After completion of the parameter identification, warning messages may be dis-
played.
Depending on the warning message code, the following instructions should be fol-
lowed and the measures indicated should be taken.
Warning Messages
Code Measures / Remedy
SA011 Current Controller non typical value; refer to 16.5.1.
SA012 Current Controller non typical value with 2 kHz; refer to chapter 16.5.1.
SA014 Current Controller non typical value with 4 kHz; refer to chapter 16.5.1.
SA018 Current Controller non typical value with 8 kHz; refer to chapter 16.5.1.
SA021 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).
SA022 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).
SA031 Shorten Motor Line using Switchfrequ. 16 kHz.
SA032 Shorten Motor Line using Switchfrequ. 12 kHz and higher.
SA033 Shorten Motor Line using Switchfrequ. 8 kHz and higher.
SA041 The slip speed was not determined correctly. Check the values entered for
parameters
Rated speed
372 and
Rated frequency
375.
SA042 The slip speed was not determined correctly. Check the values entered for
parameters
Rated speed
372 and
Rated frequency
375.
SA051 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.
SA052 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.
SA053 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.
