2. Perform test inspection runs in the down direction at the top of the hoistway while
adjusting the torque scaling value until the torque is just high enough to eliminate
rollback.
NOTE: The pretorque scaling ranges from +127 to -128. See Torque Scaling.
If the user continues to increase the number past +127, the number goes to -128.
3. Place the car at the bottom landing with a full load in the car.
4. Perform zero speed and releveling test runs while adjusting the CW percent until the
torque is just enough to prevent rollback. Decreasing the CW percent value will increase
downward pretorque while increasing the CW percent value lowers the downward
pretorque.
5. Perform the same zero speed and releveling test runs at various floors to verify ride
quality.
6. Calibration is complete.
