With long resolver cables, a phase shift occurs between the exciter signal and tracks A/B due to the line inductance. This effect reduces the amplitude of the resolver signals after demodulation and inverts their phase in the case of very long line lengths.
The phase shift can be equalized with parameter P 0565 ENC_CH2_LineDelay. By way of parameter
P 0566 ENC_CH2_Amplitude the amplitude can additionally be varied in the range -100%...+30%.
The resolver signals are plotted with the oscilloscope dependent on the setting of parameters
P 0565 and P 0566. When the phase shift has been equalized, the settings can be saved.

NOTE: Cable lengths > 50 m only on request. |
