3. To stop the Inverter and generate a fault at overtorque detection, set n096
to 2 or 4. At detection, the Digital Operator will display an fault
(ON).
Overtorque Detection Level (n098)
Set the overtorque detection current level in units of 1%. (Inverter rated
current = 100%) When detection by torque is selected, the motor rated
torque becomes 100%.
Factory setting: 160%
Overtorque Detection Time (n099)
If the time that the motor current exceeds the Overtorque Detection
Level (n098) is longer than Overtorque Detection Time (n099), the
overtorque detection function will operate.
Factory setting: 0.1 s
Overtorque/Undertorque Detection Function Selection 2
(n097)
When vector control mode is selected, overtorque/undertorque detec-
tion can be performed either by detecting the output current or the out-
put torque.
When V/f control mode is selected, the setting of n097 is invalid, and
overtorque/undertorque is detected by the output current.
 Frequency Detection Level (n095)
Effective when one or more of the Multi-function Output Selections
n057, n058 and n059 are set for frequency detection (setting: 4 or 5).
Frequency detection turns ON when the output frequency is higher or
lower than the setting for the Frequency Detection Level (n095).
Setting Description
0 Detected by output torque
1 Detected by output current
