6. Control of the output voltage via analog input
In the case of feedback of the output signal is possible to readjust
The output voltage is returned via transformer to the analog input.
For this feedback several options are available:
DC Voltage
If is available the output voltage as DC voltage signal 10V then it can be read at analog
GB
input on the ACU base unit or at analog input of an expansion module (except EM-RES-03).
D
AC voltage single phase
A transformer returns the output voltage to a bipolar analog input of an expansion module
(except EM-RES-03)
AC voltage two phases
Two AC signals offset by 120 ° are back to the inputs X412 SIN +/- and COS +/ -of the
module EM-RES-03. The signals must be scaled to the permissible voltage level.
