These figures relate to CF cards with a capacity of 1 GB. If the "Upgrade SIMOTION devices"
function is used, the downgrade option requires CF cards with double the memory requirement for
"each switch position". The 300 MB persistent memories can therefore only be achieved with
CF cards with at least 1 GB memory capacity.

Explanation:
●
0.5 ms in conjunction with SINAMICS S120 (incl. SINAMICS Integrated / CX32-2)
●
0.25 ms in conjunction with SERVOfast and IPOfast for high-speed I/O processing or high-
performance hydraulic applications. The sensors and actuators are connected via high-speed
PROFINET IO I/O modules.
