After completion or during the parameter identification, error messages may be
displayed. Depending on the error code, the following instructions should be followed
and the measures indicated should be taken.

Code
SA0021 The stator resistance is very high. The following causes are possible:
− The motor cable cross-section is not sufficient.
The motor cable is too long.
−
The motor cable is not connected correctly.
−
The contacts are not in a proper condition (corrosion).
−
SA0022 The rotor resistance is very high. The following causes are possible:
The motor cable cross-section is not sufficient.
−
The motor cable is too long.
−
The motor cable is not connected correctly.
−
The contacts are not in a proper condition (corrosion).
−
SA0041 The slip speed was not determined correctly. Check the values entered for
Rated Speed
parameters
SA0042 The slip speed was not determined correctly. Check the values entered for
Rated Speed
parameters
SA0051 The machine data for star connection were entered, the motor, however, is
connected in delta. For star operation, change the motor cable connection.
For delta operation, check the entered rated motor values.
Repeat the parameter identification
SA0052 The machine data for delta connection were entered, the motor, however,
is connected in star. For delta operation, change the motor cable
connection. For star operation, check the entered rated motor values.
Repeat the parameter identification
SA0053 A phase asymmetry was measured. Check the cables at the terminals of
the motor and the frequency inverter for proper connection and check the
contacts for corrosion.
Code
SF0011 The main inductance measurement has failed because the motor has a
high slip. Correct the rated motor values in parameters 370, 371, 372,
374, 375 and 376. Carry out the guided commissioning once again. In
case an error message is displayed again, enter the value 110 for
Configuration
parameter
characteristic) if value 410 was set so far. Carry out the guided
commissioning once again.
SF0012 The leakage inductance measurement has failed because the motor has a
high slip. Correct the rated motor values in parameters 370, 371, 372,
374, 375 and 376. Carry out the guided commissioning once again. In
case an error message is displayed again, enter the value 110 for
Configuration
parameter
characteristic) if value 410 was set so far. Carry out the guided
commissioning once again.
SF0021 The measurement of the stator resistance did not deliver a plausible value.
Check the cables at the terminals of the motor and the frequency inverter
for proper connection and check the contacts for corrosion and safe
contact. Repeat the parameter identification
SF0022 The measurement of the rotor resistance did not deliver a plausible value.
Check the cables at the terminals of the motor and the frequency inverter
for proper connection and check the contacts for corrosion and safe
contact. Repeat the parameter identification
