Chapter 4 - Parameter Description [I/O]
72
[LV]
MO-MG is CLOSED when the DC link voltage is
below the Low-voltage level.
[MO-MG configured as ‘LV’]
[OH]
MO-MG is CLOSED when the heat sink of the
inverter is above the reference level.
[Lost Command]
MO-MG is CLOSED when frequency reference is
lost.
[Run]
MO-MG is CLOED when the inverter is running.
[Stop]
MO-MG is CLOED when the inverter is stopped.
[Steady]
MO-MG is CLOED when the inverter is steady
speed status.
[Ssearch]
MO-MG is CLOSED during the inverter is speed
searching.
[Ready]
MO-MG is CLOSED when the inverter is ready to
run.
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
normally open contact and 30B-30C is a normally
closed contact.
Bit Setting Display 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.
