Axis Parameter Area

4-3 Axis Parameter Area

4-3-1 Outline

The meanings of the individual axis settings are as follows:
0: The axis parameter settings in the DM Area words allocated to Special I/O
Units will be used.
1: The default axis parameter settings will be used. The settings in the DM
Area words allocated to Special I/O Units will not be used.
If the PCU's flash memory (00) is designated as the location of the axis parame-
ters in the parameter designation setting, the above settings will not be used.
When using a 1-axis or 2-axis PCU, set 0 for the other axes (i.e., those not con-
trolled by the PCU). Setting to a value other than 0 will result in a parameter des-
ignation error (error code 0013).
Note The settings in the DM Area words allocated to Special I/O Units will not be used
for any axes that are set to 1. This means that when control is not required for all
axes (e.g., when a 4-axis PCU is used to control 3 axes), if uncontrolled axes are
set to 1, there is no need to make settings for those axes in the DM Area.
Example 1
The PCU will operate according to the axis parameters saved in the PCU's flash
memory.
Example 2
m+2
Operation for the X and Z axes will be performed according to the axis parame-
ters set in the following DM Area words allocated to Special I/O Units.
X-axis parameter area: words m+4 to m+31
Z-axis parameter area: words m+60 to m+87
The default settings will be used for the Y and U axes.
The axis parameters are used for settings that include the pulse output type,
input signal logic, and operation modes for axes subject to PCU control.
The axis parameter settings used will be selected from the following, according
to the common parameter settings.
• The axis parameters saved in the PCU's non-volatile (flash) memory
(when 00 is set for the parameter designation (word m+2, bits 00 to 07) in the
common parameters)
• The axis parameters set in the DM Area words allocated to Special I/O Units
(for axes for which the axis specification (word m+2, bits 08 to 11) is set to 0
when 01 is set for the parameter designation (m+2, bits 00 to 07) in the com-
mon parameters)
• The default axis parameters
(for axes for which the axis specification (word m+2, bits 08 to 11) is set to 1
when 01 is set for the parameter designation (m+2, bits 00 to 07) in the com-
mon parameters)
The axis parameters are read into the PCU's internal memory at power up or
restart. Also, by using data transfer, changes in the axis parameters other than
the I/O settings and the operation mode can be reflected in subsequent operat-
ing commands.
When the axis parameters are set from the DM Area words allocated to Special
I/O Units, the setting area (i.e., the axis parameter area) will follow on from the
