The drive uses the time constant set in
C4-05 [Trq Comp Time]
to do the torque compensation function.
This is available only when you start the motor with the reverse Run command.

M2 Trq Comp Delay Time
Sets the value if
ov [Overvoltage]
occurs with sudden changes in the load, at the end of
acceleration, or at the start of deceleration.
150 ms
(0 - 10000 ms)
Sets the time constant used during Speed Search or during regenerative operation when
ov
occurs.
Adjust this parameter in the following circumstances.
•
Gradually reduce the setting in 10 ms increments and check the performance to improve motor torque speed
response when
ov
occurs.
Note:
•
Ensure that
C4-06 ≥ C4-02 [Trq Comp Delay Time]
.
•
Increase the setting value of
n2-03 [AFR Time 2]
proportional to
C4-06
.

M2 Trq Comp Gain
Sets the gain for motor 2 torque compensation function when using the Motor Switch function.
1.00
(0.00 - 2.50)
In V/f Control, adjust the value in 0.05-unit increments for these conditions:
•
When torque is not sufficient during low-speed operation of 10 Hz or less, increase the setting value
•
When there is vibration in the motor or when the motor hunts when operating the drive with a light load,
decrease the setting value
•
When you use a long motor cable, increase the setting value.
Note:
•
Adjust
C4-07
to make sure that the output current is not more than the drive rated current during low-speed operation.
•
When
A1-02 = 2 [Control Method = OLVector]
, usually it is not necessary to change the setting. Torque accuracy will decrease.
