4.11.16.9.4 SSI encoder - Configuration registers
4.11.16.9.4.1 SSI position values
Name:
Encoder01 to Encoder02
The two SSI encoder values are displayed as 32-bit position values. The SSI position values are generated syn-
chronously with the X2X cycle.

4.11.16.9.5 Minimum cycle time
The minimum cycle time defines how far the bus cycle can be reduced without communication errors occurring.
It should be noted that very fast cycles decrease the idle time available for handling monitoring, diagnostics and
acyclic commands.
Minimum cycle time
128 μs
4.11.16.9.6 Maximum cycle time
The maximum cycle time defines how far the bus cycle can be increased without internal counter overflows causing
module malfunctions.
Minimum cycle time
16 ms
4.11.16.9.7 Minimum I/O update time
The minimum I/O update time defines how far the bus cycle can be reduced while still allowing an I/O update to
take place in each cycle.
Minimum I/O update time
128 μs
