6.10.7 Output current detection function (Y12, Y13, Pr. 150 to Pr. 153)
The output power during inverter running can be detected and output to the output terminal.
The above parameters can be set when Pr. 160 "User group read selection" = 0.
Output current detection (Y12, Pr. 150, Pr. 151, Pr. 166, Pr. 167)
The output current detection function can be used for excessive torque detection, etc.
If the output current remains higher than the Pr. 150 setting during inverter operation for longer than
the time set in Pr. 151, the output current detection signal (Y12) is output from the inverter's open col-
lector or relay output terminal. When the Y12 signal turns on, the ON state is held for approximately
100 ms.
For the Y12 signal, set "12 (positive logic) or 112 (negative logic)" in Pr. 190 to Pr. 192 "Output terminal
function selection" and assign functions to the output terminal.

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.

Zero current detection level 5% 0–200%
Set the zero current detection level.
The rated inverter current is assumed to be 100%.
153
Zero current detection time 0.5 s 0–1 s
Set this parameter to define the period from when
the output current drops below the Pr. 152 value
until the zero current detection signal (Y13) is
output.
