Description
The subindices have the following function:
- 00h: Value="1" to "n", where "n" is the number of existing feedbacks.
- nh:
Subindex n contains a bit mask for the respective feedback n. The bits have the following meaning here:
- Bit 0: If the bit is set to "1", feedback n is used for position control.
- Bit 1: If the bit is set to "1", feedback n is used for speed control.
- Bit 2: If the bit is set to "1", feedback n is used for the commutation in Closed Loop.
Subindex 01h always corresponds to the first (and always existing) sensorless feedback.
Which feedback the controller takes into account for the individual controllers (commutation, speed, position) is implicitly specified by the order of the feedbacks.
The search always begins with feedback 2 and continues in ascending order until all existing product-specific feedbacks have been queried. If a feedback is found whose parameterization is set, it is assigned to the corresponding controller and the search ended.
