Learning Basic Features
Basic Tasks Description Ref.
Linear V/F pattern operation
Configures the inverter to run a motor at a constant
torque. To maintain the required torque, the operating
frequency may vary during operation.
p.125
Square reduction V/F pattern
operation
Configures the inverter to run the motor at a square
reduction V/F pattern. Fans and pumps are appropriate
loads for square reduction V/F operation.
p.126
User V/F pattern
configuration
Enables the user to configure a V/F pattern to match the
characteristics of a motor. This configuration is for special-
purpose motor applications to achieve optimal
performance.
p.127
Manual torque boost
Manual configuration of the inverter to produce a
momentary torque boost. This configuration is for loads
that require a large amount of starting torque, such as
elevators or lifts.
p.129
Automatic torque boost
Automatic configuration of the inverter that
provides ”auto tuning” that produces a momentary torque
boost. This configuration is for loads that require a large
amount of starting torque, such as elevators or lifts.
p.130
Output voltage adjustment
Adjusts the output voltage to the motor when the power
supply to the inverter differs from the motor’s rated input
voltage.
p.131
Accelerating start
Accelerating start is the general way to start motor
operation. The typical application configures the motor to
accelerate to a target frequency in response to a run
command, however there may be other start or
acceleration conditions defined.
p.132
Start after DC braking
Configures the inverter to perform DC braking before the
motor starts rotating again. This configuration is used
when the motor will be rotating before the voltage is
supplied from the inverter.
p.132
Deceleration stop
Deceleration stop is the typical method used to stop a
motor. The motor decelerates to 0 Hz and stops on a stop
command, however there may be other stop or
deceleration conditions defined.
p.133
Stopping by DC braking
Configures the inverter to apply DC braking during motor
deceleration. The frequency at which DC braking occurs
must be defined and during deceleration, when the motor
