Basic Return-to-origin Operation
The return-to-origin operation is started when the RUN command is input with multifunction input ter-
minal “SPD” set to OFF and terminal “ORG” set to ON. Specify the operation direction in Homing Op-
eration Selection (d209). The return-to-origin operation is as follows. Acceleration is performed to the
frequency set in Homing Frequency/Orientation Frequency (d213), and, after the moving body has
turned origin search limit signal “ORL” ON, movement is performed from the initial Z phase signal (ref-
erence signal for homing of
fset) by the amounts set in the homing offsets (Homing Of
fset (MSB)
(d242) and Homing Offset (LSB) (d243)), and movement is stopped. The positioning completed signal
“POK” also is output. When overtravel turns ON before the origin limit switch, reverse rotation opera-
tion is performed to search for the origin limit switch.
