Switched To
EX_POSING will immediately switch to INTERPOLATE. The moving amount stored in
the accel/decel filter will be reset to 0.
The value of Position Reference Setting (OL1C) when the motion command is
switched will be as follows.
<In Incremental Addition Mode (OW09, bit 5 = 0)>
Incremental value = Position incremental value per high-speed scan
OL1C = OL1C + Incremental value
<In Absolute Mode (OW09, bit 5 = 1)>
OL1C = IL14 (DPOS) + Position incremental value per high-speed scan
 INTERPOLATE switched from EX_POSING starts its operation with the
empty accel/decel filter. Therefore, when the accel/decel filter is set for
INTERPOLATE command, the speed will not smoothly change, and the distri-
bution will be started from the state Speed = 0 (see (1).) To change the speed
smoothly, do not set the filter for INTERPOLATE command (see (2).)

until it reaches the FEED target speed.
The accel/decel filter will remain valid.
