Reference Origin Return Bits
These bits can be turned ON to move to the origin of the reference coordinate
system using PTP control. The high-speed feed rate, acceleration time, and
deceleration time are used during the operation.
The override (0.1% to 100.0%) are effective for the manual origin return. An
error will occur if a Reference Origin Return Bit is turned ON but the mechani-
cal origin hasn’t been established. For axes set to the Unlimited Feed Mode,
however, the reference origin will be returned to even if the origin has not
been established.
The bit is ignored if the Busy Flag is ON.
Keep the bit ON until the Reference Origin Flag turns ON.
