3.15. ELEVATION MOTOR DRIVE

3.15.1. M
ECHANICS
The machine incline is varied by moving a frame connected to the front wheels by means of the
elevation motor rod. The motor movement is detected by a hall sensor which provides the motor
motion control signal: each motor revolution generates a predetermined number of pulses and
produces a known displacement of the rod and hence of the machine incline. The direction of
rotation of the motor determines whether the machine moves up or down.

ONTROL
The control block diagram is as follows:

switch
To actuate the motor, the CPU Board communicates via the RS-485 serial link with the ALE Drive.
Depending on the commands received, the Drive sends a +24 or -24Vdc power supply to the Up-
Down motor and in this way determines whether the actuator rod moves in our out. When the motor
receives the voltage it begins to move.
