during
operation
PLS2 can be executed
during a speed control
operation started with
ACC to change to position-
ing operation.
An error will occur if a con-
stant speed cannot be
achieved after switching
the mode. If this happens,
the instruction execution
will be ignored and the
previous operation will be
continued.

When an interrupt input
occurs during speed con-
trol for the IFEED instruc-
tion, operation changes to
positioning. An interrupt
task is not used.
There is no delay for the
starting time of the inter-
rupt task, improving the
feeding accuracy.
