 Control Mode Selection (A1-02)

There are three control modes available. Select the control mode that best suits the application the drive will control.

 Normal / Heavy Duty Selection (C6-01)

The drive supports two ratings, Normal Duty and Heavy Duty. Both have different output current ratings (refer to the

catalog or the Technical Manual). Set the Duty mode in accordance with the application.

 Auto-Tuning (T1-)

Auto-Tuning automatically sets up the motor data relevant drive parameters. Three different modes are supported.

Control Mode

<1> For explanations of these control modes, refer to the Technical Manual.

Parameter Main Applications

V/f Control for Induction

Motors

A1-02 = 0

(default)

• General variable speed applications, particularly useful for running multiple motors from a

single drive.

• When replacing a drive in which parameter settings are unknown.

V/f Control with PG Speed

Feedback

A1-02 = 1

• For general-purpose applications that do not require high dynamic response but high speed

accuracy.

• This mode should be used if the motor parameters are unknown and Auto-Tuning cannot be

performed.

Open Loop Vector Control A1-02 = 2

• General variable speed applications

• Applications requiring high precision, high speed control

Closed Loop Vector

Control <1>

A1-02 = 3

• For general, variable-speed applications that requiring precise speed control down to zero

speed, fast torque response, or precise torque control.

• A speed feedback signal from the motor is required.

Open Loop Vector Control

for PM <1>

A1-02 = 5

Derated torque-load applications employing permanent magnet motors (SPM, IPM) and energy

savings.

Advanced Open Loop

Vector C o ntrol for P M <1>

A1-02 = 6 This control mode can be used to operate an IPM motor for constant torque applications.

Closed Loop Vector

Control for PM <1>

A1-02 = 7

• This mode can be used for high precision control of a PM motor in constant torque or variable

torque applications.

• A speed feedback signal is required.

Mode Heavy Duty Rating (HD) Normal Duty Rating (ND)

C6-01 01

Application

Applications with a constant torque like extruders,

conveyors and cranes. High overload capability

might be needed.

Applications where the torque increases with the speed

like fans or pumps. High overload tolerance is normally

not needed.

Rotational Auto-

Tuning

T1-01 = 0

• Motor can be decoupled from the load and rotate freely

while Auto-Tuning is performed.

• Motor and load can not be decoupled but the motor load

is below 30%.

• Rotational Auto-Tuning gives the most accurate results,

and is therefore highly recommended if possible.
