Analog output

output actual values and other internal common rectifier quantities.
Analog output:
Connecting-up:
Refer to "Control terminal strip", Section 3.3
Parameterization:
Also observe "Function diagram, analog output CUR", Section 4.4!
♦
Enter the parameter number (0 to 999) whose value is to output, in P655 "CUR-AA actual values".
♦
Set the analog output gain factor in P656 "CUR-AA gain".
(setting range: -320.00V to +320.00V / pre-setting: +10.00V ⇔ gain of 1)
♦
Set the offset in P657 "CUR-AA offset".
(setting range: -100.00V to +100.00V / pre-setting: +0.00V ⇔ no offset)
The following is obtained for the calculation from the "Function diagram, analog output CUR":
Pre-assignment (gain of 1 and no offset):
The parameter value in [%] for the appropriate parameter number can be taken from the parameter list,
