Mitsubishi Electric FR-F800 Series Instruction Manual page 346

NOTE
• When Pr.655 = "1 or 11" (remote output data retained at power OFF), take measures to keep the control circuit power ON,
such as connecting terminal R1/L11 with terminal P/+ and connecting terminal S1/L21 with terminal N/- (while power is
supplied via input terminals R/L1, S/L2 and T/L3). If the control power is not retained, the output signal after the inverter power
turns ON is not guaranteed to work. When connecting the high power factor converter FR-HC2, assign the instantaneous
power failure detection (X11) signal to an input terminal to input the IPF signal from the FR-HC2 to the terminal for X11 signal.
Parameters referred to
Pr.54 FM/CA terminal function
Pr.158 AM terminal function
Pr.290 Monitor negative output
Pr.291 Pulse train I/O
5.8.12 Fault code output selection
When a fault occurs, the corresponding data can be output as a 4-bit digital signal using via an open collector output terminal.
The fault code can be read using an input module of programmable controller, etc.

Fault code output selection
M510
• Fault codes can be output to the output terminals by setting Pr.76 Fault code output selection = "1 or 2".
• When the setting is "2", a fault code is only output when a fault occurs. In normal operation the terminal outputs the signal
assigned in Pr.191 to Pr.194 (output terminal function selection).
• The fault codes that can be output are shown in the following table. (0: Output transistor OFF, 1: Output transistor ON)

*1 When Pr.76 = "2", the terminal outputs the signal assigned by Pr.191 to Pr.194.
NOTE
• If an error occurs while Pr.76 ≠ "0", the output terminals SU, IPF, OL, and FU output the signals in the table above regardless
of the settings in Pr.191 to Pr.194 (Output terminal function selection). Take caution when controlling the inverter with the
output signals set by Pr.191 to Pr.194.
