3.23. ELEVATION MOTOR DRIVE
3.23.1. 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.
3.23.2. C
ONTROL
The control block diagram is as follows:
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.
