■ S1-26: Emergency Stop Start Level
Sets the Emergency Stop Start Level as a percentage of the Maximum Output Frequency. This setting is available when
the control mode is set to Closed Loop Vector Control (A1-02 = 3) or Closed Loop Vector Control for PM Motors
(A1-02 = 7) and the stopping method is set to Elevator Emergency Stop (b1-03 = 4).
The drive coasts to a stop after the Up/Down command is cleared and when the value of U1-05 (Speed Feedback) is equal
to or greater than the value of S1-26 (Emergency Stop Start Level).
The drive ramps to a stop after the Up/Down command is cleared and when the value of U1-05 (Speed Feedback) is lower
than the value of S1-26 (Emergency Stop Start Level).
◆ 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.
■ 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.
■ S2-05: Slip Compensation Torque Detection Delay Time
Sets a delay time before detecting torque for slip compensation.
■ S2-06: Slip Compensation Torque Detection Filter Time Constant
Sets the filter time constant applied to the torque signal used for the slip compensation value calculation.
