5.11 S: Elevator Parameters
264 YASKAWA ELECTRIC SIEP C710616 38F YASKAWA AC Drive - L1000A Technical Manual
■ S3-37: Position Deviation Level to Apply Anti-Rollback Torque Bias 1
Sets the position deviation level to activate at Anti-Rollback Torque Bias 1 (S3-34). This setting rarely needs to be
changed.
■
S3-38: Position Deviation Level to Apply Anti-Rollback Torque Bias 2
Determines the position deviation level when the drive should switch from the Anti-Rollback torque bias set in S3-34 to
the torque bias set in S3-35. This setting rarely needs to be changed.
■
S3-39: Anti-Rollback Integral Gain
Determines the drive responsiveness for Anti-Rollback during Position Lock.
Increasing the value set to S3-39 may help if there is still too much deviation from the Position Lock start position after
Position Lock gain 1 and gain 2 have already been adjusted. Lower S3-39 if oscillation occurs. This parameter rarely
needs to be changed.
■
S3-40: Anti-Rollback Movement Detection
Sets the amount of speed feedback signal pulses to detect a movement of the rotor.
■
S3-41: Position Lock Gain at Start 2 Reduction
Sets a reduction factor for the Position Lock Gain at Start 2 (Anti Rollback Gain) set in parameter S3-02.
If the motor rotation (i.e., car movement) is below the movement detection level set to S3-40, the drive will reduce the
Anti-Rollback gain according to the gain reduction level set in S3-41.
◆ S4: Rescue Operation
Rescue Operation switches to a backup battery or some other UPS during a power outage. Refer to Rescue Operation on
page 134 for details.
■
S4-01: Light Load Direction Search Selection
Enables and disables the Light Load Direction Search.
Setting 0: Disabled
Setting 1: Enabled
Setting 2: Enabled for motor 1 only
