2.2.2 Sine encoders (SIN/COS encoders)
(SK 540E and above)
The use or function of sine encoders is comparable with that for incremental encoders. However, the
encoder provides sine wave signals instead of digital pulses.
The voltage source can be an external source or the internal voltage (according to the frequency inverter
version: 12V /15V /24V).
