XPS-D Controller Start-Up Manual
+ Travel limit This input is pulled-up to +5 V with a 2.2 kΩ resistor by the controller and represents
the stage positive direction hardware travel limit.
- Travel limit This input is pulled-up to +5 V with a 2.2 kΩ resistor by the controller and represents
the stage negative direction hardware travel limit.
Encoder A & /A These A and /A inputs are differential inputs. Signals are compliant with RS422
electrical standard and are received with a MC3486 differential line receiver. A resistor
of 120 Ω adapts the input impedance. The A and /A encoder signals originate from the
stage position feedback circuitry and are used for position tracking.
Encoder B and /B These B and /B inputs are differential inputs. Signals are compliant with RS-422
electrical standard and are received with a MC3486 differential line receiver. A resistor
of 120 Ω adapts the input impedance. The B and /B encoder signals originate from the
stage position feedback circuitry and are used for position tracking.
Index & /Index These Index and /Index inputs are differential inputs. Signals are compliant with RS422
electrical standard and are received with a MC3486 differential line receiver. A resistor
of 120 Ω adapts the input impedance. The Index and /Index signals originate from the
stage and are used for homing the stage to a repeatable location.
GND Ground reference.
Origin This input is pulled-up to +5 V with a 2.2 kΩ resistor by the controller. The Origin
signal originates from the stage and is used for homing the stage to a repeatable
location.
+5 V (0.25A max.) +5 VDC supply is available from the driver. This supply is provided for stage home,
index, travel limit, and encoder feedback circuitry.
