C3: Slip Compensation; C4: Torque Compensation - Omron J1000 User Manual

5.3 C: Tuning
n C2-01 to C2-04: S-Curve Characteristics
C2-01 through C2-04 set separate S-curves for each section of the acceleration or deceleration.
No.

C2-02
C2-03
C2-04
Figure 5.6 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

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.
n C3-01: Slip Compensation Gain
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
n 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.
No.

C4: Torque Compensation

The torque compensation function compensates for insufficient torque production at start-up or when a load is applied.
Note: Before making changes to the torque compensation gain make sure the motor parameters and V/f pattern are set properly.
n C4-01: Torque Compensation Gain
Sets the gain for the torque compensation function.
No.
