Newport XPS-Q8 - Three Phase AC Brushless Driver XPS-DRV02

XPS-Q8 Controller Appendix
26LS32 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 26LS32
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
26LS32 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.
Encoder ground Ground reference for encoder feedback.
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 (DRV01: 250 mA Maximum) A +5 V DC supply is available from the driver.
This supply is provided for stage home, index, travel limit, and
encoder feedback circuitry.
Limit ground Ground for stage travel limit signals. Limit ground is combined
with digital ground at the controller side.
Shield GND Motor cable shield ground.
Brake + (available only on DRVM board) Voltage command (24 V or 48 V: strap on
the driver board) to drive the brake.
Brake – (available only on DRVM board) Reference of the above voltage command.
Tachometer + & Tachometer – These inputs are used to receive tachometer voltage
information. This voltage depends on the output voltage rating of
the employed tachometer.
