Parameters 11-53
176 Autotune Errors
Autotune Errors shows the results of the auto-tune tests. The test
results are divided into four categories: slip calculations, leakage
inductance tests, resistance tests, and flux current tests. If a fault
occurred during the auto-tune tests, the appropriate bit is set in
Autotune Errors. If no bits are set, the drive passed all of the
auto-tune tests.
The bits are defined as follows:
Parameter number 176

Bit Description Bit Description Bit Description
0
Slip <= 0 Resistance Tests Flux Current Tests
Slip is 0 or negative. 6 Res- > 0 Spd 11 Flx-Atune Lo
Inductance Tests Not at zero speed. Auto-tune setpoint is too low.
1 Ind- > 0 Spd 7 Res-Sign Err 12 Flx-Flux < 0
Not at zero speed. Sign error. Flux less than zero.
2 Ind-Sign Err 8 Res- 0 Cur 13 Flx-Cur>MCur
Sign error or negative Lsigma. Zero current. Flux current > rated motor current.
3 Ind- 0 Cur 9 Res-SW Err 14 Flx-En Drop
Zero current. Software error. Enable dropout.
4 Ind-A/D Ovfl 10 Res-En Drop 15 Flx-Hi Load
A/D overflow at minimum gain. Enable dropout. The load is too high.
5 Ind-En Drop
Enable dropout.
