6.5 An example
In this example it is assumed that the QMot Motor QBL4208-41-04-006 is connected to the motor
output connector. The evaluation board is connected to an RS232 interface of the PC by using a null
modem cable. The board is supplied with 24V (DC).
At first, we would like to use the sensorless block commutation with hallFX
output connector. The evaluation board is connected to an RS232 interface of the PC by using a null
modem cable. The board is supplied with 24V (DC).
At first, we would like to use the sensorless block commutation with hallFX
™ to run the BLDC motor.
Please check if the jumpers X212, X213 and X214 are plugged. Then start the PC software and
establish a connection between the evaluation board and the PC.
Thereafter set the operating mode to “Block, HallFX, Closed Loop” to ramp up with block
commutation and closed loop current control. Then enter the parameters as shown in Figure 14.
Please keep in mind to press the “Set” buttons. Thereafter, press the “Start” button and the motor will
ramp up via closed loop current control and will run by using the sensorless BLDC back EMF
commutation hallFX™.

After startup, the motor accelerate up to the defined speed reference value (Speed Ref.). In this
example the speed reference value is set to 3000rpm. The PWM duty cycle is about 62 % dependent
on the mechanical load.
Now, we would like to disable the speed control. Please deactivate the option “Enable speed control”
and set the duty cycle referenc
e value (Duty Cycle Ref.) to 62 %. Then press the “Set” button. The
motor will run without speed control. The PWM duty cycle is fixed. You can change the PWM duty
cycle by setting a new duty cycle reference value (Duty Cycle Ref.).
If you would like to start the BLDC motor with sinusoidal commutation, an initialization for sine startup
is required. Select the operating mode “Block, HallFX, Closed Loop” and enter the parameters as
shown in Figure 14

. Please check the option “Enable speed control”. The speed control should be
enabled. If the speed control is disabled, the motor will start without ramp up. Please keep in mind to
press the “Set” buttons. Thereafter, press the “Start” button and the motor will ramp up with block
commutation. If the motor is running the initialization is successful. Then stop the motor by pressing
the “Stop” button und select the operating mode “Sine, HallFX, Closed Loop”. Thereafter, press the
“Start” button and the motor will ramp up with sinusoidal commutation and will run by using the
sensorless
