Sets the motor rated speed.
Slip compensation for leveling speed can be set separately for motoring and
regenerative states. This can help improve the accuracy of leveling.
Sets a delay time before detecting torque for slip compensation.
Sets the filter time constant applied to the torque signal used for the slip compensation
value calculation.
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.
Sets the Position Lock gain at stop. Position Lock at stop keeps the car in position
until the brake has been applied entirely.
Determines the bandwidth around the stop position in which a digital output
programmed for "Within Position Lock Bandwidth" (H2- = 33) is closed.
Sets a time constant for the torque reference to reach 300%. Enabled by setting an
analog input terminal for torque compensation (H3- = 14).
Adds a bias to torque compensation value from the load cell when moving in the
down direction.
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.
Sets the time for torque compensation to diminish once motor speed reaches the level
set in S3-14.
Determines the reduction rate used bring the internal torque reference value down to
zero after Position Lock at Stop has finished.
Torque 300%

S3-16
Sets the speed reference for the Dwell 2 function.
Note: A setting of 0.00 essentially disables the Dwell 2 function.
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.
