Encoder failure: it refers to the failure of the encoder's own components, causing it to fail to generate and output the correct waveform. In this case, you need to replace the encoder or repair its internal components.
Encoder connection cable failure: This type of failure has the highest probability and is often encountered during maintenance and should be a priority factor. Usually the encoder cable is open, short-circuited or poorly contacted. At this time, the cable or connector needs to be replaced. Special attention should also be paid to whether the cable is not tightly fixed, causing loosening or disconnection. At this time, the cable needs to be clamped.
Encoder +5V power supply drop: refers to the +5V power supply is too low, usually not lower than 4.75V, the cause of the too low is the power supply failure or the power transmission cable resistance is too large and cause loss, then the power supply needs to be repaired or replaced cable.
Absolute Encoder battery voltage drops: This type of failure usually has a clear alarm. At this time, the battery needs to be replaced. If the reference point position memory is lost, the reference point must be returned.
Encoder cable shield wire is not connected or falls off: This will introduce interference signals, make the waveform unstable, and affect the accuracy of communication. It is necessary to ensure reliable welding and grounding of the shield wire.
Loose encoder installation: This kind of failure will affect the accuracy of position control, resulting in excessive position deviation during stop and movement, and even generate servo system overload alarms immediately after starting up. Please pay special attention.
Grating pollution This will reduce the signal output amplitude, so you must use absorbent cotton dipped in absolute alcohol to gently wipe off the oil.
