7.3 Description of Motion Axes

The motion axis is an internal counter of the servo drive. It is used for counting the absolute
position of the axis (32-bit integer). The following motion axes are included in this servo
drive:
Name of the Axis
1. Main Encoder
(P5-16)
2. Auxiliary
Encoder
(P5-17)
3. Pulse
Command
(P5-18)
4. Capture Axis
(P5-37)
5. Compare Axis
(P5-57)
6. Master Axis
(P5-86)
7. Command
Axis in PR
Mode
8. Internal Time

9. Synchronous
Capture Axis
(P5-77)
Note: Physical Axis: The position value is counted from the actual hardware signal.
Functional Axis: It is the virtual axis which has been processed by the physical. The
Virtual Axis: The axis position comes from the internal firmware of the servo drive. The

Description
It represents the absolute feedback position of the
motor. The unit is PUU (user unit).
It is counted by the pulse signal from CN5 and
usually connects to the second encoder or linear
scale. Its pulse is A/B TYPE.
It is counted by the pulse signal from CN1 and
usually connects to the pulse command of the
controller. The pulse type could be set by P1-00.
It is the axis which has CAP function. Its
command source could be the above mentioned
axis 1~3, which can write the new value into it and
has an offset from the physical axis. Moreover,
after capturing the first point, the axis position can
be redefined.
It is the axis which has CMP function. Its
command source could be the above mentioned
axis 1~4, which can write the new value into it and
has an offset from the physical axis.
It is the master axis of E-Cam. Its command
source could be the above mentioned axis 2, 3, 4
and 7, which can write the new value into it and
has an offset from the physical axis.
The command position is from the path generator
in PR mode.
It is the internal accumulative time counter of the
servo drive. The value increases 1 every 1ms.
It is similar to Capture Axis (P5-37); however, it
automatically adjusts the incremental pulse
between two CAPs to the setting value of P5-78.
value might not be the same as the source of physical axis. However,
the incremental value is the same as the one in physical axis.
