Description
Used to impose DC on the induction motor for
braking control.
Sets the DC braking current as a percentage Sets the DC braking current as a percentage
based on the rated current of the Inverter as

Used to select a function to change the decel-
eration 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
* Be sure to set the parameter to 1 when the
Braking Resistor Unit or a braking resistor is
used as an option.
Used to select a function to stop the accelera-
tion of the motor automatically for stall preven-
tion during acceleration.
Sets the level as a 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.
Sets the level as a percentage based on the
rated current of the Inverter as 100%.
Used to set the frequency to be detected.
* The parameter n059 for multi-function out-
put 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 over-
torque detection.
0: Overtorque detection disabled
1: Overtorque detection only when speed coin-
cides and operation continues (issues
alarm)
2: Overtorque detection only when speed coin-
cides and output turned OFF (for protection)
3: Overtorque always detected and operation
continues (issues alarm)
4: Overtorque always detected and output
turned OFF (for protection)
Select the item to detect overtorque.
0: Detected from output torque.
1: Detected from output current.
