The EVAL6460 controlled by the EVAL_IBU-STR7 AN3097
22/34 Doc ID 16599 Rev 2
In this window select "Config" under the "Stepper controller" rectangle, the "Bipolar Stepper
Configuration" appears. In this window it is possible to set some parameters:
● Decay mode
● Offtime
● Blanking time
● Voltage reference for the current control
● Direction
● Driving mode
● Clock source
Configure the stepper controller as shown in Figure 23.
Figure 23. Bipolar stepper configuration window
Then in the L6460 block diagram window push the "GPIOs" button and configure GPIOs 12
and 13 as indicated in Figure 24. GPIO 12 is used as the stepper sequencer clock input, for
this purpose set the external connection between GPIO 12 and 13.
In the GPIOs window push the "Aux PWM3" button on the bottom left-hand side then
configure the PWM generator changing the high and low time and the period. The last
determines the stepper's speed.
