III.6 Encoder emulations
III.6.1 Incremental-encoder interface (X5)
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 cylic-absolute signals
of the resolver or encoder.
Incremental-encoder compatible pulses are generated from this information.
Pulses are output on the SubD-connector X5 as two signals, A and B, with 90° phase difference
and a zero pulse.
The resolution can be changed with the RESOLUTION parameter:
256/512/1024 pulses per turn for Feedback=Resolver
2048/4096 pulses per turn for Feedback=EnDat or HIPERFACE
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 drivers are supplied from an internal supply voltage.
PGND must always be connected to the controls.
