AIN / S7
Analog or digital
- AIN Analog: When terminal 10 is used as an analog input refer to
parameters F15 (017 & 018), F16 (000-001), F17, F18, F19 (000-001)
and F20 (000-001).
- S7 Digital: When terminal 10 is used as a digital input, parameters
described for multi – function digital input terminals S1 – S4 apply.
NOTE : Logic level high; => +8V* logic level low level; =< 2V
*Caution! Do not exceed 10V maximum.
