2.16: Outputs, XE2/XP2/800-1782/800-1808
XE2/XP2/800-1808 has 7 programmable digital outputs, while the 800-1782 has 5. OUT1~5 are
general-purpose outputs. The 800-1782 does not utilize OUT 4~5. OUT6 and OUT7 are
specifically designed as brake outputs for axis A and B respectively, but can be programmed to
perform other functions. For a list of digital output functions, see the CME 2 User Guide. There are
no analog outputs in XE2/XP2/800-1782/800-1808.
Opto-isolated OUT1~OUT5 are connected on J9. Brake outputs OUT6 and OUT7 are on J5.
OUT1~OUT5 are opto-isolated MOSFET switches, each with a series resistor and Zener clamping
diodes across the outputs allow driving of resistive-inductive (R-L) loads without the need for
external flyback diodes.
Brake outputs (OUT6 and OUT7), are open drain MOSFETs with internal flyback diodes
connected to the +24 Vdc input. Details are described in Brake Operation (p. 35)
