What if any software changes are necessary when changing from a wye connected motor to a delta connected BLDC motor when using the ST72141 processor in sensorless mode?

Hello,
No changes are needed in the software between a star and delta connections. Only the delay coefficient (which determines the delay between the back-emf zero-crossing detection and the next commutation) needs to be updated. Best Regards
