Chris,
I don't believe I encountered this behavior. Given that you are ~4x the fundamental frequency where the false lock occurs I would have expected varying the PWM by something like 0.05% would have been sufficient to move away from the false lock.
How invested in DRV11873 are you? A newer 12V device in our products in DRV10975, however, it does require I2C interface to configure the motor controller.
I'll think about it a little more and see if I can find any reason that you are having to vary the PWM so much.
Thanks,
Brian
