When excess load is placed on machine, the increase in motor current is detected. If current exceeding the
value set by Pn-38 lasts for a time exceeding the value set by Pn-39, the overtorque detected signal is
output to control circuit terminal 13 or 14 until the current reduced to the Pn-38 set value or less. To output
the signal to control circuit terminal 13 , set Pn-34 to 4, and to 14, Pn-35 to 4.
The Pn-37 setting can select overtorque detection only during agreed speed or during running
Additionally, it can select continuous operation or output shut-off at overtorque detection.
Pn-37 = X 0 0 X
2nd digit
0:Overtorque is detected only during agreed frequency.
1:Overtorque is detected during running except for DB.
3rd digit
0: When overtorque is detected, the operation continues.
1: When overtorque is detected, the inverter output is shut OFF.
Fault contact signal is output. (Treated as a fault)
