I/O-45: Fault Output Relay (30A, 30B, 30C)
I/O? Relay mode
45 010
Factory Default:
010
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
Fault output relay does not
operate at ' Low voltage' trip.
Fault output relay operates at
' Low voltage' trip.
Fault output relay does not
operate at any fault.
Fault output relay operates at
any fault except ' Low voltage'
and ' BX' (inverter disable) fault.
Fault output relay does not
operate regardless of the retry
number.
Fault output relay operates
when the retry number set in
FU2-26 decreases to 0 by
faults.

Chapter 6 - Parameter Description [I/O]
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
I/O?Lost command
48 None
Factory Default:
None
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].

I/O? Time out
49 1.0 sec
Factory Default:
1.0 sec
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.
