New (page 41): High voltage ride-through
The High voltage ride-through (HVRT) function is similar to Low voltage ride-through, except that it is
used to cope with voltage peaks instead of voltage dips. The function is programmable, and the user
can define when inductive reactive current must be generated. Inductive reactive current helps to
reduce grid overvoltage.
The diagram below illustrates the operation of the function.

New (page 44): Mailbox function
The Mailbox function can be used for parameter read and write operations targeted to either to the
master control unit or inverter control unit. When the function is used, only one communication
adapter is required in the master control unit. The input and output values for the function are in
master control program parameter group
the inverter control unit, an offset of 10000 must be added to the parameter address.
