5.8.8 Output current detection function
The output current during inverter running can be detected and output to the output terminal.
Output current detection (Y12 signal, Pr.150, Pr.151, Pr.166, Pr.167)
• The output current detection function can be used for purposes such as overtorque detection.
• If the inverter 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.
• 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.
