Option/Inv Function Input Status
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:
Option/Inv Function Input Status
IMPORTANT
Function: Auto Mode Sel
Setting: 6D
Function: Hand Mode Sel
Setting: 6E
The 6E setting for digital input defines the speed command (or setpoint) source as the keypad/operator for a closed contact and
allows b1-01 to determine the speed command source for an open contact.
Input Contact Status
This effects the speed command (reference) input only. The Auto Mode Selection (H1-0x=6D) and the Hand Mode Selection
(H1-0x-6E) allows use of a digital input to toggle between the Auto and Hand operational modes for speed control. The Auto
Mode Selection and Hand Mode Selection cannot both be programmed simultaneously. If both 6D and 6E are programmed
together, an OPE03 fault will occur.
