Inspection Speed (Reduced), 156
If the car reduces inspection speed upon
encountering normal or emergency terminal speed switches, enter that reduced speed here.
Correction Speed, 157
If the car should lose position, this is the speed at which it will
proceed to a known point to re-establish position. Default is 75 FPM.
Leveling Speed, 158
Leveling speed is the speed the car uses when initially leveling
into the door zone. Default is 4 FPM.
Re-Leveling Speed, 159
Should the car not level properly initially and require re-lev-
eling, this is the speed that will be used. Default is 6 FPM.
Leveling Distance, 160
This is the distance in inches (above and below) floor level at
which the car should slow to leveling speed. Initially, set to 4.0 inches. After initial tuning, 2.0
inches is generally sufficient.
Re-Leveling Distance, 161
If the car initially levels into the floor above or below this
distance from accurate level, a re-leveling operation will proceed.
Proximity Distance, 162
Determines the distance at which the speed is transitioned
to leveling speed under abnormal conditions like an emergency slowdown.
Leveling Dead Zone Distance, 163
This is the distance from floor level position at
which the stop command is issued during initial leveling and the car “coasts” to a stop. Start
with 0.7 inches.
Standard Start Jerk, 165
Defines the transition from zero speed to full acceleration.
As Start Jerk increases, the profile transitions more quickly from starting to maximum acceler-
ation. Values typically range from 4.0 to 8.0 ft/s
3
(1.219 to 2.438 m/s
3
) with higher values
resulting in a sharper start.
Standard Roll Jerk, 166
Roll Jerk determines how quickly the profile transitions
from maximum to zero acceleration and zero to maximum deceleration. As Roll Jerk increases,
the profile transitions more quickly. Lower values provide greater comfort but are harder to fit
into the shortest one-floor-runs. We recommend that you identify the shortest full height floor
and use it when testing parameter values. Typical values range from a minimum of 4.0 ft.
Standard Stop Jerk, 167
Defines the transition from deceleration to Leveling Speed.
As Stop Jerk increases, the profile transitions more quickly from Deceleration to Leveling
Speed.
Standard Acceleration, 168
Determines the maximum acceleration for the profile.
Determines the maximum current delivered by the AC Drive during acceleration. The maxi-
mum value is typically 4.0 ft/s
2
(1.219 m/s
2
) and the minimum is usually not less than 2.5 ft/s
2
(0.762 m/s
2
). Values higher than 4.0 ft/s
2
(1.219 m/s
2
) are possible but do not yield significant
improvements in performance.
