Setting the parameters:
The following can be set in the “Encoder Emulation” window in the commissioning software:
} Position of the zero pulse within one mechanical revolution (NI-OFFSET parameter)
} Resolution (before multiplication) in counts/revolution
} ENCMODE = 1: Incremental encoder compatible signals from the resolver or SinCos
encoder
} ENCMODE = 3: Encoder signal from X1 is available at X5

Output of SSI signals
Functions:
With this encoder emulation, positional data for the SSI interface is prepared from the exist-
ing output signals from the resolver or SinCos encoder.
