摘要

An electronic control unit (50) is provided with a micro-processor to control the motor (38) and the reversible motor (40) at least determines the end positions of the movement tracks. An overheating of the motors leads to automatic shut-off, and electric interference causing the microprocessor program to crash automatically causes an inbuilt RESET routine to take control. The DC motors (38, 40) with their associated drives (36; 42-44) and the electronic control unit (50) are accommodated in a common housing (11), made of plastic material or aluminium. ADVANTAGE - Simple drive producing low noise level. Motors operate at low voltage e.g. 24 v.
