(Note 1) The total length of the optical communication cable from the NC must be within 30m and the
minimum-bending radius within 80mm.
(Note 2) The connection method will differ according to the used motor.
(Note 3) Battery for the detector back up is built-in the drive unit. (An external battery is available as an
option.)
(Note 4) The main circuit ( ) and control circuit ( ) are safely separated.
