- Installation Caution
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.
Maximum Load
| Model | Radial | Thrust |
| R-1 · K-1 | 0.4kg | 1.0kg |
| M-1 | 1.5kg | 2.0kg |
Application Example (R-1): To attain a transfer precision of 10 seconds with U-2 type coupling (manufactured by Daido Seimitsu Kogyo K.K.):
The mounting eccentricity shall be within 0.03mm.
