Output signals for a higher level position controller are generated from
signals from the resolver or a SinCos encoder. The position of the motor
shaft is calculated in the servo amplifier from the cyclical-absolute sig-
nals from the resolver or SinCos encoder:
Signals are incremental encoder compatible

Signals for the SSI interface

Output of incremental encoder signals
Functions:
With this encoder emulation, a total of six tracks are generated from the
existing output signals from the resolver or SinCos encoder; a higher
level control system uses these tracks for positioning. These six tracks
are track A, B and NI (zero pulse) and their inverted signals A\, B\ and
NI\.
Parameter setting:
The following can be set in the "Encoder Emulation" window in the com-
missioning software:
Position of the zero pulse within one mechanical revolution (NI-OFF-
