POINT

(1)Home position shift function is used to rectify a home position stopped by the home position return. When there are physical restrictions in the home position by the relation of a proximity dog installation position, the home position is rectified to the optimal position. Also, by using the home position shift function, it is not necessary to care the zero point for an installation of servomotor.

(2)After proximity dog ON, if the travel value including home position shift amount exceeds the range of “-2147483648 to 2147483647” [10-1µm, 10-5inch,

10-5degree, PLS], “travel value after proximity dog ON” of monitor register is not set correctly.

(4)Torque limit value at the creep speed

(a)Torque limit value at the creep speed (on press) is set in the case of using the pressed position as the home position by the home position return of stopper type 1, 2.

(b)Valid/invalid of the torque limit value at the creep speed by the home position return method is shown below.
