7.1.
Relationship between parallel type input signal and control
pressure
The parallel type input signal is 10 bit width. The signal ranges from 0 to 1023 when converted into a
decimal.
Input signal = ER set pressure (Bar) / Max. control pressure (Bar) × 1023
Max. control pressure ER104-5: 5 Bar
ER104-9: 9 Bar
Example: In the case of setting 3 Bar to ER104-5xxx.

The inverse operation with “614” is:

“614” (decimal) converted into a binary is 1001100110. Turn the input signal on at “1” and turn it off at
“0.” (See the table below.)
