Motor control operations

UM0432

30/53

Start-up stator frequency

Sets the stator frequency during the start-up sequence (only in closed loop).

Max duration

Sets the maximum duration of the start-up sequence in milliseconds (ms) (only in

closed loop).

Min rotor frequency to validate

closed loop

Sets the rotor speed or frequency to validate the closed-loop mode (only in closed

loop).

Regulator settings

Integral coefficient (Ki)

Sets the value of the integral coefficient (Ki) of the proportional integrative (PI)

regulator.

Proportional coefficient (Kp)

Sets the value of the proportional coefficient (Kp) of the PI regulator.

Sampling time

Sets the regulator sampling frequency in milliseconds (ms).

Phase shift

Set phase shift according to

Ph/F Curve

Software sets (in run time) the actual phase shift from the Ph/F curve defined in

the advanced settings (based on the rotor speed).

Set phase shift according by

Manual setting of the phase shift using potentiometer P3; the maximum CCW

position is 0° of phase shift and the maximum CW position is 360° of phase shift.

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 7.4.7).

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).
