Default BiSS C Interface Setting of ITF-21-BISS-MIT
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.
Number of bits of position
data
12 to 32 bits
The setting above in general can support most of the situation if the encoder cable requirement is
≤
20m.
For special situations which violates the requirement above, please enquire Akribis System sales.
Basically, the adapter can support any situation if the requirement of Max Allowable of BiSS C Cycle of Adapter of 102
μs
is adhered.
