1.3 C: Tuning
82 YASKAWA ELECTRIC SIEP C710606 10A YASKAWA AC Drive - V1000 PRELIM. Programming Manual
• 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.
Note: Default setting is 0.0 in V/f Control (A1-02 = 0). Default setting is 1.0 in Open Loop Vector
Control (A1-02 = 2).
This parameter is disabled when using V/f Control with Simple
PG Feedback (H6-01 = 3).
■
C3-02: Slip Compensation Primary Delay Time
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.
Note: When using V/f Control (A1-02 = 0), the default setting becomes 2000 ms. When using Open
Loop Vector Control (A1-02 = 2), the default setting becomes 200 ms. This function is not
available when using V/f Control with Simple PG Feedback.
■ C3-03: Slip Compensation Limit
Sets the upper limit for the slip compensation function as a percentage of the motor rated slip
(E2-02).
The slip compensation limit is constant throughout the constant torque range. In the constant
power range it is increased based on C3-03 and the output frequency as shown in the
following diagram.
Note: This parameter is disabled when using V/f Control with Simple PG Feedback
Control (H6-01 = 3).
