Mitsubishi FR-A800

(D) Operation command and frequency command
314
PARAMETERS
• To switch between the Network operation mode and the External operation mode
1) Set Pr.79="0" (initial value) or "2, "6" or "7". (When Pr.79 ="7" and the X12 (MRS) signal is ON, the operation mode can
be switched.)
2) Set Pr.340 Communication startup mode selection ="0" (initial value), "1" or "2".
3) Set "66" in one of Pr.178 to Pr.189 to assign the NET-External operation switching signal (X66) to a terminal.
4) When the X66 signal is ON, Network operation mode is selected. When the X66 signal is OFF, the External operation
mode is selected.
 When "Pr.550 NET mode operation command source selection = "0" (communication option control source)" and no communication option is
connected, the External operation mode is selected.
 When the X16 signal is OFF, the PU operation mode is selected. Also, when the X65 signal is assigned, the operation mode follows the ON/OFF
state of the X65 signal.
NOTE
• The priority of Pr.79 and Pr.340 and signals is Pr.79 > X12 > X66 > X65 > X16 > Pr.340.
• Changing the terminal assignment using Pr.178 to Pr.189 (input terminal function selection) may affect the other
functions. Set parameters after confirming the function of each terminal.
