Gain
(033E)
RUN
Note:
Correctly set these parameters before changing the slip compensation gain:
• E4-01 [Motor 2 Rated Current]
• E4-02 [Motor 2 Rated Slip]
• E4-03 [Motor 2 Rated No-Load Current]
Use these settings to adjust this parameter as necessary:
• If the motor speed is slower than the frequency reference, increase C3-01 in 0.1 unit increments.
• If the motor speed is higher than the frequency reference, decrease the setting of this parameter in 0.1-unit
increments.

Use these settings to adjust this parameter as necessary:
• When the speed is not stable, increase the setting.
• When the slip compensation response is too slow, decrease the setting.

V/f CL-V/f OLV CLV AOLV
Sets the modulation factor that starts the output voltage limit operation when C3-05 = 1 [Output
Voltage Limit Selection = Enabled].
V/f CL-V/f OLV CLV AOLV
Sets the modulation factor used with C3-18 [Output Voltage Limit Level] for the output voltage limit
operation when C3-05 = 1 [Output Voltage Limit Selection = Enabled].
V/f CL-V/f OLV CLV AOLV
Sets the maximum drop width of the voltage reference when C3-05 = 1 [Output Voltage Limit
Selection = Enabled].
V/f CL-V/f OLV CLV AOLV
Sets the gain for the motor 2 slip compensation function. Usually it is not necessary to change this
setting.
V/f CL-V/f OLV CLV AOLV
Sets the slip compensation delay time for motor 2 when speed is unstable or when the slip
compensation response is too slow. Usually it is not necessary to change this setting.
V/f CL-V/f OLV CLV AOLV
Sets the upper limit for the slip compensation function as a percentage of the motor 2 rated slip.
