"3-phase BLAC/DC (trapezoidal)" advanced settings

When you click on the Advanced Settings button (see Figure 14) the Advanced Settings

dialog box appears (see Figure 15). This is where the advanced "3-phase BLAC/DC

(trapezoidal)" motor type parameters are set.

Figure 15.

"3-phase BLAC/DC (trapezoidal)" advanced parameters window

B-emf rising edge

B-EMF rising edge delay coefficient value (from 0 to 255).

B-emf falling edge

B-EMF falling edge delay coefficient value (from 0 to 255).

Closed-loop parameter (only in closed loop)

Integral coefficient (Ki)

Value of the integral coefficient (Ki) of the proportional integrative (PI) regulator.

Proportional coefficient

(KP)

Value of the proportional coefficient (Kp) of the PI regulator.

Sampling time

Regulation sampling time (in milliseconds).

Change motor type

The Change Motor Type button enables the user to change the motor type (see

Figure 13).

Advanced settings

The Advanced Settings button enables the user to set the advanced parameters (see

Section 7.4.5).

Generate source files

The Generate Source Files button enables the user to generate the configuration ".h"

files shown in Table 7: ".h" configuration files. A "Save" dialog window appears, where the

user can select the folder in which to create the file. The user must choose the correct

"Source" directory in the firmware working folder (see Section 7.4.1).
