Sensors used in motion control and automation systems must have high reliability for the overall performance of the system to be good. Even the most expensive high-resolution sensor will not perform properly if it is installed incorrectly. Proper installation of the sensor is therefore as important as its proper selection and sizing.
Errors made in mechanical assembly and electrical connections give rise to many adverse repercussions. Mechanical distortion produces undue strain on the bearing units, while badly laid out cabling is responsible for the electromagnetic interference. Therefore, the system experiences constant digital signal distortion, uncontrolled jitter, zero-point shifting, and early malfunction of devices.
According to service experience, in most cases, engineers find either a hardware failure or sensor breakdown to be the cause of a breakdown due to installation failures. In particular, all failures occur because of the shaft alignment tolerance violation, fastening bolts under-tightened or overtightened, grounding resulting in closed ground loops, and mistakes in designing couplings.
Today we will discuss:
