Operating status
Byte 8. This byte is intended to give information on the Encoder internal
parameters, in other words it informs on the statues of DDLM_Set_Prm byte 10
Operating parameters (refer to section “6.4.1 Byte 10 - Operating parameters”).
In the example of Figure 2: 8A hex = 10001010 bin, that is:
bit 0 = 0:
Code sequence = clockwise rotation
bit 1 = 1: Class 2 functionality = enabled
bit 2 = not used
bit 3 = 1:
Scaling function control = enabled
bit 4 … 6 = not used
bit 7 = 1:
Exchange type = Po velocity information transmission
For any information on the meaning of the individual bits in the Operating
status byte refer to the “Profibus-DP Profile For Encoders” document.
Encoder type
Byte 9. This byte is intended to give information on the Encoder type. The value
is expressed in hexadecimal format. In the example of Figure 2: 01 hex = “Multi-
turn absolute rotary encoder”. For any information on the meaning of the
Encoder type byte refer to the “Profibus-DP Profile For Encoders” document.
Singleturn resolution
Bytes 10 … 13. These bytes are intended to give the number of measuring steps
per revolution that are output for the absolute single-turn position value
(physical single-turn resolution). In the example of Figure 2: 00 01 00 00 hex =
65536 dec, 16-bit physical single-turn resolution. For any information on the
meaning of the
Singleturn resolution bytes refer to the “Profibus-DP Profile For
Encoders” document.
Number of distinguishable revolutions
Bytes 14 and 15. These bytes are intended to give the number of distinguishable
revolutions that the encoder can output. In the example of Figure 2: 40 00 hex,
i.e. 16384 revolutions. For any information on the meaning of the
Number of
distinguishable revolutions bytes refer to the “Profibus-DP Profile For Encoders”
document.
