Axis Ch. 6 Input A
This input is hard-wired to the 100-pin Axis-6 encoder channel A(+) input.
Therefore, this input can only be used if five (5) (or fewer) axes of motion
are incorporated. The single-ended A input is pulled-up to +5 volts with a
1KΩ resistor. The signal is buffered with a 26LS32 receiver. The A quadra-
ture encoded signal originates from external feedback circuitry and is used
for position tracking.
Axis Ch. 6 Input B
This input is hard-wired to the 100-pin Axis-6 encoder channel B(+) input.
Therefore, this input can only be used if five (5) (or fewer) axes of motion
are incorporated. The single-ended B input is pulled-up to +5 volts with a
1KΩ resistor. The signal is buffered with a 26LS32 receiver. The B quadra-
ture encoded signal originates from external feedback circuitry and is used
for position tracking.
Auxiliary Ch. 7 Input A(+)
The A(+) input is pulled-up to +5 volts with a 1KΩ resistor. The signal is
buffered with a 26LS32 differential receiver. The A(+) quadrature encoded
signal originates from external feedback circuitry and is used for position
tracking.
Auxiliary Ch. 7 Input A(–)
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(–) quadrature encoded
signal originates from external feedback circuitry and is used for position
tracking.
