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.

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 or Sub-D boards in the inverter to start this control.

Motor constants calculation disabled
All constants can be measured in this code but different constants are tuned
according to control mode type;
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
Calculate stator resistance, leakage inductance
Calculate the encoder status
Calculate Rotor filter time constant

Code
Defines the method of pulse input with SUB-B or SUB-D
EXT-12 boards 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)
EXT-15
EXT-16 Enter the pulse number of encoder in the motor.
