Motor constants calculation disabled.<br />
Description<br />
All constants can be measured in this code but different constants are tuned<br />
according to control mode;<br />
For V/F, Slip compen, Sensorless_S, Sensorless_T:<br />
(No-load current, stator resistance, leakage inductance, stator inductance<br />
available)<br />
Note: Only no-load current can be calculated during V/F and Slip<br />
compensation.<br />
For Vector_SPD, Vector_T:<br />
(No-load current, stator resistance, leakage inductance, stator inductance,<br />
encoder test, rotor filter time constant)<br />
Calculates stator resistance, leakage inductance.<br />
Calculates the encoder status.<br />
Calculates Rotor filter time constant.<br />
6) Sensorless vector control<br />
Set FU2-39 to 2 {Sensorless_S} or 3 {Sensorless_T} to enable Sensorless vector control. It is strongly recommended<br />
to perform Auto-tuning for Sensorless before starting Sensorless control in order to maximize performance. Two types<br />
of Sensorless vector control are available; Sensorless_S or Sensorless_T.<br />
Parameter Name Code Description<br />
Control mode selection FU2-39 Select Sensorless_S or Sensorless_T.<br />
P, I gain for<br />
sensorless control<br />
FU2-45, FU2-46<br />
Set gain for Sensorless_S control.<br />
Starting freq FU1-22 Starting freq of the motor<br />
7) Vector control<br />
Set FU2-39 to 4 {Vector_SPD} or 5 {Vector_TRQ} to enable Vector control. Encoder should be installed to the motor<br />
with Sub-B board in the inverter to start this control.<br />
Parameter Name Code Description<br />
Usage of Pulse<br />
Input Signal<br />
Pulse Input Signal<br />
Selection<br />
EXT -12<br />
EXT -15<br />
Defines the method of pulse input with SUB-B board<br />
mounted. Vector control setting is valid only after this<br />
parameter is set to 1 {Feed-back}.<br />
3 types of pulse input: (A+B), A, -(A+B)<br />
Encoder Pulse Number EXT -16 Enters the pulse number of encoder in the motor.<br />
Before selecting Vector control mode, encoder setting should be done as indicated above. If the parameter value of<br />
actual motor is set in common setting, execute Auto-tuning before selecting vector control mode.<br />
