P6 Overtorque/ Undertorque Detection
When the load is too heavy (overload) or suddenly drops ( undertorque), the drive will output a
torque detection signal to the multi-function output terminal ( Relay 1, Relay 2, D1-DC or
D2-DC). The torque detection function is set by P6 parameters.
CAUTION! When overtorque occurs, the drive may trigger the fault to stop the motor. To prevent the drive from
stopping, use torque detection to indicate an overload situation before the fault is triggered. Simimar situations
also apply to undertorque. Use undertorque detection to find out application problems such as torn belte, a pump
shutting off and etc.
