Caution for using
This unit consists of precision components. If you drop this unit, it may lose the function.
Please treat this product carefully.
When you install this unit, if eccentricity and deflection angle are larger, load is applied to the
shaft. It may shorten the life cycle of this unit.
Do not put strong impact with hammer, etc when insert coupling into shaft.
2. For using
Please use attached Sil Twist pair wire and use proper receiver for RS-422A communication.
Do not cut or connect circuit when power is ON. It may cause damage to the unit.
When the power source is Switching Power, it may cause surge. Install a surge absorber in
power line. Wire should be shorter in order not to be influenced by noise.
Please do not use this unit with below environment, or it may cause malfunction.
Place where this unit or component may be damaged by strong vibration or impact.
Place where there is a lot of flammable or corrosive gases.
Place where strong magnet field or electric noise occurs.
Place where is beyond of the rated temperature or humidity.
Place where strong acids or alkali near by.
Place where there is the direct ray of the sun.
4. Vibration and Impact
If a big impact or strong vibration applies to the product it may cause pulse errors. Be sure that
when installing this unit.
Encoder with high resolution can be easily affected by vibration, therefore tighten fixing bracket
when installing this unit.
5. Wire connection
Do not pull out the wire with over 30N strength after fixing the unit and wiring the cable.
If wire encoder cable with high voltage line or power cable in the same conduit, it may cause a
malfunction or mechanical problem. Please wire it separately or use separated conduit.
