Functionality Quick-Start
Open Loop
If you have an open loop system (No Encoder), after opening the port from
part 2.3-1 you can test movement by entering a value in the increment field and
press either of the
buttons. Be sure that the value is within the confines of
the travel limits. The stage should move and you should see the Calc field change.
Closed Loop
If you have a closed loop system (Attached Encoder), after opening the port
from part 2.3-1, ensure that the controller is in closed loop on the system page
(section 2.3-4h.). Then in the motion section enter a value in the increment field and
press either of the
buttons. Be sure that the value is within the confines of
the travel limits. The stage should move and you should see the Calc and Enc fields
change and end at the same value.

Frequently Asked Questions
Why is my stage continuously running in one direction when set to closed loop (nFBK2, nFBK3)?
Most likely your encoder polarity is backwards. Use the nEPL? command to query the current
setting and then if it is 1 send nEPL0 if it is 0 send nEPL1.
How do I get my settings like velocity, acceleration, and limits to remain when I power down the
controller?
Use the nSAV command. This command writes all current settings to non-volatile RAM which will
allow them to persist between power cycles. If you would like to revert to the factory settings
simply use the nDEF command to revert the controller to its default parameters. (Note: to have
these persist between power cycles don’t forget to run the nSAV command)
What do the red and green LEDs mean?
The top LED (labeled 2 to the right) is an
address indicator. At start up it will flash
from Red (unaddressed) to orange
(currently being addressed) to Green
(addressed and ready for commands).
The bottom LED is an error indicator.
When an error occurs, the LED (labeled 1
to the right) will illuminate red. Use the
nERR? command to read all errors. By
default this LED will be off.
