Analog inputs received on the Machine operator’s panel interface unit are
converted to five–bit digital values, which are sent to the CNC though the
I/O Link.
See Subsec. 6.7.5 for PMC addresses.
LM conversion data : “LM03 to LM07”
SM conversion data : “SM03 to SM07”
Acceptable input voltage 0V to +15V
Voltage that can be converted to digital 0V to +10V Note)
NOTE
Any voltage higher than +10V is converted to the same
digital value as +10V is.
Conversion error 5% (max)
Resolution 5 bit (min)
