digital I/O connector (JP4) signals. When configured as output, each bit
can source 64mA (maximum). When configured as input, each bit can sink
32mA (maximum).
DSP Reset Output
The Reset output is a TTL-buffered output which represents ESP6000
hardware reset status of the controller itself. When the controller is held
in a reset state this output is a logical LOW. This output can be used to
reset external devices whenever the ESP6000 DSP is reset.
E-Stop Input
The Emergency Stop (E-Stop) input is pulled-up to +5 volts with a 1KΩ
resistor. The incoming signal to this input must be a low-going, TTL-
compatible digital pulse with minimum 10 microsecond duration. This
signal should be debounced so as not to generate multiple E-Stops within a
100 millisecond time period. When this signal is asserted the controller
will perform an Emergency Stop procedure as configured by the user.
When used with the Unidriver6000 motor driver, this signal is coupled to
the Stop All front panel pushbutton.
C.1.5 Analog I/O (26-Pin) JP2 Connector
