Switching from the INTERPOLATE Motion Command
This section describes the operation when switching to another command during execution of
the INTERPOLATE command.

Operation
INTERPOLATE
NOP
The motion command immediately switches to the NOP command, and the
travel distance that is stored in the acceleration/deceleration filter is distrib-
uted.
POSING
The motion command immediately switches to the POSING command, and
the travel distance that is stored in the acceleration/deceleration filter is
continued.
The value of OL1C (Position Reference Setting) when the motion
command is switched is as follows:
• Using the Incremental Value Addition Method (When Bit 5 in OW09
Is Set to 0)
Incremental value = Target position − IL14 (DPOS)
OL1C = OL1C + Incremental value
• Using the Absolute Value Specification Method (When Bit 5 in
OW09 Is Set to 1)
OL1C = Target position

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