The over torque detection function monitor the inverter output current or motor torque and can be used to detect
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.
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 and 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 (OL3)
and continues to run.

Use of this mode for any application must be considered carefully and all safety implications must be
taken into account. When enabled and Fire Mode is activated (See multi-function digital inputs,

If the inverter leakage current is greater than 50% of inverter rated current and the ground fault function is
enabled (08-18=1), the keypad will display a "GF", motor will coast to a stop and fault contact is activated.
Note:
this function is only available for inverter Frames 3, 4.
