Setting Up Performance Curves
Before attempting to bring the car up to contract speed, you must have verified drive parame-
ters as described in Section 2. Torqmax F5 AC Drive Parameters on page 2-31 or Magnetek AC
Drive Parameters on page 2-36, F7 parameters as described in Section 4, F7: Parameters Adjust
on page 4-118, and be successfully running on Inspection mode with all equipment installed.
Performance curves are defined by acceleration and deceleration rates. The top speed attained
using a curve is defined by speed settings for a particular mode of operation (Contract Speed,
Inspection Speed, etc.). Multiple speed settings can use the same performance curve. Please
refer to “Controller F7 Menu” on page 3-13.
Acceleration and Deceleration Rates
Acceleration and deceleration rates are measured and programmed in ft/s
2
(feet per second per
second). Jerk parameters adjust the rate of transition from one speed to another and are mea-
sured and programmed in ft/s
3
(feet per second per second per second). F7 control parameters
correspond to curve locations as shown in the following figure. Increasing Jerk values causes
faster change. While adjusting S-Curve parameters, stay away from terminal floors.
Figure 3.1 Motion 4000 Performance Curves
Curves Used for Operating Speeds
The performance curves shown above and the operating speeds that use them are:
• Standard Curve: Contract, correction, earthquake, and leveling speed
• Alternate Curve: Conservation, and emergency power speed
• Manual Curve: Inspection and reduced inspection speed
• Danger “Curve”: Used for emergency deceleration
