Hengstler encoder common fault description

German HENGSTLER encoder common fault
1. The encoder itself is faulty: it means that the components of the Hengsler HENGSTLER encoder itself are faulty, which causes it to not generate and output the correct waveform. In this case, you need to replace the Huntsman encoder or repair its internal components.
2, encoder connection cable failure: This type of failure has the highest probability of occurrence, often encountered in maintenance, should be a priority factor. Usually the Hensler encoder cable is broken, shorted or poorly connected, in which case the cable or connector needs to be replaced. Special attention should also be paid to whether the cable is not tightly fastened, causing loosening to cause open welding or breaking, and the cable needs to be clamped.
3. Encoder +5V power supply drop: It means that the +5V power supply is too low, usually not lower than 4.75V. The cause of too low is the power supply failure or the power transmission cable resistance is too large, causing loss. Or replace the cable.
4, absolute hengstler encoder battery voltage drop: This type of fault usually has a clear-cut alarm, then you need to replace the battery, if the reference point position memory is lost, you must also perform a re-reference point operation.
5. The shield cable of the encoder cable is not connected or disconnected: this will introduce interference signals, make the waveform unstable, affect the accuracy of communication, and must ensure reliable welding and grounding of the shielded wire.
6. The encoder is loosely installed: this kind of fault will affect the position control accuracy, resulting in the position deviation of the stop and the movement is too poor, even if the servo system overload alarm is generated just after the start, please pay special attention.
7, grating pollution This will cause the signal output amplitude to drop, you must use a cotton wool with absolute alcohol to gently wipe the oil.
