33 Synchronous Control and Multiple-axis Synchronization Control
Position alignment at machine setup
In machine setup, carry out the position alignment of the synchronous axes in the following procedure.
(1) Select the correction mode, and feed the master and slave axes using the manual handle to correct the error
between the two axes.
Use an instrument such as a level to detect horizontal level errors between the synchronous axes.
(2) Change back to synchronous mode, and carry out the zero point initial setting.
There are two types of zero point initial setting: stopper method and marked point alignment method.
Moreover, there are two types of stopper methods: manual initialization and automatic initialization, and there are
two types of marked point alignment methods: Marked point alignment method I and marked point alignment
method II.
When automatic initialization is selected, some part of the following operations are automated.
[ When synchronization is set to "0" ]
synchronization at zero point establishment (#1493 ref_syn)
Master axis and slave axis determine their zero points individually.
(a) Set "1" to "#0 Absolute posn set" of master and slave axes individually.
(b) As for marked point alignment method, align both axes to the machine basic position (marked point) and
set "1" to "#1 Origin-P".
As for stopper method, push toward the machine end stopper until both axes reach the current limit.
(c)
As for stopper method and marked point alignment method I, if the axis is moved in the opposite direction
as final advance direction or basic Z direction with "Ret. Ref. P." in "State" item and reached to each axis'
grid point, the absolute position is established.
As for marked point alignment method II, the absolute position is established without moving to the grid
point.
(d) Set "#2 Zero-P" to each axis.
-
Synchronous error check is not performed during absolute position initial setting.
-
When initial setting is carried out for one of the two synchronous axes, do this in asynchronous mode.
-
During automatic initialization, the values set to push speed (#2055 pushf) for master and slave axes are valid
respectively.
-
"1" can be set to "#0 Absolute posn set" with PLC signal (AZSn).
The following is the operation example when synchronization at zero point establishment (#1493 ref_syn) is set to
"0" in zero point establishing operation:
Master axis
Basic machine
coordinate zero point
Slave axis
(Note)
In carrying out zero point initial setting, even when one axis has stopped on a grid, the other axis keeps
traveling. Thus, decelerate enough before setting.
