SLVSCP6H July 2014 – June 2020 DRV10983
The DRV10983 converts the various types of speed command into a speed command value (SpeedCmd) as shown in Figure 39. By reading SpeedCmd, the user can observe PWM input duty (PWM digital mode), analog voltage (analog mode), or I2C data (I2C mode). This value is calculated as shown in Equation 13.
Equation 13 shows how the speed command as a percentage can be calculated and set in SpeedCmd.
