The ANALOG interface of the DDS 2.1 drive controller serves to
communicate with an NC control equipped with a ±10V analog interface.
The ANALOG interface has therefore been provided with various control
inputs and signal outputs (see Fig. 18).
The ANALOG interface comes in two versions:
– ANALOG interface with incremental encoder emulator
– ANALOG interface with absolute encoder emulator
The incremental encoder emulation enables the output of internal drive
information on position or angle. This information is passed to the
connected NC control as an input signal for actual-value sensing.
Output signals: incremental encoder compatible square-wave signals
(voltage signals)
The absolute encoder emulation enables the output of internal drive
information on position or angle via the SSI (synchronous serial interface)
usual in absolute encoders, thus providing a position actual value for
external use.
