@IFEED
892 IFEED(892) uses an input interrupt as a trigger to switch from
speed control to position control and move the specified number of
pulses.
(IFEED(892) is supported only by the CJ2M.)

STEP 008 STEP(008) functions in following 2 ways, depending on its position
and whether or not a control bit has been specified.
(1) Starts a specific step.
(2) Ends the step programming area (i.e., step execution).
The step program area is from the first STEP(008) instruction
(which always takes a control bit) to the last STEP(008) instruction
(which never takes a control bit).
Output Required
STEP START SNXT 009 SNXT(009) is used in the following three ways:
(1) To start step programming execution.
(2) To proceed to the next step control bit.
(3) To end step programming execution.
