8.9 “3-phase BLAC/DC (trapezoidal)" advanced settings
Clicking the "advanced settings" button (see Figure 13 ) opens the "advanced settings"
dialog box (see Figure 14 ). This is where the advanced "3-phase BLAC/DC (trapezoidal)"
motor type parameters are set.
Current reference
The value of current flowing inside one (of three) phases of the motor at run
time in “open loop” “current mode”
Target speed
The target mechanical (rotor) Speed in RPMs (or Hz) if speed regulation is
set to “closed loop” (alternate between RPM and Hz settings by clicking on
the “RPM” button)
Delay coefficient from
RV2-RV3
If the check box (Delay coefficient from RV2-RV3) is checked, then the
Rising/Falling delay are set by R62 and R63. Otherwise if the check box is
unchecked, these two parameters (Rising/Falling delay) can be set by the
user in the following control boxes (B-emf rising/falling edge), in this case
the two parameters are fixed and cannot be modified during the run time.
B-emf rising edge The B-EMF Rising delay coefficient value (from 0 to 255)
B-emf falling edge The B-EMF Falling delay coefficient value (from 0 to 255)
Closed loop parameter (only in closed loop)
Integral coefficient (Ki)
The value of the Integral Coefficient (Ki) of the proportional integrative (PI)
regulator
Proportional coefficient
(KP)
The value of the proportional coefficient (Kp) of the PI regulator
Sampling time The 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 8.9: “3-phase BLAC/DC (trapezoidal)" advanced
settings on page 24 )
Generate source files
the “generate source files” button enables the user to generate the
configuration “.h” files shown in
Table 7 - configuration ".h" files. A “save”
dialog window appears, where the user can select in which folder to create
the file. User must choose the right “Source” directory in the firmware
working folder (see
Section 8.5: Firmware description on page 21 ).
