Incremental encoder simulation - A quad B position output (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 cyclic-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 (lines before quadrature) can be changed with the RESOLUTION parameter:
Encoder function (ENCMODE)
ROD (1)
ROD interpolation (3)
You can also adjust and store the position of the zero pulse within one mechanical turn
(parameter NI-OFFSET).
The drivers are supplied from an internal supply voltage.
PGND must always be connected to the controls.
The max. admissible cable length is 10 m.
