Connection of the feedback systems
The feedback systems (linear or rota ry encoders) are connected via SUB-D
HD type 15-pin female connectors: X1 and X2. The latter (for the 2nd axis) is
not available at the 10iE model.
Characteristics of feedback inputs: X1 and X2:
- Power consumption: 250 mA at the +5V input.
- Admits square-wave signal (TTL). (A, B, Io)
- Maximum frequency: 250 KHz, minimum gap between flanks: 950 nsec.
- Phase shift: 90º ±20º, hysteresis: 0.25 V, Vmax: 7V,
maximum input current: 3mA
- High threshold (logic state 1) 2.4V < VIH < 5V
- Low threshold (logic state 0) 0.0V < VIL < 0.55V
