5.2 Encoder specifications
1) Supply voltage: 12 V or 5 V, depending on the type of the board;
2) 2 quadrature channels (90º) + zero pulse with complementary outputs (differential):
signals A, A, B, B, Z and Z;
3) Linedriver
or
Push-Pull
4) Electronic circuit isolated from encoder frame;
5) Recommended number of pulses per revolution: 1024ppr;
6) Maximum allourd frequency = 100 kHz.
5.2.1 External power supply specifications for output signals
- Voltage: 5V to 15V.
5.3 Encoder connection
5.3.1 External power supply
Optionally, the external power supply for XC8 can also be connected via XC4 or XC5
connectors:
- EBA Board - Connector XC4 pins19 and 20.
- EBB Board - Connector XC5 pins 19 and 20.
5.3.2 Signals cables
The signals connection must be made with balanced shielded cable, appropriate for
differential signal operations. The signal cables must be installed separately from the other
wirings (power, control cables, etc). Always maintaining a minimum distance of 10 in (25
cm) and if possible, installing them inside a metallic conduit.
EBA and EBB Extension Boards have the same connector for input signals named XC9 (fig.14).
Encoder
Maximum recommended length: 330 ft (100m)

5.3.3 Incremental encoder input signals
The sequence of the input signals and the respective pin position, in the connector XC9, is
described on fig. 15. Also the sequence of signals is described on fig. 16.
