77
bC-06
Input terminals status of latest fault
Default
0
Description
It displays the status of all DI terminals when the latest fault occurs. The
sequence is as follows:
BIT9 BIT8 BIT7 BIT6 BIT5 BIT4 BIT3 BIT2 BIT1 BIT0
DI0 DI9 DI8 DI7 HDI DI5 DI4 DI3 DI2 DI1
If a DI is ON, the setting is 1. If the DI is OFF, the setting is 0. The value is
the equivalent decimal number converted from the DI status.
bC-07
Output terminal status of latest fault
Default
0
Description
It displays the status of all output terminals when the latest fault occurs. The
sequence is as follows:
BIT4 BIT3 BIT2 BIT1 BIT0
DO2 DO1 REL2 REL1 FMP
If an output terminal is ON, the setting is 1. If the output terminal is OFF,
the setting is 0. The value is the equivalent decimal number converted from
the DI statuses.

5.13 Group bd Motor protection
bd-00
Overset alarm current value
Default
0.00
Setting Range
0.0~600A
bd-01
Overcurrent alarm delay time
Default
0.00
Setting Range
0.0~600s
For example: 4KW inverter rated current is 9A, customer site needs to protect motor when load current is at 6A
more than 5s, corresponding setting parameters: bd-00=6.00A and bd-01=5.0S exceeds current and time panel
display Err24 protection error and stop.
