Part 2 Operation
2. Starting via External Signal Selection
(1) Flow chart
When the READY signal turns ON, the RDY
lamp (green) on the controller front panel will
illuminate.
Input a desired program number as a BCD code
from the external device.*
Input a start signal from the external device.
When the program is run, the number of the
started program will be shown in the CODE
display area of the controller front panel.
If an emergency-stop signal was input from the
external device or a controller error occurred,
the controller will turn off the servo power (the
RDY lamp will turn off).
*1 You can input program numbers as binary
codes by setting I/O parameter 30 (input
function selection 000) to “2.” (This
parameter has been set to “1,” or BCD code
specification, at the factory.)
Note: On a controller with increased memory size (with gateway function), up to 128 programs can be
stored. Take note, however, that only program Nos. 1 to 79 can be started by BCD code
specification. To start program Nos. 80 to 128 using BCD codes, use the auto program start
function or program start command “EXPG.”
Select a desired program number externally and then input a start signal.
