■ S3-25: DC Injection Gain in Regenerative Operation
In OLV Control, S3-25 sets a gain level for DC Injection at stop (S1-03) for when the regenerative load reaches 100%. At
that time, the current applied during DC Injection at stop is determined as S1-03
× S3-25.
■ S3-26: DC Injection Gain in Motoring Operation
In OLV Control, S3-26 sets a gain level for DC Injection at stop (S1-03) when the motoring load reaches 100%. At that
time, the current applied during DC Injection at stop is determined as S1-03
× S3-26.
■ S3-27: Torque Compensation Value with Load Condition 1
Adjusts the analog signal from a load sensor for torque compensation. Refer to Adjusting the Torque Compensation at
Start on page 88 for details.
■ S3-28: Torque Compensation Value with Load Condition 2
Adjusts the analog signal from a load sensor for torque compensation. Refer to Adjusting the Torque Compensation at
Start on page 88 for details.
■ S3-29: Analog Input from Load Sensor with Load Condition 1
Adjusts the analog signal from a load sensor for torque compensation. Refer to Adjusting the Torque Compensation at
Start on page 88 for details.
■ S3-30: Analog Input from Load Sensor with Load Condition 2
Adjusts the analog signal from a load sensor for torque compensation. Refer to Adjusting the Torque Compensation at
Start on page 88 for details.
■ S3-34: Anti-Rollback Torque Bias 1
Sets an intermediary value for the torque bias used for Anti-Rollback when Position Lock at start is performed. This
setting rarely needs to be changed.
