C4-02: Torque Compensation Primary Delay Time
■
Sets the delay time used for applying torque compensation.
No.
C4-02 Torque Compensation Primary Delay Time
<1> For details on the default settings, refer to
Adjustment
Although C4-02 rarely needs to be changed, adjustments may help in the following situations:
• If the motor vibrates, increase C4-02.
• If the motor responds too slowly to changes in the load, decrease C4-02.
C4-03: Torque Compensation at Forward Start (OLV)
■
Sets the amount of torque at start in the forward direction in order to improve motor performance during start with a
heavy load. Compensation is applied using the time constant set in parameter C4-05. Enable this function when the load
pulls the motor in reverse when starting with a Forward run command. Setting of 0.0% disables this feature.
No.
C4-03 Torque Compensation at Forward Start
■ C4-04: Torque Compensation at Reverse Start (OLV)
Sets the amount of torque reference at start in the reverse direction in order to improve motor performance during start
with heavy load. Compensation is applied using the Torque Compensation Time set in parameter C4-05. Enable this
function if the load pulls the motor in the forward direction when starting with a Reverse run command. Setting 0.0%
disables this feature.
No.
C4-04 Torque Compensation at Reverse Start
C4-05: Torque Compensation Time Constant (OLV)
■
This parameter is the time constant for applying the torque compensation at start that is set in C4-03 and C4-04.
No.
C4-05 Torque Compensation Time Constant
C4-06: Torque Compensation Primary Delay Time 2 (OLV)
■
This time constant is used during Speed Search or during regenerative operation. Increase the value if an overvoltage
fault occurs with sudden changes in the load or at the end of acceleration with high inertia load.
No.
C4-06 Torque Compensation Primary Delay Time 2
Note: If C4-06 is set to a relatively large value, be sure to also increase the setting in n2-03 (AFR Time Constant 2) proportionally.
C4-07: Motor 2 Torque Compensation Gain
■
Functions for motor 2 in the same way that C4-01 functions for motor 1.
Sets the gain for the torque compensation function of the motor 2.
No.
C4-07 Motor 2 Torque Compensation Gain
