C
Over current
alarm
1-2000A
(500A)
When the current is higher than the
value and comes into over current
delay but still higher (over current
delay), then over current alarms. If the
value is set as 2000, then the alarm is
disabled.
D
Over phase
current delay
0-3600.0s
(1296s)
When this parameter is set to 0, the
over current delay is the inverse time;
if not, the over current delay is the time
set for this parameter.
E
485 baud rate 0-4800
1-9600
2-19200
