— 146 Parameter for manufacturer setting. Do not set.
Detection of output current (Y12 signal)
and Detection of zero
current (Y13 signal)
150
Output current detec-
tion level
0.1% 150% 0–200%
Set the output current detection
level. 100% is the rated inverter
current.
✔ ✔ ✔
6-105
151
Output current detec-
tion signal delay time
0.1s 0s 0–10s
Set the output current detection
period. Set the time from when the
output current has risen above the
setting until the output current
detection signal (Y12) is output.
✔ ✔ ✔
152
Zero current detection
level
0.1% 5% 0–200%
Set the zero current detection
level. Suppose that the rated
inverter current at the specified
overload capacity is 100%.
✔ ✔ ✔
153
Zero current detection
time
0.01s 0.5s 0–1s
Set this parameter to define the
period from when the output cur-
rent drops below the Pr. 152 value
until the zero current detection
signal (Y13) is output.
✔ ✔ ✔
166
Output current detec-
tion signal retention
time
0.1s 0.1s
0–10 s
Set the retention time when the
Y12 signal is ON.
✔ ✔ ✔
9999
The Y12 signal ON status is retai-
ned. The signal is turned off at the
next start.
167
Output current detec-
tion operation selection
1 0
0
Operation continues when the Y12
signal is ON
✔ ✔ ✔
1
The inverter is brought to trip
when the Y12 signal is ON.
