DRV8426: Non-circular 1/2step and 1/2step

Hi Expert,

Could you please let me know the consern for system usecase in case of using Non-circular 1/2step?

The torqe will be 1.41（√２）at 45°, 135°, 225° and 315° against 0°, 90°, 180° and 270°.

Generally, do you have any consern for motor control?  oscilation, thermal issue and somting like that?

Also, do you have any data for difference between Non-circular 1/2step and 1/2step(constant torque : 71% at 45deg) ? 

Thanks
