Overtorque Detection Level (n098)
Set the overtorque detection current level in units of 1%. (Inverter rated
current = 100%) When detection by the output 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).
Frequency Detection 1
Output frequency ≥ Frequency Detection Level n095
(Set n057, n058 or n059 to 4.)
