Axis Names
Defines the axis letters referenced in the motion program. Replace the default values with the
desired letter name for each axis using the following conversions.
65 = A 85 = U 88 = X
66 = B 86 = V 89 = Y
67 = C 87 = W 90 = Z
1020 AXIS NAME 1 88

Reference Position Return Not Required
Set ZRN for each axis. This prevents an alarm when a command is generated in automatic
operation before a reference is performed.

Inch or Metric Feedback
You don’t need to set this parameter to remove any alarms, but we will be referring to
something called the least command increment (LCI) later in the chapter. This is the smallest
axis movement the machine can command and this parameter tells the control what
measurement system to use. If you have a metric system machine, leave INM at zero. If you
have an inch machine, set INM to one.
1001 INM
00000000
This next parameter sets the actual value of the LCI. The common setting used in most
applications is 0.001mm or 0.0001 inches, depending on the measurement system you are
using. Leave ISC and ISA set to zero to use this standard setting for your least command
increment.
