C4: Torque Compensation - Omron V1000 User Manual

5.3 C: Tuning
No.
C3-02
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.
n C3-03: Slip Compensation Limit
Sets the upper limit for the slip compensation function as a percentage of the motor rated slip (E2-02).
No.
C3-03
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).
n C3-04: Slip Compensation Selection during Regeneration
When the slip compensation during regeneration function has been activated and regenerative load is applied, it might be
necessary to use a braking option (braking resistor, braking resistor unit, or braking unit).
Even if enabled, this function does not operate when the output frequency is too low.
No.
C3-04 Slip Compensation Selection during Regeneration
Setting 0: Disabled
Slip compensation is not provided. Depending on the load and operation mode (motoring or regenerative) the actual motor
speed will be lower or higher than the frequency reference.
Setting 1: Enabled
Slip compensation is enabled during regenerative operation. It will not be active at output frequencies below 6 Hz.
n C3-05: Output Voltage Limit Operation Selection
Determines if the motor flux reference is automatically reduced when output voltage reaches the saturation range.
No.
C3-05
Setting 0: Disabled
Setting 1: Enabled

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 parameters make sure the motor parameters and V/f pattern are set properly or perform
Auto-Tuning.
n C4-01: Torque Compensation Gain
Sets the gain for the torque compensation function.
