Set the output current detection level.
0 to 220%
100% is the rated inverter current.
Set the output current detection time. Set the time
from when the output current reaches the setting or
0 to 10 s
higher until the output current detection (Y12) signal
is output.
Set the zero current detection level.
0 to 220%
The rated inverter current is regarded as 100%.
Set the time from when the output current drops to
0 to 10 s the Pr.152 setting or lower until the zero current
detection (Y13) signal is output.
0 to 10 s Set the retention time when the Y12 signal is ON.
Retain the Y12 signal ON status. The signal is turned
9999
OFF at the next start.
Select the operation when Y12 and Y13 signals turn
0, 1, 10, 11
ON.
• The output current detection function can be used for purposes such
as overtorque detection.
• If the output during inverter running remains higher than the Pr.150
setting for the time set in Pr.151 or longer, the Output current detection
(Y12) signal is output from the inverter's open collector or relay output
terminal.
• When the Y12 signal turns ON, the ON state is retained for the time set
in Pr.166.
• When Pr.166 = "9999", the ON state is retained until the next start.
• Setting Pr.167 = "1" while the Y12 signal is ON does not cause E.CDO.
The Pr.167 setting becomes valid after the Y12 signal is turned OFF.
• For the Y12 signal, set "12 (positive logic) or 112 (negative logic)" in
any of Pr.190 to Pr.196 (output terminal function selection) to
assign the function to the output terminal.
• Select whether the inverter output stops or the inverter operation
continues when Y12 signal turns ON, by setting Pr.167.
