Hi Krushal,
I will be controlling the driver via I2C. It's indicated in the datasheet that a maximum speed is when SpdCtrl[8:0] is set to 0x01FF (511). Using equation 7, this shows a 4-pole motor to have a maximum speed of 1530 RPM. Is it possible to set MotorSpeed1 and 2 higher than 0x01FF? This seems to be the limiting factor in the output.
Thanks,
Matt
