reach the maximum speed for a particular profile (unable to reach contract speed
under normal operation). A physical oscilloscope may be required to see this transi-
tion properly. Adjust the Lag delay until the vertical discontinuity is eliminated (see
Figure 2.14).

3. Depending on the tuning of the drive, the leveling distance may have to be generous to
allow the elevator’s speed to completely transition to the requested leveling speed.
• For initial setup, set the Leveling distance parameter to 2.0 inches on the control-
ler’s Configuration > Pattern > Common > Leveling. Once the drive is tuned, this
parameter may be adjusted to a more optimum value.
4. Depending on the tuning of the drive, the transition from leveling speed to zero speed
may be sluggish.
• For initial setup, set the Normal rate limited stop parameter to 7.0 ft/s
