C2-01 to C2-04: S-Curve Characteristics
n
C2-01 through C2-04 set separate S-curves for each section of the acceleration or deceleration.
No.
C2-01
C2-02
C2-03
C2-04
Figure 5.27
explains how S-curves are applied.
Setting the S-curve will increase the acceleration and deceleration times.
Actual accel time = accel time setting + (C2-01 + C2-02)/2
Actual decel time = decel time setting + (C2-03 + C2-04)/2
C3: Slip Compensation
u
The Slip Compensation function prevents motor speed loss due to an increase in load.
Note:
Before making changes to the Slip Compensation parameters, make sure the motor parameters and V/f pattern are set properly or perform
Auto-Tuning.
C3-01: Slip Compensation Gain
n
This parameter sets the gain for the motor slip compensation function. Although this parameter rarely needs to be changed,
adjustments might be needed under the following situations:
• If the speed at constant frequency reference is lower than the frequency reference, increase C3-01.
• If the speed at constant frequency reference is higher than the frequency reference, decrease C3-01.
No.
C3-01
C3-02: Slip Compensation Primary Delay Time
n
Adjusts the filter on the output of the slip compensation function. Although this parameter rarely needs to be changed,
adjustments might be needed under the following situations:
• Decrease the setting when the slip compensation response is too slow.
• Increase this setting when the speed is not stable.
No.
C3-02
C3-03: Slip Compensation Limit
n
Sets the upper limit for the slip compensation function as a percentage of the motor rated slip (E2-02).
