12.3 C: TUNING
496 SIEPCYEUOQ2V01A Q2V Technical Manual
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: M2 Slip Comp Gain
No.
(Hex.)
Name Description
Default
(Range)
C3-21
(033E)
RUN
M2 Slip Comp Gain
Sets the gain for the motor 2 slip compensation function. Usually it is not necessary to change this
setting.
Determined by E3-01
(0.0 - 2.5)
Note:
Correctly set these parameters before changing the slip compensation gain:
• E4-01 [M2 Rated Current (FLA)]
• E4-02 [M2 Rated Slip]
• E4-03 [M2 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.
■ C3-22: M2 Slip Comp DelayTime
No.
(Hex.)
Name Description
Default
(Range)
C3-22
(0241)
RUN
M2 Slip Comp DelayTime
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.
Determined by E3-01
(0 - 10000 ms)
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.
