P11.12
Tracking voltage Kd
0.0~100.0
0.0
Kd during tracking process. If the value is too small, the suppression of overshoot current will be not
obvious in the tracking process; if it is too large, an overcurrent will be observed during the tracking.

Tracking exit delay (ms)
1000~65000
100
Ensure a smooth exit from the tracking process. Increase of this value will be conducive to a smooth
exit.

Maximum current during
tracking (%)
0.0~200.0
100.0
The percentage of the rated current of motor. Ensure that the maximum current during tracking is
lower than the rated current of the frequency inverter when a small inverter is used for a larger motor.
If an overcurrent is observed during the tracking, this value should be reduced.

If an overvoltage is observed or the P60.09 is greater than 600V during the tracking, the value
should be reduced.

Tracking initial frequency (Hz)
0.00~360.00
50.00
It is usually set to the maximum running frequency before tracking. If the inertial stopping velocity
of the system decreases fast, the value can be reduced appropriately.

P11.19
Reverse breaking current (%)
0.0~100.0
20.0
Motor breaking control in the lifting industry is adopted. The breaking condition can only be met
when the reverse starting current of the motor is greater than the current of P 11.19.

Stopping mode option
0~4
0
Different stopping modes can be used for different applications.
0: The inverter blocks the output and the motor stops freely;
1: The inverter decelerates and stop running according to the set deceleration time;
2: The inverter decelerates and stops according to the set DC braking. When the frequency is lower
than the DC braking starting frequency P12.03, the DC braking current P12.04 will be injected, and
