speed control, be sure that the “Duty cycle ref” is unequal to zero. Otherwise the motor will stop.
Please note if the speed control is disabled, the motor will start without ramp up.
Please take into account that the maximum PWM duty cycle is limited to the value of 93%. This is
necessary because the BEMF voltage is incapable of measurement clearly above the PWM duty cycle
of 93%.

Configuration of operating mode “Block, HallFX, Closed Loop”
In this mode the parameters “Maximum current” and “Pole pairs” are required only. In addition, some
parameters for closed loop ramp up are necessary. The value “Speed” is the end point of ramp up.
The value “Acceleration” is the angle acceleration for startup. The direction can be changed by setting
CCW or CW. (Figure 11)

startup parameters (“Block, HallFX, Closed Loop”)
Thereafter, you can configure the current
controller. The first parameter “Current Ref.”
defines the maximum current value for startup.
The parameter “Current Time” is the regulation
time of the current controller. The last
parameter “Current Control Kp” is the
proportional gain of the controller. Now, enter
the speed reference value (Speed Ref.) and
the speed control time (Speed Ctl. Time). The
speed control time is given in milliseconds
(ms). In each time interval the PWM duty cycle
counts up or down by a value of 1/16 %. You
can change these parameters at any time.
Please keep in mind to press the “Set” button.

Thereafter, press the “Start” button and the motor will ramp up via closed loop current control and will
run by using the BLDC back EMF commutation hallFX™. When pressing the button “Stop”, the motor
will stop. In order to change the motor speed you can enter the new speed reference (Speed Ref.) by
pressing the button “Set” (Figure 10, page 16). Thereupon, the motor will accelerate and decelerate
respectively.
In addition you can disable the speed control by deactivating the option “Enable speed control” (Figure
10, page 16). In this case you can enter the PWM duty cycle (Duty cycle ref.) by pressing the button
“Set”. If you disable the speed control, be sure that the “Duty cycle ref” is unequal to zero. Otherwise
the motor will stop. Please note if the speed control is disabled, the motor will start without ramp up.
Please take into account that the maximum PWM duty cycle is limited to the value of 93%. This is
necessary because the BEMF voltage is incapable of measurement clearly above the PWM duty cycle
of 93%.
6.4.3
Configuration of operating mode “Block, Hall Sensor”
In this mode no ramp up procedure is necessary. Only the parameters “Maximum current” and “Pole
pairs” are required (Figure 13). The direction can be changed by setting CCW or CW. If the required
parameters are defined, enter the speed reference value (Speed Ref.) and the speed control time
(Speed Ctl. Time). The speed control time is given in milliseconds (ms). In each time interval, the
pairs” are required (Figure 13). The direction can be changed by setting CCW or CW. If the required
parameters are defined, enter the speed reference value (Speed Ref.) and the speed control time
(Speed Ctl. Time). The speed control time is given in milliseconds (ms). In each time interval, the
