Execute hold/advance operation while making sure the step No. in the
“step No. monitor” parameter (level 0 mode).
•
When the “hold” parameter (level 0 mode) is set to “ : ON”, step
time counting is paused (held), and the HOLD LED lights. [ ] and
the SP appear alternately on the No.2 display when in the “PV/Pres-
ent SP” parameter.
•
Hold is canceled time counting is restarted by one of the following
conditions: “hold” parameter = “
: OFF”, Run, Reset, End opera-
tion using advance instruction
•
Each time that “advance” parameter (level 0 mode) is set to “ :
ON”, the program advances one step. With each step advance, the
“Advance” parameter setting returns to “
: OFF”.
•
If the advance function is executed with the program in a hold state,
the hold state is continued in the next step.
