2.13 Wiring of control circuit
2.13.1 Description of control circuit terminal
indicates that terminal functions can be selected using Pr. 3 to Pr. 7 (input terminal function selection) and Pr. 11 to Pr. 16
(output terminal function selection)(Refer to page 76, 78)
(1) Input signal

Symbol
Terminal Name Description Rated Specifications
Contact input
RES
Reset
Used to reset fault output provided when a fault occurs.
Turn ON the RES signal for more than 0.1s, then turn it OFF.
Input resistance : 4.7k
Voltage at opening: 21
to 27VDC
Contacts at short-
circuited: 4 to 6mADC
SOF
Converter stop
Turning ON the SOF signal stops the converter.
RDY signal turns OFF, limit MC turns ON
ROH
Inrush current limit
resistor overheat
protection
200V class
7.5K to 75K
400V class
7.5K to 220K
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.
X1
Monitor switching
FM and AM output or PU monitor display can be switched by a
combination of ON/OFF of X1 signal and X2 signal.
X2
SD
Contact input
common
(sink) (initial setting)
Common terminal for contact input terminal (sink logic) and terminal
FM.
External transistor
common (source)
When connecting the transistor output (open collector output), such
as a programmable controller in source logic, connect the external
power supply common for transistor output to this terminal to
prevent a malfunction caused by undesirable currents.
24VDC power supply
common
Common output terminal for 24VDC 0.1A power supply (terminal
PC).
Isolated from terminals 5, SE and SE2.
PC
External transistor
common
(sink) (initial setting)
When connecting the transistor output (open collector output), such
as a programmable controller in sink logic, connect the external
power supply common for transistor output to this terminal to
prevent a malfunction caused by undesirable currents.
Power supply voltage
range 19.2 to 28.8VDC
Permissible load current
100mA
Contact input
common (source)
Common terminal for contact input terminal (source logic)
24VDC power supply Can be used as 24VDC 0.1A power supply.
