6-23
3) DIO_46 (Fault output relay (30A, 30B, 30C))
This function can be used when the inverter fault signal is generated through the relay contact. the fault alarm is
triggered differently by setting the bits related to the low voltage trip, inverter trip and the number of retry.

Bit Setting Description
0 Deactivated at Low Voltage Trip
Bit 0
(LV)
1 Activated at Low Voltage Trip
0 Deactivated at any fault
Bit 1
(Trip)
1 Activated at any fault except Low Voltage Trip
0 Deactivated at the auto retry attempt
Bit 2
(Retry)
1 Activated at the number of auto retry attempt
4) DIO_59 ~ 61 (Overload trip enable, level, time)
If the inverter output current higher than the overload limit level is kept for the overload limit time, the inverter
blocks the gating of IGBTs and issues the trip message.
Code Display Description Range Unit Default
DIO_59 OLT select Overload trip enable Yes/No - Yes
DIO_60 OLT level Overload trip level 30 ~ 250 % 180
DIO_61 OLT time Overload trip time 0 ~ 60 sec 60
z Note: DIO_60 is set as the percentage of Motor rated current.
5) DIO_97(Operation method when losing command)
You can choose the operation method when multi-function analog input signal satisfying the criteria for
the signal loss of analog input and the condition of multi-function analog input signal loss judging time.
Refer to analog I/O Group for the criteria for the multi-function analog input signal loss and the judging time
of signal loss.
