encoder

Precautions for using the encoder:

Problem 1: The power supply capacity of the encoder is small

Insufficient power supply capacity can cause the following situations: the movement of the adhesive will cause the display of the mold closing electronic ruler to change and fluctuate, or the movement of the mold closing will cause the display of the injection electronic ruler to fluctuate, resulting in increased measurement errors. If the power supply for the drive encoder of the solenoid valve is shared, this situation is more likely to occur.

Question 2: Frequency modulation interference and electrostatic interference

Both frequency modulation interference and electrostatic interference have digital fluctuations on the display of an encoder electronic ruler. So, the signal line of the electronic ruler and the strong current line of the equipment should be separated by cable trays. The electronic ruler must be forcibly grounded. The signal line needs to use shielded wire, and a section of the electrical box should be grounded to the shielded wire. If there is high-frequency interference, the voltage measurement using a multimeter usually shows normal, but the displayed number will jump continuously; When static interference occurs, the situation is the same as high-frequency interference. To prove whether it is static interference, simply use a power cord to short-circuit the cover screw of the electronic ruler to some metal on the machine. As long as it is short circuited, the static interference will be immediately eliminated. But if you want to eliminate high-frequency interference, it is difficult to use the above method. You can try pausing the high-frequency interference source to see if the display results will be better, in order to determine whether it is a problem with high-frequency interference.

Question 3: The displayed data jumps regularly or there is no displayed data

If this situation occurs, it is necessary to check whether the insulation of the connecting wire is damaged and whether it is in regular contact with the machine's casing, resulting in a short circuit to ground.

Question 4: What are the requirements for the encoder's neutrality, parallelism, and angle
