C.3.4 Nine-Lead Connector
This connector provides access to non-motion signals from the ESP6000
controller card. Connector pin-outs are listed in Table C.3-5, and function-
ally described in the following paragraphs.
Table C.3-5 — Nine-Pin Connector Pin-Outs
+12V (250mA maximum)
+12V supply available from the PC.
–12V (250mA maximum)
–12V supply available from the PC.
+5V (250mA)
+5 volt (250mA maximum) supply from the PC. This supply is provided for
stage home, index, travel limit, and encoder feedback circuitry.
DGND
Digital ground.
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.
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. When connected to the
UniDrive6000 this output resets all driver channels.
