Description: Set the output phase sequence. This function virtually swaps the output phases, which can be used to change the direction
of motor rotation without having to physically rewire motor cables.

P 4.2.1.2 Number of Pole Pairs
The synchronous speed of a motor can be calculated when the supply frequency and number of pole pairs are known. The formula to
calculate the synchronous speed of the motor (ns) with supply frequency (f ) and number of pole pairs (p) is as follows:
A

While the frequency is determined by the grid or the AC drive, the number of poles is determined by the way the stator inductors are
connected. Pole pairs (p) or pole number and synchronous motor speed lists the number of poles corresponding to synchronous speed
(n0) at 50 Hz and 60 Hz supply.
