Parameter
Output current detection (Y12, Pr. 150, Pr. 151, Pr. 166, Pr. 167)
The output power 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 set in Pr. 166 . When Pr. 166 =
9999, the ON state is held until a next start.
At the Pr. 167 setting of "1" or "11", the inverter output is stopped and the output current detection
alarm (E.CDO) is displayed when the Y12 signal turns on. When an alarm stop 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". Setting Pr. 167 = "1" or "11" at Y12 signal
ON does not cause E.CDO. Setting to Pr. 167 becomes effective after Y12 is turned OFF.
Set "12 (source logic)" or "112 (sink logic)" to any of Pr.190 to Pr. 196 "Output terminal function
selection" to assign the function of the Y12 signal to the output terminal.
