When bit 03 is OFF (i.e., Program Mode), bits 04 to 15 are enabled for the Posi-
tion Control Unit. The NC113 is provided with the X axis only. Bits 10 to 14 will be
ignored by the NC113.
Note When the CPU Unit is in either Run or Monitor Mode, bit 03 must be turned ON by
the program. When bit 03 is OFF, commands cannot be received by means of
WRIT (the Intelligent I/O Write instruction).
Ladder Program Example
If bit 03 is turned ON by a forced set when the CPU Unit is in Program Mode, the
Position Control Unit will stop all operations in Program Mode.
