The installation

Do not apply direct impact to the shaft during installation.

The encoder shaft shall be connected to the machine with a flexible connector.When mounting connectors on the shaft, do not force them in.Even if the use of connectors, due to poor installation, it is possible to add more than the allowable load to the shaft load, or cause the phenomenon of core pulling, therefore, to pay special attention.

Bearing life and service conditions are related to the bearing load is particularly affected.If the bearing load is smaller than the specified load, the bearing life can be greatly extended.

Do not disassemble the rotary encoder, this will damage the oil and drip-proof performance.Drip - proof products should not be long - term immersion in water, oil, water, oil on the surface should be wiped clean.

vibration

The vibration applied to the rotary encoder is often the cause of the false pulse.Accordingly, should install place, installation place to pay attention to.The more pulses per revolution, the narrower the slot spacing of the rotating slot disk, and the more susceptible to vibration.When rotating or stopping at low speed, the vibration added on the shaft or the body makes the rotating slot disk shake, and false pulse may occur.

About wiring and connections

Improper wiring may damage the internal loop, so full attention should be paid to:

Wiring should be carried out under the state of power OFF. When the power is connected, if the output line contacts the power, it will sometimes damage the output loop.

If wiring errors, sometimes damage the internal loop, so wiring should pay full attention to the polarity of the power supply.

If and high - voltage line, power line parallel wiring, sometimes will be induced by the fault into damage, so to separate separate wiring.

When extending the wire, it should be below 10m.And because of the distribution capacity of the wire, the rise and fall time of the waveform will be longer, when there is a problem, schmidt loop is used to shape the waveform.

In order to avoid inductive noise, etc., try to use the shortest distance wiring.Special attention should be paid to the input to the IC.

When the wire is extended, due to the influence of conductor resistance and capacitance between lines, the rise and fall time of waveform is lengthened, which is easy to produce interference between signals (crosstalk). Therefore, the wire with small resistance and low capacitance between lines (twisted pair and shielded line) is applied.

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