Secondary Feedback; Overview Of Secondary Feedback (Dual Loop Control) - Servotronix CDHD2S User Manual

Application Setup
When checking the sine and cosine signals of the sine encoder, you need to calculate as: signal
× 0.00001883 (1/32768
The resulting data diagram in the Rang screen will look similar to the figure below. This diagram
shows the signal level (expressed in volts) of the actual input signal. As expected, the sine encoder
signal is close to 1V peak-to-peak.
When checking the sine and cosine signals of the resolver, you need to calculate as: signal
× 0.0000939 (1/32768
The resulting diagram in the Rang screen will look similar to the figure below. This diagram
shows the signal level (expressed in volts) of the actual input signal.
