Stall Prevention Level during Acceleration (n56)
Set the operation level of a function to stop the acceleration of
the motor automatically for stall prevention during acceleration.
Set this value in percentage based on the rated output current of
the Inverter as 100%.

Stall Prevention Level during Operation (n57)
Select the operation level of a function to reduce the output fre-
quency of the Inverter automatically for stall prevention during
operation. Set this value in percentage based on the rated output
current of the Inverter as 100%.

Frequency Detection Level (n58)
Set the frequency to be detected.
Note: When frequency detection 1 and 2 are to be output, n40

Overtorque Detection Function Selection
(n59 to n61)
Set n59 to enable or disable overtorque detection and select the
processing to be performed after overtorque detection.
Value
0 Inverter does not monitor overtorque.
1 Inverter monitors overtorque only when speed is matched.
It continues operation (issues warning) even after overtorque is
detected.
2 Inverter monitors overtorque only when speed is matched.
It discontinues operation (through protective function) when
overtorque is detected.
3 Inverter always monitors overtorque during operation.
It continues operation (issues warning) even after overtorque is
detected.
4 Inverter always monitors overtorque during operation.
It discontinues operation (through protective function) when
overtorque is detected.
Set the overtorque detection level in n60 and the overtorque
detection time in n61.

Note: 1. In n60, set the overtorque detection level in percentage
