Symbol/Operand
IFEED(892) uses an input interrupt as a trigger to switch from
!FEED(892)
speed control to position control and move the specified number of
pulses.
P
(IFEED(892) is supported only by the CJ2M.)
C
S
P: Port specifier
C: Control data
S: 1st word of
setting table
Symbol/Operand
STEP(008) functions in following 2 ways, depending on its position
STEP(008)
and whether or not a control bit has been specified.
B
(1) Starts a specific step.
(2) Ends the step programming area (i.e., step execution).
B: Bit
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).
SNXT(009) is used in the following three ways:
SNXT(009)
(1) To start step programming execution.
B
(2) To proceed to the next step control bit.
B: Bit
(3) To end step programming execution.
