Description
In the closed-loop vector control mode
(P00.00=3), when the frequency is lower
than the current-loop
switching threshold
current-loop PI parameters are P03.09 and
P03.10; and when the frequency is higher
than the current-loop
switching threshold
current-loop PI parameters are P03.37 and
P03.38.
Setting range of P03.37: 0–20000
Setting range of P03.38: 0–20000
Setting range of P03.39: 0.0–100.0% (of the
maximum frequency)
0: Disable
1: Enable
The max. inertia compensation torque is
limited to prevent inertia compensation
torque from being too large.
Setting range: 0.0–150.0% (of the motor
rated torque)

Setting range: 0–10
Due to friction force, it is required to set
certain identification torque for the inertia
identification to be performed properly.
Setting range: 0.0–100.0% (of the motor
rated torque)
0: No operation
