4.3.7 Encoder emulation
Encoder emulation 4- ][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_X1
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
` Default count direction: Upwards (facing the motor axis when rotating
clockwise)
