Precautions for installing and using the encoder

Encoder is a kind of precision electronic component, a sensor device that can be used to measure displacement, distance, speed and angle. The encoder can perform functions such as increment, decrement and page turning through cooperation with IC. Encoder applications are mainly used for volume, frequency, temperature, measurement, speed adjustment and menu selection. Today I will tell you about the precautions for installing the encoder and the precautions for using the encoder.

Precautions for installing the encoder

1. The connection problem. Do not apply direct impact to the shaft during installation. The connection between the encoder shaft and the machine should use a flexible adapter. When installing the adapter on the shaft, do not hard press it in. Even if the adapter is used, due to the defective device, it is possible to add a load greater than the allowable load to the shaft, or form the appearance of a core shift. Bearing life is related to operating conditions and is particularly affected by bearing load. Do not disassemble the rotary encoder (electronic handwheel). Doing so will damage the oil and drip-proof functions. Oscillation added to the rotary encoder (encoder selection) will often become the cause of false pulses.

2. Attention should be paid to the installation location and installation location. The more the number of pulses per retransmission, the narrower the slot interval of the rotating slotted disk, and the more susceptible it is to vibration. When rotating or stopping at low speed, the oscillation added to the shaft or the body causes the rotating grooved disk to vibrate, which may cause false pulses.

3. Regarding the wiring and connection, wrong wiring may damage the internal circuit, so you should pay sufficient attention when wiring. The wiring should be carried out in the power OFF state. When the power is turned on, if the output line touches the power supply, sometimes Will damage the output circuit. If the wiring is wrong, the internal circuit may be damaged. Therefore, pay attention to the polarity of the power supply when wiring. In order to prevent induced noise, etc., use the shortest interval wiring possible. Special attention is required when inputting to integrated circuits.

Precautions for the use of encoder

1. The use of through-hole printed circuit boards and non-recommended circuit boards will change due to the influence of thermal stress, so please fully confirm the soldering conditions in advance.

2. With positioning type, please weld at the positioning position. If welding is performed in a state where the positioning midpoint is fixed, the positioning mechanism may be deformed.

Three. Can not be cleaned

4. Regarding vibration, the vibration added to the rotary encoder will often become the cause of false pulses. Therefore, attention should be paid to the installation location and installation location.

5. In the assembly process of assembly parts, pay special attention not to apply external force to small and thin switches.

6. When tightening and installing bolts, it must be carried out within the specified strength. If the specified strength is exceeded, it may cause malfunction or damage to the bolt.

7. If the voltage is below VC1V or the current is below 10UA, there is a possibility of poor contact.

8. If the wiring is closed to the high-voltage line and power line, it will sometimes be induced to cause malfunction and damage, so separate the other wiring.

When there is a potential difference between the housing of the encoder and the control panel box, it may cause malfunction due to noise. In this case, a certain distance between the two is required to connect the wires.
