Torque detection
If an excessive load is applied to the machine, the resultant output current increase can
be compared to the threshold setting of parameter n098, then output alarm signals to
multi-function output terminals MA, MB, P1 and P2.
To output an overtorque detection signal, set output terminal function selection n057 to
n059 to "overtorque detection" [Setting:6 (NO contact) or 7 (NC contact)].
∗
Overtorque detection release width (hysterisis) is set at approx. 5% of inverter rated current.
