Speed and Acceleration Control
Motion 4000 generates the performance curve that controls the drive and transfers that infor-
mation to the drive through a serial connection. Speed, acceleration, deceleration, and jerk
parameters are set up through the F7 menu on the controller (HC-MPU board/controller on
Inspection/F7 function switch UP/all other function switches DOWN).
Even though speed and acceleration/deceleration/jerk parameters are determined by Motion
4000 settings, certain drive settings can still have a limiting effect and, if set incorrectly, can
prevent the elevator from reaching commanded speed.
Drive gear ratio, rated RPM, contract speed, roping ratio, and sheave diameter settings dictate
the fastest speed at which the drive will run the motor and must be accurately set on the drive.
In the illustration below, the dashed line labeled DRIVE CLIPPING illustrates what can happen
to the S-curve if drive settings limit commanded speed. Rather than rolling into commanded
speed, the car will drop into a steady speed state abruptly, will run at a less than commanded
speed, and will drop into deceleration abruptly. So, improper drive settings can cause failure to
achieve commanded speed and bumpy transitions at speed/acceleration transition points.
