Function
The STATE-BUS is a device-specific bus system which is designed for Lenze controllers only. The
function block STATE-BUS acts on the terminals X5/ST or reacts on a LOW signal at these terminals
(multimaster ability).
l
Every connected controller can set these terminals to LOW signal.
l
All connected controllers evaluate the signal level at these terminals and control the function
blocks which are internally configured.
l
Up to 20 controllers can be connected.
Stop!
Do not apply an external voltage at terminal X5/ST.
