BASIC USES OF Σ-SERIES PRODUCTS
2.2.4 Installing the Servomotor cont.
26
A precision detector (encoder) is mounted on the opposite-drive end of the servomotor.
To mount a coupling, always protect the shaft from impacts that could damage the detec-
tor.
Perform a mechanical design so that thrust load and radial load applied to the servo-
motor shaft end falls within the range given in the following table.

Note Allowable radial loads shown above are the maximum values that could be ap-
plied to the shaft end.
TERMS
Thrust load and radial load
1. Thrust load: Shaft-end load applied parallel to the
centerline of a shaft
