Description
Used to impose DC on the induction motor
for braking control.
Set the DC braking current in percentage g
based on the rated current of the Inverter based on the rated current of the Inverter
as 100%.

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
deceleration.
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 current of the Inverter as 100%.
Used to select a function to reduce the
output frequency of the Inverter
automatically for stall prevention during
operation.
Set the level in percentage based on the
rated current 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 detection 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 continues (issues alarm)
4: Overtorque always detected and output
shut off (for protection)
Used to set overtorque detection level.
Set the level in percentage based on the
rated current of the Inverter as 100%.
Used to set the detection time of
overtorque.
