Note:
By ticking the auto-check boxes, you can configure the operation mode of the single half
bridge outputs. The options available are:
●
●
●
●
●
●
In the right side of the window you can set other bridge parameters:
●
●
●
The overcurrent protection threshold is fixed.
Finally to enable the bridges, click on "Enable motors 3 and 4" and move the PWM sliders to
a percentage different to the 0 default value.
To put the bridges in parallel it is necessary to tick the "motors 1 and 2 paralleled" auto-
check box: output DC3+ and DC4+ is shorted together and so DC3- and DC4- also. The
resulting bridge uses the driving logic of bridge 3 as mentioned above.
If you want to drive a stepper motor click one of the buttons connected to the "stepper
controller" box as shown in
selected. Push one of the "Set configuration and enable" buttons.
Figure 22. Bridge 3 and 4 configuration: stepper controller
'0': Hold the output low (low side power on)
'1': Hold the output high (high side power on)
HiZ: high impedance status (high and low side off)
PWM_1-0: the output is alternatively in status '0' or '1'
PWM_HiZ-0: the output is alternatively in status 'HiZ' or '0
PWM_1-HiZ: the output is alternatively in status '1' or 'HiZ'.
