Kollmorgen 07/03 Interfaces
3.6 Encoder emulations
3.6.1 Incremental encoder interface (X4)
The incremental-encoder interface is part of the package supplied.
Select the encoder function ROD (screen page Encoder).
In the servo amplifier, the position of the motor shaft is calculated from the cyclic-absolute signals of
the resolver or encoder.
This information is used to generate incremental-encoder compatible pulses.
Pulses are output on the SubD-connector X4 as two signals, A and B, with 90° phase difference
and a zero pulse.
The resolution can be changed with the ENCOUT parameter:
32/64/128/256/512/1024 pulses per turn for Feedback=Resolver
2048/4096 pulses per turn for Feedback=EnDat or HIPERFACE
8192 pulses per turn for Feedback=EnDat or HIPERFACE up to 3000 rpm
16384 pulses per turn for Feedback=EnDat or HIPERFACE up to 1500 rpm
You can also adjust and store the position of the zero pulse within one mechanical turn
(parameter NI-OFFSET). Because of the compatibility with normal commercial pulse encoders, you
can only set the zero pulse when A=B=1.
The ground reference for the interface is AGND.
This must always be connected to the ground for the control input signals.
