- 912 -
Function In synchronous control In composite control
Program restart Not possible with a program
containing synchronous
control.
Not possible with a program
containing composite control.
Cs contour control Synchronous control possible
(5).
Composite control possible
(5).
Spindle positioning Synchronous control does not
possible
Composite control does not
possible
EGB function Synchronous control does not
possible
Composite control does not
possible
Servo off Synchronous control does not
possible
Possible unless the
interchanging axis in
composite control is in the
servo off state.
(1) Processed after synchronous pulses are transferred to the slave.
(2) Processed on the master, then transfers synchronous pulses.
(3) Transfers composite control pulses and the acceleration/
deceleration type. As the time constant, uses that on the slave.
(4) Processed on the master, then transfers composite control pulses.
(5) Limited to combinations of Cs axes.
- Reading of coordinates in synchronous or composite control
In synchronous or composite control, the reading of custom macro
system variable positional information or of current coordinates from
the PMC window is as follows:
Positional information
type
In synchronous control In composite control
Absolute coordinate Reading possible. Reading possible.
Machine coordinate Reading possible. Reading possible.
End point of each block Reading possible on the master
only.
Reading possible.
Skip signal position Reading possible on the master
only.
Reading not possible.
- Canceling synchronous or composite control
Synchronous or composite control is canceled in the event of the
following, as well as when the synchronous/composite control axis
selection signal becomes "0".
(1) Emergency stop
(2) Reset
(3) Servo alarm
(4) Servo off *1
(5) Overtravel
(6) Alarm related to synchronous or composite control
(7) Alarm PW0000
If one of the above events occurs in either path, all paths will be
released from synchronous or composite control. If one of the above
events occurs in either path in synchronous or composite control, the
other path will automatically be placed in feedhold state (during
automatic operation) or in interlock state (during manual operation).
