Analog output

Overview
An analog output can either output a voltage or a current signal. A signal interconnection
defines the function of the analog output. Based on an adjustable characteristic, the converter
converts an internal percentage value into a voltage or current signal.

Description of function
The analog output has the following properties:
• Type can be selected
To adapt the analog output to the external control system, the analog output can be operated
as a current output or voltage output. Parameter p0776 defines the analog output type.
• Function can be set
The interconnection of a numeric signal source of the converter with parameter p0771
defines the function of an analog output.
Frequently used numeric signal sources of the converter:
• Smoothing can be set
Parameter p0773 effects a smoothing of the output signal using a PT1 filter. This allows
strong fluctuations or short-term peaks to be suppressed.
• Absolute-value generation can be set
Parameter p0775 represents the amount of the output value.
• Inversion of the analog output signal
Binary signal sink c0782 inverts the analog output signal.
