The encoder installation considerations

(1) the installation

Don't give axis exert direct impact during installation.

Encoder shaft connected to the machine, you should use the flexible connector. In a shaft connector, don't press hard into the. Even if the use of connectors, because bad installation, may also be added to the axis of is greater than the permissible load load, or dial the core phenomenon, therefore, pay special attention to.

Bearing life related to the conditions of use, affected by the bearing load of extremely large. Such as bearing load ratio regulation load is small, can greatly extend the life of the bearing.

Don't disassemble rotary encoder, doing so will hurt oil and drip proof performance. Drip-proof type product is unfavorable and long-term immersion in water, oil, when the surface of water, oil should be wiped clean.

(2) vibration

Add in the vibration on the rotary encoder, can become false pulse. Therefore, to set the place, the installation place. The more the number of pulses per revolution happened, the narrower the rotating slots of the disk slot interval, the more susceptible to the effect of vibration. In low-speed rotation or stops, and spin groove on the shaft or the ontology of vibration disc jitter, pulse error may occur.

(3) about the wiring and connections

False wiring, it might damage the internal loop, therefore when wiring should take note:

1) wiring shall be carried out under the power OFF state, when power on, if the power supply output line contact, sometimes will damage output circuit.

(2) if the wiring error, sometimes will damage the internal circuit, so the wiring should take note the polarity of the power supply, etc.

If parallel wiring and high tension line, power line, sometimes is induced into damage caused by misoperation, so let's separate wiring separately.

(4) extension cord, should be under 10 m. And because the wire and the distribution of capacity, waveform of rising and falling time is longer, there is a problem, use schmidt circuit of waveform shaping, etc.

(5) in order to avoid induced noise, etc., to use the shortest distance wiring. To the integrated circuit input, need special attention.

6 wire extension, conductor resistance and the influence of the capacitance of the line, the waveform of rising and falling time lengthen, prone to interference between signals (crosstalk), so the application of low resistance small, the line between the capacitance wire (twisted-pair cable, shielded wire).

For HTL with symmetric negative signal output of the encoder, the signal transmission distance up to 300 meters
