- 925 -
Synchronous or composite control cannot be started, either,
if the axis on which synchronous or composite control is to
start is either of the following states:
- Servo off
- Overtravel
2. An attempt to raise a synchronous or composite start signal
results in an alarm.
(1) An attempt is made to use an axis already under
synchronous or composite control for another synchronous
or composite signal operation. (Alarms (PS0352, PS0357))
-> You cannot use a single axis for a combination of
multiple synchronous or composite control operations.
Note, however, that the synchronous master axis can
be the master of multiple synchronous slave axes at the
same time. You can add additional slave axes while
synchronous control is in progress.
(2) The axis number set in a parameter is greater than the
number of controllable axes. (Alarms (PS0350, PS0355))
-> The number of the synchronous master axis and that of
the interchanging axis subject to composite control
must not exceed the number of axes controllable in the
remote path (or the local path if you are to perform
synchronous control in that path).
(3) The tool is moving along the axis that you want to control.
(Alarms (PS0351, PS0356))
→ At the start of synchronous or composite control, the tool
must be stopped on the axis subject to that control. That
the tool is stopped on an axis means that the speed
specified after acceleration/deceleration is zero.
(4) An axis on which you want to perform synchronous or
composite control belongs to another machine group.
(Alarms (PS0350, PS0355))
-> The axes on which you want to perform synchronous
or composite control must be of the same machine
group.
3. An attempt to cancel synchronous or composite control results in
alarms (PS0351, PS0356).
(1) The tool is moving along the axis on which the control you
want to cancel.
-> To cancel synchronous or composite control, the tool
must bet stopped on the axis on which to cancel it.
That the tool is stopped on an axis means that the
speed specified after acceleration/deceleration is zero.
Before canceling, make sure that the movement in
progress signal Fn102 has changed to "0".
