Axis Parameter Area Section 4-4
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.
Specified Unused Axes (Word m+2 Bits 12 to 15; Supported for Unit
Version 2.3 or Later)
This parameter is used to specify unused axes. Parameter wiring (e.g., CW,
CCW, and emergency stop) is not required for the specified unused axes.
Example 1
The PCU will operate according to the axis parameters saved in the PCU’s
flash memory.
Example 2
Operation for the X and Z axes will be performed according to the axis param-
eters 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.
4-4 Axis Parameter Area
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.
4-4-1 Outline
The axis parameter settings used will be selected from the following, accord-
ing 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
common 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
common 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
operating commands.
