The inverter supports the following functions:
● RT
● IRT: The inverter forwards the clock synchronism, but does not support clock
synchronism.
● MRP: Media redundancy, impulsed with 200 ms. Requirement: Ring topology
● MRPD: Media redundancy, bumpless. Requirement: IRT and the ring topology created in
the control
● Diagnostic alarms in accordance with the error classes specified in the PROFIdrive
profile.
● Device replacement without removable data storage medium
● Shared Device for Control Units with fail-safe functions
