V/f CL-V/f OLV CLV AOLV
Sets the slip compensation during regenerative operation function for motor 2.
0 : Disabled
1 : Enabled Above 6Hz
2 : Enabled Above C3-15
V/f CL-V/f OLV CLV AOLV
Sets the slip compensation function mode.
0 : Normal
1 : Advanced
V/f CL-V/f OLV CLV AOLV
Sets the gain for the torque compensation function. Use this parameter value for motor 1 when
operating multiple motors.
Note:
If A1-02 = 8 [Control Method Selection = EZOLV], you cannot change the setting while the
drive is running.
V/f CL-V/f OLV CLV AOLV
Sets the torque compensation delay time. Usually it is not necessary to change this setting.
Note:
• When A1-02 = 5 [Control Method Selection = OLV/PM], you cannot change the setting while
the drive is running.
• When A1-02 = 8 [EZOLV], you cannot change the setting while the drive is running.
V/f CL-V/f OLV CLV AOLV
Set the amount of torque reference for forward start as a percentage of the motor rated torque.
V/f CL-V/f OLV CLV AOLV
Sets the amount of torque reference for reverse start as a percentage of the motor rated torque.
V/f CL-V/f OLV CLV AOLV
Sets the starting torque constant to use with C4-03 and C4-04 [Torque Compensation @ FWD/REV
Start].
V/f CL-V/f OLV CLV AOLV
Sets the value if ov [Overvoltage] occurs with sudden changes in the load, at the end of acceleration,
or at the start of deceleration.
V/f CL-V/f OLV CLV AOLV
Sets the gain for motor 2 torque compensation function when using the Motor Switch function.
V/f CL-V/f OLV CLV AOLV
If there is slow oscillation at low speeds, adjust this setting. Usually it is not necessary to change this
setting.
Increase this parameter in 1.0 Hz increments when current ripples and torque ripples occur during
low-speed operation. Set this parameter to 0.0 to disable the function if increasing the value does not
fix the problem.
Note:
Set C4-20 [Voltage Compensation Adjust 1] ≠ 0 to enable this parameter.
V/f CL-V/f OLV CLV AOLV
Sets voltage precision compensation. Usually it is not necessary to change this setting.
V/f CL-V/f OLV CLV AOLV
Sets voltage precision compensation. Usually it is not necessary to change this setting.
V/f CL-V/f OLV CLV AOLV
Sets the Current control gain. Usually it is not necessary to change this parameter.
