Description
This parameter sets the method used for finding commutation.
0 = Standard wake and shake
Two iterations are used to find the correct angle in this mode. Coarse (current mode) and fine (velocity mode) iterations are done in a loop (WS.NUMLOOPS times). The average angle of all loops is calculated and used.
1 = Commutation alignment by fixed commutation vector (Zero Method)
The motor poles are set to 0, current mode is activated, and WS.IMAX is applied. The angle in which the motor settles is used for commutation. Other settings are restored (such as motor poles and operation mode).
2 = Auto Commutation
The motor phase is set to zero, and the motor is excited with varying magnitudes at various frequencies to determine the correct commutation angle.
-
- This mode is “automatic” meaning it requires no configuration by the user. However, it takes the longest of the Wake and Shake modes.
