8.6.1 Absolute value encoder - raw data
For dia
nosis, you can check the value transmitted by the absolute value encoder via
parameter
Abs. Encoder Raw Data 1267.
Dependin
on the encoder technolo
y used, the actual value parameter is built up as
follows:
Hiperface
Position
Binary
EnDat 2.1
Position
Binary
SSI
dditional bits (Hi
h) : Position :
dditional bits (Hi
h)
Binary Binary raw
(not converted)
Binary
Note: The colons are added in the case of (parameterized) SSI encoders for
better readability in the display, they do not form part of the transmitted
telegram.
The colons are added according to the configuration of parameters
SSI:
rro
-/Extra-Bits (Low) 1269, SSI: Error-/Extra-Bits (High) 1270 and
its/Turn 1271, Bits Multiturn 1272.
Note:
he positionin
value in SSI is not valued. When it comes to dia
nosis,
consider the codin
system used by the encoder (Gray code or binary
code).
SinCos
SinCos encoders do not use absolute values. The actual value parameter remains emp-
ty.
8.6.2 Actual position
ct. position 1108
shows the current actual value (position) in user units [u] in positioning configurations
