FOERFARANDE FOER AVKAENNING AV STEGFOERLUSTER VID STEGMOTORDRIVNA STAELLANORDNINGAR.

摘要

In the method for detecting step losses in stepping-motor-driven actuating devices, a reference position of the actuating device is used for generating a sequence of drive pulses for the stepping motor. Simultaneously, the motor rotation is used for generating a pulse sequence which is compared at the rate of the drive pulses with a pattern, specific to the type of construction, of the stepping motor.
