Precautions for Correct Use
To conduct encoder feedback, see also 7-2-16 Encoder Feedback Control on page 7-37.
To use a synchronous motor (SM)/permanent magnet
motor (PMM).
Proceed to 7-2-11 Synchronous Motor (Permanent
Magnet Motor) Control on page 7-22.
Use an induction motor (IM).
Proceed to #2
No feedback is to be used. To use in applications that require feedback from
encoders, sensors, etc.
To use in applications: that carry a heavy load;
that require control needing a high torque; and
that require position control.
Proceed to 7-2-10 Vector Control with Sensor
on page 7-19.
To use in applications where a motor with an
encoder is driven and the frequency-voltage
characteristics of the motor need to be changed
freely as intended.
Proceed to 7-2-14 Free V/f Control with Sensor
on page 7-34.
To use in applications: where a motor with an
encoder is driven; that require a certain torque
at the start; and where the motor revolution
speed needs to be equal to the command
speed.
Proceed to 7-2-15 Automatic Torque Boost
Control with Sensor on page 7-36.
To use in applications where afan/pump with an
encoder is driven and where the motor revolu-
tion speed needs to be equal to the command
speed while the energy consumption needs to
be reduced.
Proceed to 7-2-13 V/f Control with Sensor
(Reducing Torque Characteristics) on page
7-33.
To use in applications where a motor with an
encoder is driven and where the motor needs
to be used with generic characteristics of V/f
control.
Proceed to 7-2-12 V/f Control with Sensor
(Constant Torque Characteristics) on page
7-32.
To use in applications, such as lifts and cranes,
that require a high torque from the start.
Proceed to 7-2-9 Zero-speed Range (Zero-Hz
Range) Sensorless Vector Control on page
7-17.
To use in applications, such as conveyors and
machine tools, that carry heavy loads and
require a high torque.
Proceed to 7-2-8 Sensorless Vector Control on
page 7-15.
To use in applications where the fre-
quency-voltage characteristics of a high-speed
motor/special motor need to be changed freely
as intended.
Proceed to 7-2-3 V/f Control (Free V/f) on page
7-7.
To use in applications that require a certain
torque at the start though the load is light.
Proceed to 7-2-5 Manual Torque Boost on page
7-11 or 7-2-6 Automatic Torque Boost on page
7-12.
V/f control is used for saving energy according
to a fan/pump.
Proceed to 7-2-2 V/f Control (Reducing Torque
Characteristics) on page 7-6.
To use with generic characteristics of V/f con-
trol.
Proceed to 7-2-1 V/f Control (Constant Torque
Characteristics) on page 7-5.
