Precautions When a Canon Laser Rotary
Encoder Is Installed into Another Device
1. Maximum Load on the Shaft and
Coupling When a rotary encoder is connected to the
drive shaft of another device, any sliding of the
shaft core, vibration of the drive shaft, or a thrust
change would affect the bearing that receives the
force, resulting in a decreased level of precision,
shorter life, and/or damage. Please use the unit within
the maximum load.
If the unit is used with rigid connection, the centering
offset and thrust change must not exceed 2mm and 1mm,
respectively. If precise centering is difficult, use
flexible coupling to absorb the centering offset,
contact with the drive shaft, and thrust changes.
Flexible coupling works well in a still state (at
rest) even if the
load due to eccentricity and/or tilting of the drive
shaft exceeds the maximum limit; however, care must
be taken during rotation as an unreasonable amount
of force may cause damage.
2. Effects of Noise from Peripheral Devices Pulse-type
noises generated by motors, motor drivers, power supplies,
relays, and other devices could cause adverse effects
on the encoder, resulting in malfunctioning. In particular,
common- mode (same phase) noise could affect the unit
through the
motor, encoder itself, power-supply line, and shield
lines; therefore, measures must be taken with full
understanding of the path of the electric current.
Here is an example to reduce the effects of the noise.
