The over torque detection function monitors the inverter output current or motor torque and can be used to detect
an increase in inverter current or motor torque (e.g. heavy load).
The torque detection level (08-15) is based on the inverter rated output current (100% = inverter rated output
current) when operating the inverter in V/F control and motor output torque (100% = motor rated torque) when
operating the inverter in SLV control.
Over-torque detection
Parameter 08-13 selects over-torque detection function. An over-torque condition is detected when the output
current / torque rises above the level set in parameter 08-15 (Over-torque detection level) for the time specified in
parameter 08-16 (Over-torque detection time).
08-13=0:
Over-torque detection is disabled.
08-13=1:
Over-torque detection is enabled when the output frequency reaches the set frequency.
08-13=2:
Over-torque detection is enabled during running.
Parameter 08-14 selects the way the inverter acts when an over-torque condition is detected.
08-14=0:
When an over-torque condition is detected the inverter displays an over-torque detection fault and the
motor decelerates to a stop.
08-14=1:
When an over-torque condition is detected the inverter displays an over-torque detection alarm and
continues to run.
08-14=2:
When an over-torque condition is detected the inverter displays an over-torque detection fault and the
motor coasts to a stop
