D.2. Option
Changes
The -IOPSO3 and -IOPSO4 options are obsolete now that the -IOPSO outputs may be
software configured as either sourcing or sinking.
New Features
•
The pin-out of J205 has changed due to a larger connector being added.
Summaries of the changes follow, see Table D-1 for the complete pin-out.
•
There are now 4 optically isolated user current sinking outputs standard, on
J205. They are set as $OUT8 through $OUT11. This implies that they are
outputs 8 through 11. Outputs 0-7 are on the -IOPSO option.
•
There are now 6 optically isolated user inputs standard, 2 of which are high
speed, user configurable as sourcing or sinking, on J205. They are read as $IN8-
13. This implies that they are inputs 8 through 13. Inputs 0-7 are on the -IOPSO
option.
•
A motor over-temperature thermistor input was added at J207 pin 2.
•
One of the two analog outputs is now available standard on J205, as well as
TB301 of the -IOPSO option.
•
One of the two analog inputs is now available standard on J205, as well as
TB302 of the -IOPSO option.
•
User digital inputs on the -IOPSO options now have two input commons, one
for each set of four inputs at TB305. They are pins 1 and 2 as shown in the
margin.
•
The auxiliary encoder (secondary feedback) may now be configured as an
output, to prevent the user from having to purchase an -IOPSO option for two-
axis laser firing, jumper selectable via JP2-4. This allows it to drive another axis
auxiliary encoder channel for dual axis firing, on J206.
•
A dedicated optically-isolated emergency stop sense input on TB201.
•
Joystick, handwheel and typical ESTOP usage now supported and documented
in the manual for Rev. A Ndrives. These will eventually be added to the ROM's
in .dwg format also.
•
Single and dual axis PSO (Laser Firing) users may now use optically isolated
Output 11 as the firing output, so the -IOPSO option is not required.
•
Manual for Rev. 0 Ndrives have been renamed with "Rev. 0" in filename and is
still distributed with all other Aerotech product manuals.
