I/O-45: Fault Output Relay (30A, 30B, 30C)
This function is used to allow the fault output relay to
operate when a fault occurs. The output relay terminal is
30A, 30B, 30C where 30A-30C is a norm ally open
contact and 30B-30C is a normally closed contact.

Description
0
000
Fault output relay does not
operate at ‘Low voltage’ trip.
Bit 0
(LV)
1
001
Fault output relay operates at
‘Low voltage’ trip.
0
000
Fault output relay does not
operate at any fault.
Bit 1
(Trip)
1
010
Fault output relay operates at
any fault except ‘Low voltage’
and ‘BX’ (inverter disable) fault.
0
000
Fault output relay does not
operate regardless of the retry
number.
Bit 2
(Retry)
1
100
Fault output relay operates
when the retry number set in
FU2-26 decreases to 0 by
faults.
☞
When several faults occurred at the same time, Bit 0 has
the first priority.
I/O-46: Inverter Number
I/O-47: Baud Rate
This code sets the inverter number. This number is used
in communication between inverter and communication
board.
This code sets the communication speed. This is used in
communication between inverter and communication
board.
I/O-48: Operating at Loss of Freq. Reference
I/O-49: Waiting Time after Loss of Freq.
Reference
There are two kinds of loss of frequency reference. One
is the loss of digital frequency reference and the other is
of analog frequency reference.
Loss of digital frequency reference is applied when DRV-
04 [Frequency Mode] is set to ‘Keypad-1’ or ‘Kepad-2’.
At this time, the ‘Loss’ means the communication error
between inverter and keypad or communication board
during the time set in I/O-49.
Loss of analog frequency reference is applied when
DRV-04 [Frequency Mode] is set to other than ‘Keypad-
1’ or ‘Kepad-2’. At this time, the ‘Loss’ is determined by
the criteria set in I/O-11 [Criteria for Analog Input Signal
Loss].

0
Inverter keeps on operating at the
previous frequency.
FreeRun
(Coast to stop)
1
Inverter cuts off its output.
Stop
2
Inverter stops with Decel time (DRV-
02) and Decel pattern (FU1-26).
This is the time inverter determines whether there is a
frequency reference or not. If there is no frequency
reference satisfying I/O-11 during this time, inverter
determines that it has lost of frequency reference.
