ABOV FOC Solution ③ -  aFDT(ABOV FOC Development Tool)

ABOV provides FOC Total Solution consisting of H/W and S/W Solution.

Part 3 is about AFDT

The ABOV FOC Development Tool (aFDT) is a motor control parameter setting program for using the ABOV 1-Shunt & 3-Shunt FOC Library.

When setting the control parameter for each block using aFDT, the 16-bit array data is generated. This array of data is applied as a control parameter of the FOC Algorithm layer. In addition, aFDT can transmit parameter array data to UART and can perform motor control optimal tuning by a parameter applied in real-time.

[Figure 3] aFDT Parameter Setting Window

In aFDT, the user can directly input various control parameters required for sensor-less FOC control. Types of parameters include Motor Parameter, Inverter Board H/W Parameter, Align, Acceleration, Estimator Bandwidth, Speed Controller PI Control Gain, Current Control Bandwidth, Flux Weakening, Software Overcurrent Level, etc. The users can set the FOC control parameter to the desired value through this function.

In addition, as shown in [Figure 4], aFDT is equipped with a function to monitor fourteen variables inside the FOC Algorithm Layer using UART communication. This makes it easier to perform motor control tuning.

ABOV’s MCU supporting aFDT is shown in <Table 1> below.

When developing the motor applications using the ABOV 1-Shunt & 3-Shunt FOC Libraries and aFDT, the development GUI tool, the users can receive extensive development support from H/W design to S/W. In addition, Motor Control Tuning, which is the biggest concern for Motor Control Engineers, can be performed more easily and conveniently than before.
