EIB 700


    EIB 741, EIB 742

    Encoder inputs

    D-sub connections, 15-pin, female (X11 to X14), for four encoders

    Input signals (switchable)

    1 VPP (11 µAPP upon request)

    EnDat 2.1

    EnDat 2.2

    Voltage supply for encoders

    5.12 V DC ± 0.15 V; max. 450 mA per channel

    Overcurrent protection (automatic switch-off, resettable) at 550 mA

    Input frequency

    ≤ 500 kHz

    Subdivision factor


    Signal adjustment

    Automatic adjustment of offset, phase and amplitude

    Cable length1)

    ≤ 150 m

    ≤ 150 m

    ≤ 100 m

    Data register for measured values

    48 bits (only 44 bits are used)

    Interval counter

    • Derived from axis 1 (only 1 VPP),
    • Interpolation factor can be set from 1-fold to 100-fold
    • Can be used as trigger source or additional counting axis

    Measured-value memory

    Typically 250,000 position values per channel

    Measured-value trigger2)

    Storage of the measured values of the four axes alternatively through external or internal trigger.


    • Signal via trigger input
    • Software command (over Ethernet)


    • Timer
    • Interval counter
    • Reference pulse of the respective axis (from axis 1 also possible for other axes)

    Trigger input3)

    D-sub connections, 9-pin, male; differential inputs as per RS-485 (terminating resistors can be activated)

    Trigger output3)

    D-sub connection, 9-pin, female, 4 differential inputs as per RS-485

    Access to measured values

    Depends on the selected operating mode (see separate table)


    • Driver software for Windows, Linux and LabVIEW
    • Program examples
    • EIB application software

    Data interface

    Ethernet as per IEEE 802.3 (max. 1 GB) (data cable must be suitable)

    Network address

    Automatic assignment through Dynamic Host Configuration Protocol (DHCP) or manual assignment

    Operating temperature

    0 °C to 45 °C (storage temperature –20 °C to 70 °C)

    Power supply

    EIB 741: 100 V to 240 V AC (± 10%), 50 Hz to 60 Hz (± 2 Hz), power consumption approx. 30 W

    EIB 742: 24 V DC (–15 %/+20 %), ≤ 2 A

    1) The supply voltage range of the encoder must be maintained; specified cable length applies when HEIDENHAIN cables are used.

    2) Different trigger sources can be assigned to the individual axes.

    3) Can also be used as logical input or output.
