CSA31A profile variant "System"
With the "System" profile variant, a 16-bit value and a 32-bit value are transmitted in addition to the bits described in the "Technology" profile variant.
Process value 1 (16 bits)
- Speed (high word)
- Speed (low word)
- Speed (saturated)
- Rotational speed (high word)
- Rotational speed (low word)
- Rotational speed (saturated)
- SCA state
- Bit 0 = SCA1, Bit 1 = SCA2, ... Bit 15 = SCA16. For a description of the bit values, see table byte 5, bit 0 – 3.
- Position (high word)
- Position (low word)
- Position (saturated)
Process value 2 (32-bit)
- Position value
- Speed
- Rotational speed
- Position value encoder 1
- Position value encoder 2
- Position value encoder 3
INFORMATION
The raw position values correspond to the position values sent by the encoders to the safety option for safety-related evaluation.
The speed, rotational speed, and position values are processed in the CSA31A safety option as 32‑bit values.
The position and speed value also includes the parameterized decimal places. Example of a speed with 2 decimal places: v = 1234.56 mm/s. The internal numerical value is 123456. This means that there is a 1 in the high word and 57920 in the low word.
For the speed to be displayed in the low word, the speed with one decimal place must not exceed the value +/- 3276.7 in user unit. If the number range of the low word has an overflow, the value freezes at 32767. This state is referred to as "saturated".
The rotational speed value is indicated in system units. The numerical value is shown in 1E 4 min-1.
