33 Synchronous Control and Multiple-axis Synchronization Control
[ When synchronization is set to "1" and stopper method is set to "1" ]
synchronization at zero point establishment (#1493 ref_syn)
stopper method in zero point establishing operation (#1496 push_typ)
The zero points of both master and slave axes are determined by establishing the master axis's zero point.
Slave axis moves synchronously with master axis.
At zero point establishment of stopper method, push toward the machine end stopper until both master and slave
axes reach the current limit.
Also, the droop is canceled when the current limit is reached, which enables correction of the deviation to establish
the zero point. During automatic initialization, the above operation is performed by two pushing operations.
(a) Set "1" to "#0 Absolute posn set" of master axis.
When "1" to "#0 Absolute posn set" of slave axis is set, "setting error" occurs.
(b) As for marked point alignment method, align the master axis to the machine basic position (marked point)
and set "1" to "#1 Origin-P". The droop is canceled at this time.
As for stopper method, push toward the machine end stopper until both axes reach the current limit.
When the current limit is reached, the droop is canceled.
(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 the master
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 master axis. When "#2 Zero-P" is set to master axis, the same value is set to "#2 Zero-
P" of slave axis.
"#2 Zero-P" of slave axis cannot be set.
-
Synchronous error check is not performed during absolute position initial setting.
-
During automatic initialization, the values set to push speed (#2055 pushf) and approach distance (#2056
aproch) for master axis are also valid for the slave axis.
-
Set the same value to select zero point parameter and basic point(#2059 zerbas) for master and slave axes.
-
When different values are set to "#2 Zero-P" of master and slave axes, the automatic initial setting cannot be
started.
-
"1" can be set to "#0 Absolute posn set" with PLC signal (AZSn).
-
When "1" is set to "#0 Absolute posn set" in the following status, "setting error" occurs.
(*1) Synchronous control method is not selected.
(*2) Setting to "#0 Absolute posn set" of slave axis was attempted.
(*3) When the initial setting method is marked point alignment method I, "#2050 absdir" of the master and
slave axes is different.
The following is the operation example of stopper method when the slave axis reaches the stopper first:
Canceling the droop when the current limit is reached enables correcting the deviation of the master and slave axes
with the stopper as positive.
