LASER ROTARY ENCODER
Precautions When Installing 
1.Maximum Load on the Shaft and Coupling
When a rotary encoder is connected to the drive shaft 
of anotherdevice, any sliding of the shaft core, 
vibration of the drive shaft,or a thrust change would 
affect the bearing that receives theforce, resulting in a 
decreased level of precision, shorter life,and/or 
damage Please use the unit within the maximum

damage.  Please use the unit within the maximum 
load.If the unit is used with rigid connection, the 
centering offset andthrust change must not exceed 
2mm and 1mm, respectively. Ifprecise centering is 
difficult, use flexible coupling to absorb thecentering 
offset, contact with the drive shaft, and thrust 
changes.Flexible coupling works well in a still state (at 
rest) even if theload due to eccentricity and/or tilting of 
the drive shaft exceedsthe maximum limit; however,

the drive shaft exceedsthe maximum limit; however, 
care must be taken during rotationas an unreasonable 
amount of force may cause damage.
2. Effects of Noise from Peripheral Devices
Pulse-type noises generated by motors, motor drivers, 
powersupplies, relays, and other devices could cause

adverse effectson the encoder, resulting in 
malfunctioning. In particular, com-mon-mode (same 
phase) noise could affect the unit through themotor, 
encoder itself, power-supply line, and shield lines; 
there-fore, measures must be taken with full 
understanding of the pathof the electric current.  Here 
is an example to reduce the effectsof the noise.
