RES
Reset
Use this signal to reset a fault output provided when a protective
function is activated.
Turn ON the RES signal for 0.1 seconds or longer, then turn it OFF.
Input resistance: 4.7 k

,
voltage when contacts are
open: 21 to 27 VDC,
current when contacts are
short-circuited: 4 to 6 mADC
SOF
Converter stop
Turn ON this signal to stop the regenerative driving. The function
can be changed using
Pr.4

LOH
Box-type reactor
overheat protection
Used to monitor the speed of cooling fan in the FR-XCB reactor for
overheat protection.
When the sink logic is selected, connect this terminal to terminal LOH1
on the reactor.
When the source logic is selected, connect this terminal to terminal
LOH2 on the reactor.
SD
Contact input
common
(sink) (initial setting)
Common terminal for the contact input terminal (sink logic).
̶
External transistor
common (source)
Connect this terminal to the power supply common terminal of a
transistor output (open collector output) device, such as a
programmable controller, in the source logic to avoid malfunction by
undesirable current.
24 VDC power
supply common
Common output terminal for 24 VDC 0.1A power supply (PC
terminal).
Isolated from terminals 5, SE, and SE2.
PC
External transistor
common
(sink) (initial setting)
Connect this terminal to the power supply common terminal of a
transistor output (open collector output) device, such as a
programmable controller, in the sink logic to avoid malfunction by
undesirable current.
Power supply voltage range:
19.2 to 28.8 VDC,
permissible load current: 100
mA
Contact input
common (source)
Common terminal for contact input terminal (source logic)
24 VDC power
supply
Can be used as a 24 VDC 0.1 A power supply.

RYA
Inverter run enable
(NO contact)
Turns ON when the multifunction regeneration converter becomes
ready for operation.
Signal OFF: Inverter cannot run
Signal ON: Inverter can run
Permissible load: 24 VDC
(27 VDC at maximum) 0.1 A
(The voltage drop is 2.8 V at
maximum while the signal is
ON.)
RYB
Inverter run enable
(NC contact)
Turns ON at alarm occurrence and reset (RES) signal input.
Connect this terminal to the inverter terminal which the X10 signal is
assigned to or the inverter terminal MRS.
Terminal RYB is used with the normally closed (NC contact)
specification.
Turning ON the RYB signal stops the inverter.
Signal OFF: Inverter can run
Signal ON: Inverter cannot run
RSO
Converter reset
Turns ON during a converter reset (RES-ON).
Connect this terminal to the inverter terminal which the RES signal is
assigned to.
Turning ON the RSO signal resets the inverter.
SE
Open collector
output common
Common terminal for terminals RYA, RYB, and RSO.
Connect it to the inverter terminal SD (sink logic).

A, B, C
Fault contact
1 changeover contact output that indicates that an converter's
protective function has been activated and the outputs are stopped.
Fault: discontinuity across B and C (continuity across A and C),
Normal: continuity across B and C (discontinuity across A and C)
Contact capacity: 230 VAC 0.3
A
(power factor = 0.4),
Output: 30 VDC 0.3 A
