Rectifier/Regenerating Unit Operating Instructions
4.3.5 Analog output
1 analog output, which can be parameterized,
at the control terminal strip (board CUR, -X102 / Section 3.3)
to output actual values and other internal rectifier/regenerating unit quantities.
Analog output: - Voltage range: ± 10V
- Resolution: 39mV (8 bits + sign)
- Accuracy: ± 5%
- Smoothing: 20ms
- Output current: max. ± 5mA
- Short-circuit proof and non-floating
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":
