F06.09=6: the larger of AI1 and AI2
The formula for torque upper limit calculation is the same as described above, except that
the percentage of AI is the larger of AI1 and AI2.
F06.09=7: the smaller of AI1 and AI2
The formula for torque upper limit calculation is the same as described above, except that
the percentage of AI is the smaller of AI1 and AI2.
1. This code parameter represents the ratio of the output torque in the torque
limit action to the rated output torque of the inverter.
2. The user can set the upper torque limit according to the actual needs, to
protect the motor or meet the working conditions.
3. The electric mode and braking mode are set separately.

The parameters of the current loop PID regulator directly affect the performance and
stability of the system. The user does not need to change the default settings under normal
circumstances.

In the case of SVC control (e.g. F00.01=1) and zero-frequency operation, the inverter will
work according to the F06.17 setting.
F06.17=0
: braking by the set current of F06.18 for zero servo operation;
F06.17=1
: no processing;
F06.17=2
: the inverter freely stop running with its output blocked.
