Hollow encoder fault solution

Hollow encoder failure solution article source: release time: 2019/04/28 hits: hollow encoder for its hollow type design advantages attract everybody, hollow design requirements of the diversified design allows designers, widely used in car audio, car air conditioning, car navigation, power amplifier stereo, household appliances and so on. But empty of encoder failure, please pay attention to the solution. A loose, hollow encoder installation: at this time will affect the position control accuracy, stop and moving position deviation value super bad, or even just a boot servo system overload alarm occurs, the pay special attention to. Second, hollow encoder + 5 v power down: refers to the + 5 v power supply is too low, usually cannot be less than 4. 75 v, is the cause of low power supply failure or power transmission cable resistance caused by the big loss, then need to repair the power supply or replace the cable. Three, hollow encoder connection cable fault: has the highest probability, the problem often encountered when maintenance, the failure is to check the priority consideration. General phenomenon is short circuit or poor contact, hollow encoder cable circuit, then should replace the connector or cable. Four, itself fault: refers to the hollow components failure, encoder itself cause itself does not produce hollow encoder and the output waveform. At this time the need to change or hollow encoder internal device maintenance hollow encoder. Five, the grating pollution: it makes the amplitude of signal output, must use absorbent cotton to gently wipe grease anhydrous alcohol. Six, absolute encoder hollow battery voltage drop: this kind of failure is often have clear alarm, and the need to replace the battery, if the reference point position memory loss, still must perform to return to the reference point operations. Seven, hollow encoder cable shielding wire did not pick up or fall off, this kind of circumstance can introduce interference signal, the waveform is not stable, affect the accuracy of the communication, must ensure that the shielding wire reliable welding and grounded. Shanghai electronics co. , LTD is a professional sensor systems and accessories complete service supplier. Company are production and agent products: pull on the rope encoder, hollow encoder and rotary encoder, the magnetic grid ruler, close to switches, photoelectric sensor, the magnetostrictive displacement sensor, obliquity sensor, rope displacement sensor, speed switch, speed motor, reducer, coupling, pulley, chain, cables, controllers and related products, such as near welcome the choose and buy.
