thebasic setupfor bothtypes ofaxis . Commands typed in the Command window have
immediateeffect -they do not need to be separ ately downloaded to the NextMove PCI.

5.3.1 Choosing an axis - 1, 2, 3 and 4 axis cards

Forthe 1, 2, 3 and 4 ax is cards, each axis can be configured as eithera ser vo axis or a
stepperax is. The factory preset configuration for all the axes iss ervo. If a stepper axis is
requiredit mus t be configured:

immediately sets axis 0 to be a stepper
axis.
Note: ForNext Move PCI products, axis numbering always begin at 0. For example, a
fouraxis card has axes numbered 0, 1, 2 and 3.
Whenan axis isc onfigured as a stepper axis, it uses the corres pondingly numbered stepper
outputchannel. F or example, axis 0 will use stepper channel 0 as its output (breakout module
connector X10, pins 1, 2, 6 and 7). See section 4.5.5 for details of the stepper channel
outputs.

5.3.2 Choosing an axis - 8 axis card
