Table 9 - Encoder Sample Interval Settings
[Encdrx Error] indicates the error status of the encoder when there is an error.
The bits for [Encdrx Error] are broken down as follows:
•
Bit 0 - “EncdrMissing”
•
Bit 1 - “Quad Loss”
•
Bit 2 - “Phase Loss”
•
Bit 3 - “Phase Level”
The encoder block generates speed feedback, seen in [Encdrx Spd Fdbk].
[Encdrx Spd Fdbk] is in units of RPM.
The encoder block also generates a position feedback, seen in [Encdrx Position].
[Encdrx Position] is in counts.
