■ S2: Slip Compensation for Elevators
■ S3: Start/Stop Optimization
No. Name Description Setting
S2-01 Motor Rated Speed Sets the motor rated speed.
Default: 1380 rpm
Min: 300 rpm
Max: 1800 rpm
S2-02
Slip Compensation Gain in
Motoring Mode
Slip compensation for leveling speed can be set separately for motoring and
regenerative states. This can help improve the accuracy of leveling.
Default: 0.7
Min: 0.0
Max: 5.0
S2-03
Slip Compensation Gain in
Regenerative Mode
Default: 1.0
Min: 0.0
Max: 5.0
S2-05
Slip Compensation Torque
Detection Delay Time
Sets a delay time before detecting torque for slip compensation.
Default: 1000 ms
Min: 0 ms
Max: 10000 ms
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.
Default: 500 ms
Min: 0 ms
Max: 2000 ms
No. Name Description Setting
S3-01
Position Lock Gain at Start
1
Sets gain levels 1 and 2 for the Position Lock function. Position Lock at start attempts
to keep the car position when opening the brake in order to avoid roll back.
Default: 5
Min: 0
Max: 100
S3-02
Position Lock Gain at Start
2
(Anti Rollback Gain)
Default: 0.00
Min: 0.00
Max: 100.00
S3-03
Position Lock Gain at Stop
Sets the Position Lock gain at stop. Position Lock at stop keeps the car in position
until the brake has been applied entirely.
Default: 5
Min: 0
Max: 100
S3-04 Position Lock Bandwidth
Determines the bandwidth around the stop position in which a digital output
programmed for “Within Position Lock Bandwidth” (H2- = 33) is closed.
Default: 10
Min: 0
Max: 16383
S3-10
Starting Torque
Compensation Increase
Time
Sets a time constant for the torque reference to reach 300%. Enabled by setting an
analog input terminal for torque compensation (H3- = 14).
Default: 500 ms
Min: 0 ms
Max: 5000 ms
S3-12
Starting Torque
Compensation Bias in
Down Direction
Adds a bias to torque compensation value from the load cell when moving in the
down direction.
Default: 0
Min: -40.0%
Max: 40.0%
S3-14
Torque Compensation
Diminish Speed
Sets the speed level for torque compensation to diminish during the time determined
by S3-15. Sets as a percentage of the maximum output frequency (E1-04). A setting
of 0.0% disables this function.
Default: 0.0%
Min: 0.0%
Max: 200.0%
S3-15
Torque Compensation
Diminish Time
Sets the time for torque compensation to diminish once motor speed reaches the level
set in S3-14.
Default: 1000 ms
Min: 0 ms
Max: 5000 ms
S3-16
Torque Limit Reduction
Time
Determines the reduction rate used bring the internal torque reference value down to
zero after Position Lock at Stop has finished.
Rate =
Default: 100 ms
Min: 0 ms
Max: 10000 ms
S3-20 Dwell 2 Speed Reference
Sets the speed reference for the Dwell 2 function.
Note: A setting of 0.00 essentially disables the Dwell 2 function.
Default: 0.00%
Min: 0.00%
Max: 100.00%
S3-21 Dwell 2 End Speed
The Dwell 2 function will end when the drive reaches this speed.
Note: A setting of 0.00 will disable the acceleration rate switch that occurs at the end
of Dwell 2.
Default: 0.00%
Min: 0.00%
Max: 100.00%
