S2: Slip Compensation For Elevators - YASKAWA L1000A Technical Manual

5.11 S: Elevator Parameters
■
S1-05: DC Injection / Position Lock Time at Stop
Determines how long the drive should perform DC Injection at stop. In CLV and CLV/PM, S1-05 determines how long
Position Lock should be performed. A setting of 0.00 disables S1-05.
No.
S1-05
■
S1-06: Brake Release Delay Time
Determines the time that must pass after an Up/Down command is entered before the output terminal set for "Brake
control" (H2- = 50) is triggered.
Adjusting this delay time can help when there is not enough time to develop the appropriate amount of motor flux. Be
sure to also increase the time S1-04 when setting S1-06 to relatively long delay time.
No.
S1-06
■
S1-07: Brake Apply Delay Time
Determines the time that must pass after zero speed is reached before the output terminal set for "Brake control"
(H2- = 50) is released.
No.
S1-07
■
S1-10: Run Command Delay Time
Sets the time the drive waits after receiving an Up/Down command before starting operation. The time set should give the
motor contactor enough time to close.
No.
S1-10
■
S1-11: Output Contactor Open Delay Time
Determines the time that must pass for an output terminal set for "Output contactor control" (H2-
after the drive has stopped and drive output has been shut off.
No.
S1-11

◆ S2: Slip Compensation for Elevators

The slip compensation function automatically adjusts the speed reference for leveling operation depending on the load
measured at constant speed. S2 parameters tune the slip compensation function to improve the landing accuracy. Slip
Compensation requires that the drive be set for V/f Control or Open Loop Vector Control.
■
S2-01: Motor Rated Speed
Sets the rated speed of the motor.
No.
