Note
1) The detector uses a 2048 P/R incremental encoder.
2) The keyway complies with JIS B 1301-1976 (precision). A straight key is supplied (types
with key only).
3) The allowable load is applied to the shaft end.
4) The electromagnetic brake is only to hold the load in position and cannot be used to stop
the motor.
