Limit the max. inertia compensation torque to
prevent the inertia compensation torque from being
too large.

High-frequency ACR
proportional
coefficient
In the closed-loop vector control mode (P00.00=3),
when the running frequency is lower than the ACR
high frequency switching point (P08.21), the ACR PI
parameters are P03.09 and P03.10; and when the
running frequency is higher than the ACR high
frequency switching point, the ACR PI parameters
are P08.19 and P08.20.
Setting range of P08.19: 0–20000
Setting range of P08.20: 0–20000

Inertia identification
torque
Because of the friction, it is necessary to set
identification torque for normal inertia identification.
