Mitsubishi FR-A800

(M) Monitor display and monitor output signal
PARAMETERS

GROUP
M
• Terminal CA output [mA] = 20 [mA]  (analog remote output value - 1000)/100
Where the output range is 0 to 20 mA.
• When Pr.158 AM terminal function selection = "87, 88, 89, or 90", an analog voltage can be output from the terminal AM.
• Terminal AM output [V] = 10 [V]  (analog remote output value - 1000)/100
The output range is -10 V to +10 V regardless of the Pr.290 Monitor negative output selection setting.
Analog remote output data retention (Pr.655)
NOTE
• When Pr.655 = "1 or 11" (remote analog output data retention at power OFF), take measures such as connecting R1/L11 with
P/+, and S1/L21 with N/- so that the control power is retained (While power is supplied to R/L1, S/L2 and T/L3). If the control
power is not retained, the analog output after turning ON the power 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.

• 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 analog remote output data is
saved in EEPROM before the power supply is turned OFF.
This means that the analog value output after power
restoration is the same as before the power supply was
turned OFF. However, when Pr.655 = "1", the data is not
saved during an inverter reset (terminal reset, reset request
via communication).
• When Pr.655 = "10 or 11", the analog output before the reset
is saved 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%).
