Output current detection
(Y12 signal, 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 collector or relay output terminal.
When the Y12 signal turns ON, the ON state is held for the
Time
time set in Pr. 166.
When Pr. 166 = "9999", the ON state is held until a next start.
OFF
At the Pr. 167 setting of "1", the inverter trips, and the output
current detection fault (E.CDO) is displayed when the Y12
signal turns ON. When fault occurs, the Y12 signal is ON for
the time set in Pr. 166 at the Pr. 166 setting of other than
9999, and remains ON until a reset is made at the Pr. 166
setting of 9999. E.CDO does not occur even if "1" is set in Pr.
167 while Y12 is ON. The Pr. 167 setting is valid after Y12
turns OFF.
For the Y12 signal, set "12 (positive logic) or 112 (negative
logic)" in Pr. 190 or Pr. 192 (output terminal function selection)
and assign functions to the output terminal.
