Warning!

•
Canceling the operation with the ESC key or withdrawing the release signal S1IND
results in an incomplete take-over of the values.
Note:
After completion of the parameter identification, warning messages may be displayed.
Depending on the warning message code, the following instructions should be fol-
lowed and the measures indicated should be taken.

Switch off power supply before connecting and disconnecting control
terminal S1IND.
When the frequency inverter is disconnected from power supply, the
mains, DC-link voltage and motor terminals may still be live for some
time. Wait for some minutes until the DC link capacitors have discharged
before starting to work at the unit.
The unit may only be connected with the power supply switched off.
Make sure that the frequency inverter is discharged.
Confirm the final "rEAdY" message by pressing the ENT key.
In the case of higher requirements as regards the accuracy of the
speed/torque control, you should carry out the guided commissioning
procedure once again under operating conditions because part of the
machine data depends on the operating temperature.
During this procedure, confirm the machine data already entered.
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

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 connec-
tion. 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.
