The symmetrical encoder signals (differential track signals) for Track 1, Track 1N,
Track 2, Track 2N, Track Z, Track ZN are detected and processed through differential
input stages in a voltage range from approx. 3 V ... 24 V and are output to the
terminals according to Fig. 15 as the signals TRACK1OUT, TRACK1NOUT,
TRACK2OUT, TRACK2NOUT, TRACKZOUT, TRACKZNOUT for further use at a
voltage level of
DC +5 V. Output at the 15 V or 24 V voltage level is in preparation. The encoder track
signals are monitored for wire break. The LEDs ARDY (Track 1 / Track 1N), BRDY
(Track 2 / Track 2N), ORDY (Track Z / Track ZN) ... indicate that the track signals are
intact, see Fig. 16.
If symmetrical encoder signals are connected, the two hook switches S20a and S20B
are in position 1. Asymmetrical encoder signals cannot be processed directly.
The zero pulses (Track Z / Track ZN) of the incremental encoder are not processed at
the present time and need not be connected.
When a 5 V encoder supply voltage is used, connection of a sense signal at E83 :X10
terminal :12/:14 allows compensation for voltage drops. Through internal calibration
the voltage actual value is processed and the voltage drop is controlled within the
adjustment range (TTL level).
The maximum cable length for connecting an incremental encoder however is also
limited by the maximum frequency which can be transmitted. The notes on connection
must be observed.
