Important notes on selection

(1) The value indicated for the load assures a life of 5 years, assuming that it operates at the rated rotation speed for 8 hours a day and operates smoothly without impact.
(2) Index absolute type cannot be used during pulse train control and MECHATROLINK III/EtherCAT motion/SSCNET control.
(3) Please note that only the short cut control is available when using XSEL with index absolute type.
(4) High resolution type cannot be connected to XSEL-P/Q.
(5) Safety measures may be required depending on the attachment orientation. Refer to page 1-261 for further details.

Homing method and forward rotation direction

When viewed from the top of the rotating part, the clockwise rotation is the forward (+) direction.

Rotates clockwise during a homing.

Detects and stops at the home position.

This product supports different types of operation and resolutions depending on the controller connected. Please check the items supported by each controller before using them.

(Note 7) When the index absolute type of XSEL moves 180 degrees or more from the current position, it rotates in the direction with less movement amount to move to the target position. Therefore, please note that the direction of rotation changes depending on the current position and the amount of movement.

(Note 8) The index absolute type can rotate infinitely in the same direction. However, the maximum amount of movement of XSEL at one time is 180 degrees. It cannot rotate continuously in the same direction without stopping like how a motor does.

The travel time varies depending on the load inertia. Please check the estimated travel time from the table below.

(Note) The numbers indicated in the table are just the guidelines and does not guarantee the travel time.

(Note) The time indicated in the table is the time from receiving the move command to converging to the positioning width of 0.028 degrees (about 100 angle seconds).
