1)
In accordance with generally recognized testing principles, test authorities typically stipulate that the
applic
ation must ensure the monitored unit performs a movement at least once within the space of
24hours. This movement must generate a signal change on the encoder system, which can be used as a
basis for detecting the relevant errors.
1)
E.g., shared use of encoder signals for electronic commutation of the drive system.
2)
Sin_Ref and Cos_Ref are DC voltages, typically 2.5VDC.
4)
Sin– and Cos– are the inverted voltages of Sin+ and Cos+ respectively.
