Encoder A(–) Input
The A(–) input is pulled-up to +5 volts and pulled down to ground with
1KΩ resistors. This facilitates both single- and double-ended signal han-
dling into a 26LS32 differential receiver. The A(–) encoder encoded signal
originates from the stage position feedback circuitry and is used for
position tracking.
Encoder B(+) Input
The B(+) input is pulled-up to +5 volts with a 1KΩ resistor. The signal is
buffered with a 26LS32 differential receiver. The B(+) encoder encoded
signal originates from the stage position feedback circuitry and is used for
position tracking.
Encoder B(–) Input
The B(–) input is pulled-up to +5 volts and pulled down to ground with
1KΩ resistors. This facilitates both single- and double-ended signal han-
dling into a 26LS32 differential receiver. The B(–) encoder encoded signal
originates from the stage position feedback circuitry and is used for
position tracking.
Encoder Ground
Ground reference for encoder feedback.
Home Input
This input is pulled-up to +5 volts with a 1KΩ resistor by the controller.
The Home signal originates from the stage and is used for homing the
stage to a repeatable location.
Index(+) Input
The (+)Index input is pulled-up to +5 volts with a 1KΩ resistor by the
controller and is buffered with a 26LS32 differential receiver. The (+)Index
signal originates from the stage and is used for homing the stage to a
repeatable location.
Index(–) Input
The (–)Index input is pulled-up to +5 volts and pulled down to ground with
1KΩ resistors by the controller. This facilitates both single- and double-
ended signal handling into a 26LS32 differential receiver. The (–)Index
signal originates from the stage and is used for homing the stage to a
repeatable location.
