Signal adaptation
Finer resolutions than the power-of-two format can be realised by connecting an FB (e.g. CONV3 or
CONV4).
Example:
The FB CONV3 converts the speed signal into a quasi-analog signal. The conversion is done
according to the following formula:
CONV3-OUT [%] = f[Hz]⋅

Stop!
If C0540 = 0, 1, 2, 3 and a feedback system C0025 > 10, you must not use the digital frequency input
X9 anymore.
