10.2 Speed fbk loss alarm according to the type of feedback

Note !
For the correct interpretation of the cause of the alarm trigger, it is necessary to transform the hex code indicated in parameter 15.13 SpdFbkLoss code,
PAR 2172 , in the corresponding binary and verify in the encoder table that the active bits and related description are used.
Example with encoder Endat:
PAR 2172 = A0H
In the table "Speed fbk loss [22] alarm with absolute encoder EnDat" A0 is not indicated in the value column.
A0 should be contemplated as a bitword with meaning A0 -> 10100000 -> bit 5 and bit 7 . The following causes simultaneously intervene:
- Bit 5 = 20H Cause: the SSI signal interferences cause an error in the CKS or parity.
- Bit 7 = 80H Cause: The encoder has detected an incorrect operation and communicates it to the converter through the Error bit. Bits 16..31 present the
type of incorrect encoder operation detected.
The value is displayed in hexadecimal format on the optional and standard keypad.
