Switching Operation Mode By External Signal (X16 Signal); Switching The Operation Mode By External Signals (X65, X66 Signals) - Mitsubishi Electric FR-F800 Instruction Manual

Switching operation mode by external signal (X16 signal)
• When External operation and the operation from the operation panel are used together, the PU operation mode and
External operation mode can be switched during a stop (during motor stop, start command OFF) by using the PU-External
operation switchover signal (X16).
• When Pr.79="0", "6" or "7", switching between the PU operation mode and External operation mode is possible. (When
Pr.79="6", the switchover can also be made during operation.)
• To input the X16 signal, set "16" in any of Pr.178 to Pr.189 (input terminal function selection) to assign the function to a
terminal.

NOTE
• The status of the operation mode follows the Pr.340 Communication startup mode selection setting and the ON/OFF state
of the X65 and X66 signals. (For details, refer to
• The priority among 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.
Switching the operation mode by external signals (X65, X66 signals)
• When Pr.79 ="0, 2 or 6", the PU operation mode and External operation modes can be changed to the Network operation
mode during a stop (during motor stop, start command OFF) by the PU/NET operation switchover (X65) signal, the
External/NET operation switchover (X66) signal. (When Pr.79 ="6", switchover is enabled during operation.)
• To switch between the Network operation mode and the PU operation mode
1) Set Pr.79 = "0 (initial value) or 6".
2) Set Pr.340 Communication startup mode selection="10 or 12".
3) Set "65" in any of Pr.178 to Pr.189 to assign the NET-PU operation switching signal(X65) to a terminal.
4) When the X65 signal is ON, the PU operation mode is selected. When the X65 signal is OFF, the Network operation
mode is selected.

When the X66 signal is ON, the NET operation mode is selected.

When the X16 signal is OFF, the PU operation mode is selected. Also, when "0" is set for Pr.550 NET mode operation command source
selection and the communication option is not connected (communication option is the command source), the PU operation mode is selected.
