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 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.
