4.10 Function assignment of external terminal and control
4.10.1 Input terminal function selection (Pr. 178 to Pr. 189)
The above parameters can be set when Pr. 160 User group read selection = "0". (Refer to page 190)
....Specifications differ according to the date assembled. Refer to page 400 to check the SERIAL number.
(1) Input terminal function assignment
