Encoder emulation

Encoder emulation

][Funktion_Encoder_Emu_X1

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

][Funktion_Encoder_Emu_ROD

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-
SET parameter)

Resolution (before multiplication) in counts/revolution

ENCMODE = 1: Incremental encoder compatible signals from the re-
solver or SinCos encoder

ENCMODE = 3: Encoder signal from X1 is available at X5
