Used to select a function to change the deceleration
time of the motor automatically so that there will be
no overvoltage imposed on the motor during decel-
eration.
0: Stall prevention during deceleration enabled
1: Stall prevention during deceleration disabled
Used to select a function to stop the acceleration of
the motor automatically for stall prevention during
acceleration.
Set the level in percentage based on the rated cur-
rent of the Inverter as 100%.
Used to select a function to reduce the output fre-
quency of the Inverter automatically for stall preven-
tion during operation.
Set the level in percentage based on the rated cur-
rent of the Inverter as 100%.
Used to set the frequency to be detected.
Note The parameter n40 for multi-function output
must be set for the output of frequency detec-
tion levels 1 and 2.
Used to enable or disable overtorque detection and
select the processing method after overtorque
detection.
0: Overtorque detection disabled
1: Overtorque detection only when speed coincides
and operation continues (issues alarm)
2: Overtorque detection only when speed coincides
and output shut off (for protection)
3: Overtorque always detected and operation con-
tinues (issues alarm)
4: Overtorque always detected and output shut off
(for protection)
