SA000
No warning message present. This message can be read out via an op-
tional communication board.
SA001
The value of the parameter
Rated voltage
370
is out of the rated voltage
range of the frequency inverter. The maximum reference voltage is indi-
cated on the nameplate of the frequency inverter.
SA002
For a three-phase motor, the calculated efficiency is in the limit range.

SA003
The value entered for parameter
Rated cos phi
374
is outside of the nor-
mal range (0.6 to 0.95). Check the value.
SA004
For three-phase motor, the calculated slip is in the limit range.
