This range of machines is very broad , using between 2 and 7 DC motors. The controller uses an universal display and central processor, and between 1 and 4 VD203 modules for motor control
Some of the motors perform limited range motions, like lifting and lowering a metal frame. An innovative approach to driving such motors was to limit and sense the motor current, so as upon reaching end position the motor could be turned off without using mechanical switches.
