15-pin D-sub connections (female) (X11 to X14), for four encoders
1 VPP, 11 µAPP
Supply voltage for encoders
DC 5.12 V ±0.15 V; max. 450 mA per channel
Overcurrent protection (automatic switch-off, resettable) at 550 mA
≤ 500 kHz
Automatic adjustment of offset, phase, and amplitude
≤ 150 m
≤ 100 m
Data register for measured values
48 bits (of which only 44 bits are used)
Derived from Axis 1 (only 1 VPP)4),
Configurable interpolation factor from 1-fold to 100-fold
Can be used as a trigger source or additional counting axis
Typically 250 000 position values per channel
Storage of the measured values of the four axes through an external or internal trigger (selectable).
External: • Signal via trigger input • Software command (over Ethernet)
Internal: • Timer and interval counter • Reference pulse of the respective axis (from Axis 1 and other axes)
9-pin D-sub connection (male); differential inputs as per RS-485 (terminating resistors can be activated)
9-pin D-sub connection (female); four differential outputs as per RS-485
Access to measured values
Depends on the selected operating mode (see separate table)
Ethernet as per IEEE 802.3 (10/100/1000 Mbit/s)
Automatic assignment through Dynamic Host Configuration Protocol (DHCP), or manual assignment
213 mm x 152 mm x 42 mm
0 °C to 45 °C (storage temperature: 0 °C to +70 °C)
EIB 741: AC 100 V to 240 V (±10 %), 50 Hz to 60 Hz (±2 %); max. power consumption: 30 W
EIB 742: DC 24 V (–15 %/+20 %), max. 2 A
1) When using HEIDENHAIN cables; the supply voltage range of the encoder must be adhered to.
2) Various trigger sources can be assigned to the individual axes.
3) Can also be used as a logic input or output; 4) Maximum input frequency for referencing: 70 kHz
5) The quality of the data cable between the EIB and PC must be adapted to the transmission rate and cable length.
