4.4 Changing the Command
4.4.2 Operation after Changing the Motion Command
4-148
EX_POSING
ZRET
The motion command immediately switches to the ZRET command, and
the travel distance that is stored in the acceleration/deceleration filter is
continued.
Precautions
The speed may decrease because the related parameters are written at the
start of ZRET execution.
INTERPOLATE
The motion command switches to the INTERPOLATE command after the
axis decelerates to a complete stop.
Changing OL1C (Position Reference Setting) during Deceleration
• Using the Incremental Value Addition Method (When Bit 5 in OW09
Is Set to 0)
Any change to OL1C (Position Reference Setting) is ignored.
• Using the Absolute Value Specification Method (When Bit 5 in
OW09 Is Set to 1)
The change to OL1C (Position Reference Setting) is output in the
first high-speed scan after execution of the INTERPOLATE command is
started.
Precautions
Do not change the Position Reference Setting parameter during decelera-
tion.
LATCH Same as the INTERPOLATE command.

The speeds will change smoothly.
(Acceleration or deceleration is performed
to the target speed of the ZRET
command based on the current speed
when the command was switched.)
The acceleration/deceleration lter also
continues operation.
