12.4 C: Tuning
Do not enable this parameter in these conditions:
• Operating a motor in the middle speed range or low speed range
• Power supply voltage is a minimum of 10% more than the motor rated voltage
When you enable this parameter, if the power supply voltage is much less than the motor rated voltage, torque
control will not be accurate.

C3-21 Motor 2 Slip Compensation
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 OLV OLV/PM OLV/PM AOLV/PM EZOLV
Sets the modulation factor that starts the output voltage limit operation when C3-05 = 1 [Output
Voltage Limit Selection = Enabled].
V/f OLV OLV/PM OLV/PM AOLV/PM EZOLV
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 OLV OLV/PM OLV/PM AOLV/PM EZOLV
Sets the maximum drop width of the voltage reference when C3-05 = 1 [Output Voltage Limit
Selection = Enabled].
V/f OLV OLV/PM AOLV/PM EZOLV OLV/PM
Sets the gain for the motor 2 slip compensation function. Usually it is not necessary to change this
setting.
V/f OLV OLV/PM AOLV/PM EZOLV OLV/PM
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.
