Description

All constants can be measured in this code but different constants are tuned

according to control mode;

For V/F, Slip compen, Sensorless_S, Sensorless_T:

(No-load current, stator resistance, leakage inductance, stator inductance

available)

Note: Only no-load current can be calculated during V/F and Slip

compensation.

For Vector_SPD, Vector_T:

(No-load current, stator resistance, leakage inductance, stator inductance,

encoder test, rotor filter time constant)

Calculates stator resistance, leakage inductance.

Calculates the encoder status.

Calculates Rotor filter time constant.

6) Sensorless vector control

Set FU2-39 to 2 {Sensorless_S} or 3 {Sensorless_T} to enable Sensorless vector control. It is strongly recommended

to perform Auto-tuning for Sensorless before starting Sensorless control in order to maximize performance. Two types

of Sensorless vector control are available; Sensorless_S or Sensorless_T.

Parameter Name Code Description

Control mode selection FU2-39 Select Sensorless_S or Sensorless_T.

P, I gain for

sensorless control

FU2-45, FU2-46

Set gain for Sensorless_S control.

Starting freq FU1-22 Starting freq of the motor

7) Vector control

Set FU2-39 to 4 {Vector_SPD} or 5 {Vector_TRQ} to enable Vector control. Encoder should be installed to the motor

with Sub-B board in the inverter to start this control.

Parameter Name Code Description

Input Signal

Pulse Input Signal

Selection

EXT -12

EXT -15

Defines the method of pulse input with SUB-B board

mounted. Vector control setting is valid only after this

parameter is set to 1 {Feed-back}.

3 types of pulse input: (A+B), A, -(A+B)

Encoder Pulse Number EXT -16 Enters the pulse number of encoder in the motor.

Before selecting Vector control mode, encoder setting should be done as indicated above. If the parameter value of

actual motor is set in common setting, execute Auto-tuning before selecting vector control mode.
