123.8 Result current controller Kp
This parameter shows the calculated current controller Kp value at a PWM frequency of
4 kHz.
123.9 Result current controller Tn
This parameter shows the identified reset time for the current controller.
123.10 Parameters takeover
The identified parameters are used internally for the motor control, if bit 3 is active.
The following parameters are written to:
1 Z47.7– P-gain Iq = Z47.9– P-gain Id
The P-gains entered always refer to 4 kHz PWM. The adjustment of the PWM fre-
quency to other frequencies takes place internally, automatically.
2 Z47.8– Reset time Iq = Z47.10– Reset time Id
3 Motor parameters that are relevant to decoupling feedforward, IxR feedforward and
current prediction in the current controller:
– Synchronous motor
Z107.29– Stator resistance
Z107.34– Inductance Lq
Z107.35– Inductance Ld (with Parameter 107.35 = Parameter 107.34)
– Asynchronous motor
Z107.29– Stator resistance
Z107.30– Stator leakage inductance

NOTE!
There is no way to prove, if autotuning was successful.
