button and, in case the motor fails to start, adjust start-up settings
and/or advanced settings. When the motor starts, adjust the delay
coefficients for a given duty cycle (speed) to get the best motor
efficiency.
After the Open Loop mode start-up parameters and advanced settings
have been fine tuned, the motor can then be run in Closed Loop mode
based on these parameters.
In Closed Loop mode, start-up parameters must be set again to comply
with the closed loop operation.
It is then possible to run the motor in standalone mode by collecting
real-time data and generating the appropriate header files to be used
with the provided Motor Control library, in order to generate a firmware
to be programmed into the microcontroller. This is explained in detail in
the “Preparing for Standalone Mode: BLDC Motors” section on page 42.
We suggest you to order the SELNI motor and experiment with the AK-
ST7FMC Control Panel’s default settings for this motor, to understand
the interdependence of the various parameters.
Then, run your own motor in Open Loop mode with a speed sensor (this
will allow to monitor the speed and ensure that the stator frequency
doesn't go below the rotor frequency—otherwise reactive current will be
generated by the motor, causing overvoltage on bulk capacitors and
possibly destruction of the board) in order to characterize the motor
and/or to verify that the motor is suitable for the intended load.
After the V/F curve, the start-up parameters and the advanced settings
have been fine tuned, the motor can then be run in Closed Loop mode.
In Closed Loop mode, start-up parameters must be set again to comply
with the closed loop operation.
It is then possible to run the motor in standalone mode by collecting
real-time data and generating the appropriate header files to be used
with the provided Motor Control library, in order to generate a firmware
to be programmed into the microcontroller. This is explained in detail in
the “Preparing for Standalone Mode: AC Motors” section on page 46.
