Function Description
4.3.7
Encoder emulation
Output signals for additional devices are generated from signals from the resolver or a Sin-
Cos encoder, e.g. for control systems or PMCprotego D. The position of the motor shaft is
calculated in the servo amplifier from the cyclical-absolute signals from the resolver or Sin-
Cos 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 sig-
nals 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\.
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
}
Default count direction: Upwards (facing the motor axis when rotating clockwise)
