8.1 Switchable Motion Commands
8.1.7 Switching from FEED
Switched From
FEED
8-18
Switched To
FEED will switch to ZRET when the axis stops after deceleration.
ZRET
FEED will immediately switch to INTERPOLATE, and the moving amount stored in the
accel/decel 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 FEED 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 distribution 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).)

Distribiution will start from the state Speed = 0
since the accel/decel filter is empty.
The accel/decel filter for FEED command will be
