(1) Default BiSS C Setting:
MA Clock Frequency: 1MHz (1 µs) [Encoder cable length ≤ 20m]
Max allowable acknowledge
duration of BiSS C encoder 35 µs
Max allowable timeout duration 23.5µs + (35 µs – actual ack duration used)
Note: timeout of encoder is usually configurable. Please check
encoder datasheet.
Note:
The default BiSS C setting above in general can support most of the situations as long as the total encoder
cable length requirement is ≤ 20m. For special situations which violates the requirement above and thus
customised firmware is required, please enquire Akribis System sales.
