SLVSD14A June 2017 – June 2020 DRV10983-Q1
Note that the FG output reflects the driving state of the motor. During normal closed-loop behavior, the driving state and the actual state of the motor are synchronized. During open-loop acceleration, however, this may not reflect the actual motor speed. During a locked-motor condition, the FG output is driven high.
The DRV10983-Q1 device provides three options for controlling the FG output during open loop, as shown in Figure 43. The selection of these options is determined by the FGOLSel[1:0] setting.
