Note 1) The detector uses an incremental encoder 2048 P/R.
2) Type “A” indicates 200 V specification.
3) “08A314B” and “08A316B” have a keyed shaft. The keyway complies with JIS B
1301-1976 (precision). A straight key is supplied.
4) The quoted allowable radial load is the value at a position 35 mm (1.38 in.) from the mo-
tor mounting surface.
5) The electromagnetic brake is only to hold the load in position and cannot be used to stop
the motor.
