Amplifier Enable Output, Axis 1, 2, 3, 4
Open-drain output with 1KΩ pull-up resistor to +5 volts. This output is
asserted active True when the axis is in the motor ON state and False for
the motor OFF. The actual TTL level is user-configurable.
Analog Ground
Servo digital-to-analog (DAC) ground.
Digital Ground
Ground reference used for all digital signals.
Encoder A(+) Input, Axis 1, 2, 3, 4
The A(+) input is pulled-up to +5 volts with a 1KΩ resistor. The signal is
buffered with a 26LS32 differential receiver. The A(+) encoder encoded
signal originates from the stage position feedback circuitry and is used for
position tracking.
