Note) The assignments of dedicated
input/output port functions (such
as RDY output start signal) reflect
the factory settings.
When the READY signal (Output port No.
301) 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 port
Nos. 16 through 22).
Input a start signal (input port No. 0) from the
external device.
If the optional panel unit is connected, the
CODE display area indicates the program
number of each program that has been
started.
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.)
