Monitor switching

Used to reset fault output provided when a fault occurs.

Turn ON the RES signal for more than 0.1s, then turn it OFF.

Turning ON the SOF signal stops the converter.

RDY signal turns OFF, limit MC turns ON

200V class

7.5K to 75K

400V class

Connect this terminal to terminal ROH1 of the outside box (FR-HCB2). The ROH signal is input to stop the converter operation when the limit resistor may overheat.

400V class

280K to 560K

An auxiliary contact (NO contact) of a limit resistor MC, a limit resistor (with thermostat)

(NC contact), and a filter capacitor alarm detector (NC contact, 400K, 560K) are connected to stop the converter operation when overheating of the limit resistor becomes a concern and when a filter capacitor is faulty.

FM and AM output or PU monitor display can be switched by a combination of ON/OFF of X1 signal and X2 signal.

Analog signal output

Output item: PHS signal (power phase detection) (initial setting)

Turns ON when power phase detection is locked.

Turns ON at a converter reset (RES-ON).

Connect this terminal to the inverter terminal of which RES signal is assigned to.

Reset the connected inverter by turning ON the RSO.

Common terminal for the terminals RDY, CVO, OL, Y1, Y2

Connect it to the inverter terminal SD (sink logic).

Select one monitor item from multiple monitor items such as input current and bus voltage. Not output during a converter reset.

The output signal is proportional to the magnitude of the corresponding monitoring item.

Monitor item can be switched by ON/OFF of terminals X1 and

X2.

Analog signal output common

Common terminal for analog signal output

Fault contact

1 changeover contact output indicates that the converter's protective function is activated and the output is stopped.
