Fault Code Output Selection - Mitsubishi Electric FR-A800 Series Instruction Manual

• When Pr.158 AM terminal function selection = "87, 88, 89, or 90", an analog voltage can be output via terminal AM.
• Terminal AM output [V] = 10 [V] × (Analog remote output value - 1000)/100
The output range is -10 to +10 V regardless of the Pr.290 Monitor negative output selection setting.

 Analog remote output data retention (Pr.655)
• When the power supply is reset (including a power failure) while Pr.655 Analog remote output selection = "0" (initial
value) or 10" and, the remote analog output (Pr.656 to Pr.659) returns to its initial value (1000%).
• When Pr.655 = "1 or 11", the remote output data is stored in EEPROM before the inverter power is turned OFF. This means
that the signal output setting after power restoration is the same as that before the power was turned OFF. However, when
Pr.655 = "1", the data during an inverter reset (terminal reset or reset request via communication) is not saved.
• When Pr.655 = "10 or 11", the remote output data in the signal before the reset is stored even during an inverter reset.
• When the setting in Pr.655 is changed, the remote analog output (Pr.656 to Pr.659) returns to its initial value (1000%).

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.

5.11.12 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.
