■ S2-02/S2-03: Slip Compensation Gain in Motoring Mode / Regenerative Mode
Slip compensation for leveling speed can be set separately for motoring and regenerative states to help improve the
accuracy of leveling.

♦ S3: Start/Stop Optimization
■ S3-01 / S3-02: Position Lock Gain at Start 1 / 2
Sets gain levels 1 and 2 for the Position Lock at start function. Position Lock at start adjusts the internal torque reference
value depending on the position deviation to hold the car in place when the brake is released. S3-01 sets the gain used to
adjust the speed reference During Position Lock. S3-02 sets gain to adjust the internal torque reference directly (Anti
Rollback function).
Increase S3-01 and S3-02 if there is a problem with rollback when the brake is released. Decrease S3-01 and S3-02 if
motor oscillation occurs during Position Lock.
No.

Note: 1. Check the C 5 -D D param eters to make sure the speed control loop settings are correct before making any adjustm ents to the Position
Lock gain.
2. Sometimes a fault may occur w ith detecting the direction o f m otor rotation (dv4) when using Closed Loop Vector for PM motors. To
correct this, either increase the settings o f S3-01 and S3-02, or increase the num ber o f pulses needed to trigger dv4 (F1-19).
■ S3-03: Position Lock Gain at Stop
Sets the gain used by the Position Lock control loop at stop to hold the car in place while the brake is applied.
Setting S3-03 to a high value will increase the ability of the drive to hold the car in place. Setting S3-03 too high can
cause motor oscillation and car vibration.

Note: 1. Check the С5-СЮ param eters to make sure the speed control loop settings are correct before making any adjustm ents to the Position
Lock gain.
2. Faults may occur when detecting the direction o f m otor rotation (dv4) when using CLV/PM. To correct this, either increase the
settings o f S3-01 and S3-02, or increase the num ber o f pulses required to trigger dv4 (F1-19).
