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 c rrent of the In erter
as 100%.

Used to select a function to change the de-
celeration time of the motor automatically
so that there will be no overvoltage im-
posed on the motor during deceleration.
0: Stall prevention during deceleration en-
abled
1: Stall prevention during deceleration dis-
abled
Used to select a function to stop the accel-
eration 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 out-
put 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 meth-
od after overtorque detection.
0: Overtorque detection disabled
1: Overtorque detection only when speed
coincides and operation continues (is-
sues alarm)
2: Overtorque detection only when speed
coincides and output shut off (for protec-
tion)
3: Overtorque always detected and opera-
tion 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 overtor-
que.
