Summary
The checkbox
Synchronised
of the position set is used for the "flying saw" function. When
the
Flying saw
mode is active in the command window, the synchronisation can be
activated or deactivated by starting a position set. If the synchronisation is active, the
position of the encoder (master) that has been selected for the synchronisation is added to
the position setpoint. As a result, the drive follows the position changes of the master
drive.
If the master is not at a standstill when the positioning process is started, the resulting
offset will be compensated in a controlled manner. The speed of movement, which is used
for this purpose, corresponds to the speed of the master plus the speed of movement that
is specified in the position set. As far as the acceleration values are concerned, the values
stored in the position set that has been started will be used.
If the checkbox in the position set is not ticked, the synchronisation process will be
stopped when the positioning process starts. The positioning process begins with the
current actual speed, i.e. with the speed of the master. This results in a controlled
synchronisation deactivation.
The entire sequence can be automated rather well in the servo drive if the motion program
option (course program) is used. A superordinate control system can poll the output
Signal
1 position set active
to determine whether a synchronisation process is active or not.
