Example:
Executing special command 5 will start a PWM of 28% duty
cycle (28% on, 72%off) until special command 6 is executed.
Executing special command 15, will connect the ballast
resistor for a period of 0.6 seconds, and then disconnect it.
SE-test single pulse: Short
Test PWM/time: 28% / 0.6s@100%
Selecting Long single pulse will change the value in the
selectable list to:
28% / 5s@100%.
Executing special
command 5 will start a PWM of 28% duty cycle (28% on,
72%off) until special command 6 is executed. Executing
special command 15, will connect the ballast resistor for a
period of 5 seconds, and then disconnect it
SE-test single pulse: Long
Test PWM/time: not changed
manually
8.4.6 Configuring pre-heating
There are two configuration parameters for the pre-heating
•
I pre-heat: the current that will used for pre-heating: 1/8 to 8/8 of I con eff (defined in reg. 0xC5).
Select the desired current from the dropdown list.
•
Current mode: Select whether the speed or torque parameters are used during pre-heating. It is
recommended to select Speed.
Attention
Single pulse longer than 1s might damage the built-in ballast resistor, depending on the safe
energy voltage.
