Axis Configuration
Figure C-5
The Configure/Axis Configuration Window
Motor
Servo
or
Stepper
This selection is used to enable/disable the step pulse output for a given pair of axes. Selecting
“step” will enable the step output for the pair of axes (0 and 1, 2 and 3, etc.). The analog output
is available regardless of the selection. When the motor type is changed, a set of default tuning
parameters will be loaded into SETUP for that axis.
Encoder
Open-loop
or
Closed-loop
This selection enables you to indicate if a pair of axes is to be open-loop or closed-loop.
If closed-loop is selected, the controller will use feedback from an external device to close the
loop.
If open-loop are selected (and
Step
was selected on
Motor
line), the board will direct the step
output back into the encoder input for the axis, in effect digitally closing the loop on the con-
troller
