The above parameters can be set when Pr. 160 = 0.
When Pr. 570 "Multiple rating setting" = 1, performing parameter clear changes the initial
value and setting range. (Refer to section 6.2.5.)

Initial Setting
Description
Value Range
Set the output current detection level.
0–120%
110%
100% is the rated inverter current.
Set the output current detection period.
Set the time from when the output current
0s 0–10s
has risen above the setting until the output
current detection signal (Y12) is output.
Set the zero current detection level.
5% 0–150% The rated inverter current is assumed to be
100%.
Set this parameter to define the period
from when the output current drops below
0.5s 0–10s
the Pr. 152 value until the zero current
detection signal (Y13) is output.
Set the retention time when the Y12 signal
0–10s
is on.
0.1s
The Y12 signal on status is retained. The
9999
signal is turned off at the next start.
