Programming 5 - 52
To switch the command source between the serial communication port and the control circuit terminals be sure to program the
following parameters:
•
Set b1-01 (Frequency Reference Selection) to 1 (Terminals).
•
Set b1-02 (Run Command Selection) to 1 (Terminals).
•
Set H1-0x (Input Terminal Function Selection) to 6B or 6C.
The Com/Inv Sel 2 function will operate the same way except the logic is reversed. When a digital input is programmed for the
Com/Inv Selection function (H1-0x= 6C) that input will function as follows:
