Some common problems with the encoders of glass tempering furnace

1. Encoder malfunction:

The encoder's components have malfunctioned, resulting in its inability to generate and output correct wave forms. In this case, it is necessary to replace the encoder or repair its internal components.

2. Encoder connection cable fault:

The probability of this type of malfunction occurring is relatively high, and it is often encountered during maintenance. During inspection, the engineer should pay more attention on this fault which happens time by time. Usually, it is due to an open circuit, short circuit, or poor contact in the encoder cable. At this point, pls replace the cables or connectors. In addition, special attention should also be paid to whether the loose cable fixation caused the circuit breaker, in which case the cable needs to be tightened.

3. Encoder+5V power supply drops:

This problem refers to the low voltage of the+5V power supply, which usually cannot be lower than 4.75V. The cause of the low voltage should be a power supply failure or a loss caused by the high resistance of the power transmission cable. In this case, it is necessary to repair the power supply or replace the wires.

4. Absolute encoder battery voltage drop:

This type of fault usually has a clear alarm, in which case the battery needs to be replaced. If the reference point position memory is lost, a return to the reference point operation needs to be performed.

5. Encoder cable shielding wire not connected or detached:

This can cause interference signals, make the waveform unstable, and affect the accuracy of communication. It is necessary to ensure reliable welding and grounding of the shielding wire.

6. Loose encoder installation:

This type of fault can affect the accuracy of position control, causing excessive position deviation during stopping and moving, and even generating servo system overload alarms upon startup. Please pay special attention.

7. Grating contamination:

This will cause a decrease in signal output amplitude. Please gently wipe off the oil stains with a degreased cotton dipped in anhydrous alcohol.
