Over torque (OTQ)
This function can detect that estimated value of output torque
of motor increase more than optional level and outputs.
When over torque signal is selected in intelligent output
selection, this function is valid.
This function is valid just when sensorless vector control, 0Hz
domain sensorless vector control, or vector control with sensor
is selected. Make sure that output is unstable except these
controls.
Alarm code output (AC0-AC3)
This is the function that inverter outputs trip factor as signal.
When 01(3bit) or 02(4bit) is selected in alarm code selection,
intelligent output terminal, 11-13 or 11-14 compulsorily is outputted in alarm code.
Alarm code output is the following below.
