(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 encoder back up is built-in the drive unit. (An external battery is available as an option.)
(Note 4) The main circuit ( ◎ ) and control circuit ( ○ ) and ground ( ● ) are safely separated.
(Note 5) Connect the ground of the motor to the ground of the connected drive unit.
