5 External Input/Output Function
45
No. 99MBC109B
Tips
• To enable this function, select the set value 2 (BCD output) of parameter number 20
(tolerance/BCD output mode switching).
• It is possible to invert the SIGN/BANK/PEAK/DATA output logic by setting parameter
number 21 (logic selection) to 1 (H).
• For details about the timing chart, see "5.5.4 Timing Chart" (page 46).

Analog output
Movement of the spindle of a Linear Gage can be monitored as linear voltage by
measuring the voltage between terminals with a pen recorder or oscilloscope.
INPUT A: Pin numbers 22–24
INPUT B: Pin numbers 23–24

5.5.3 Input Function
With an external signal input, you can switch the BANK, switch Peak mode,
activate the Preset function, clear the peak value, set the memory, and clear the
memory. You can also activate a HOLD on the counter values of INPUT A and
INPUT B either separately or simultaneously.
