SLVSCP6H July 2014 – June 2020 DRV10983
If the motor is spinning in the reverse direction, the DRV10983 provides several methods to convert it back to forward direction.
One method, reverse drive, allows the motor to be driven so that it accelerates through zero velocity. The motor achieves the shortest possible spin-up time in systems where the motor is spinning in the reverse direction.
If this feature is not selected, then the DRV10983 may be configured to either wait for the motor to stop spinning or brake the motor. After the motor has stopped spinning, the motor start-up sequence proceeds as it would for a motor which is stationary.
Take care when using the feature reverse drive or brake to ensure that the current is limited to an acceptable level and that the supply voltage does not surge as a result of energy being returned to the power supply.
