Fine adjustment meets the need in the age of Flexible Manufacturing System (FMS).
Use PID function to simplify
process control.
The method of operation remains unchanged!
•The two models share external dimensions, basic
functions, and basic operation so you can focus
your selection based on load characteristics.
•The HF Series eliminate complicated setup for
achieving starting torque.

●The sensorless vector control method provides 200% starting torque ! Furthermore, the
maximum torque during operation exceeds 150%.
●The auto tuning function permits high-performance operation.
●This inverter is suitable for machines that need high torque during start-up, slow-speed
operation or regular operation. It is ideal for applications such as extruders, high-viscosity
pumps, cart drivers, elevators, and special agitators, as well as for applications that need
regenerative braking.

Use PID operation to control processes with a feedback
signal. PID control the motor speed to drive the error
between the target value and feedback value to zero.
It is effective for controlling processes such as temperature,
pressure, flow rate, and air capacity.
〈P: Proportional control〉
In this control, the operation quantity is proportional to
the deviation of the target value and feedback value.
P gain setting K
P
•The response of the
operation quantity with
respect to deviation is adjusted.
〈I: Integral control〉
Under the proportional control alone, the operation quantity is
small when the deviation is small; therefore correction may
not be sufficient, and will not coincide with the target value.
I: Integral control is the function to correct the above.
Deviation is accumulated with the passage of time to correct
the operation quantity.

•Integral time is set.
When the integral time
is short (I/K

〈D: Differential operation〉
Differential operation uses the rate of change of the deviation
to adjust the operation quantity. It is used for correction of P
(proportional) and I (integral) control.

AVR function
AVR function selection
AVR motor voltage selection
•Irrespective of the input power, the output voltage is
corrected and maintained at a constant value according
to the motor voltage. (However, output voltage
exceeding the input voltage of the inverter is not
possible.)
•The AVR function can be turned OFF during
deceleration.

Acceleration time crosseover frequency
Deceleration time crossover frequency
•The acceleration and deceleration time can be changed
during operation. Use the 2nd acceleration and 2nd
deceleration times when load inertia changes during
operation.
•Change the acceleration and deceleration time with input
terminals or with the crossover frequency setting.
Acceleration/deceleration pattern
Acceleration pattern selection
Deceleration pattern selection
•The characteristics of acceleration and deceleration can be
selected from among "linear" and "S-curve."
•The S-curve permits softer starts and stops than linear
acceleration/deceleration. It is effective in preventing cargo
from tipping.
