The following sections describe how to set the relevant control parameters.
Setting desired value 1...3
You can use this parameter to set up to 3 desired voltage values U
Ref
. The
desired voltage value is specified as a fixed value. The desired value 1 is the
default desired value. Desired values 2 and 3 are activated if there is a con-
tinuous signal at factory-preset control inputs X4:17 or X4:18 provided you
have programmed these previously. If there is a signal at several control in-
puts at the same time, desired value 2 is activated.
The device provides the following ways of changing the desired voltage val-
ue during operation:
▪ Using the control parameters menu item via the operating screen
▪ Using binary inputs
▪ Using control system protocols if a communication card is ready for op-
eration
