Synchronisation to velocity
In Synchronisation to velocity [
}
11] the slave axis is synchronised to the master axis using the specified
dynamic parameters as rapidly as possible. In the synchronous phase, the slave velocity is proportional to
the master velocity, so that:
The synchronisation procedure
Synchronisation of the slave axis to the master axis proceeds according to the following scheme:
1. Starting the Universal Flying Saw. This corresponds to the logical coupling to the master axis. This
moment is referred to as the coupling time.
2. The synchronisation phase: The slave is accelerated from its initial condition up to the velocity of the
master whilst observing the boundary conditions for slave movement specified by the user. The time
at which the synchronisation phase changes to the synchronous phase is referred to as the synchroni-
sation time.
3. Synchronous phase: The slave moves synchronously with the master.
4. Uncoupling the Universal Flying Saw. This is an online change. The coupled slave once again be-
comes an independent master that continues to move without limit with the velocity resulting from the
online change.
5. This could mean that the former slave restarts or stops. The full functionality of a TwinCAT NC master
axis is once more available.
Synchronisation to position
In Synchronisation to position [
}
15] the slave axis is synchronised to the master at the specified
synchronisation position using the specified dynamic parameters. This means that the slave axis reaches the
synchronous velocity at exactly the synchronisation position of master and slave, after which it moves in
synchronism with the master. The slave velocity in the synchronous phase is governed by:
The synchronisation procedure
Synchronisation of the slave axis to the master axis proceeds according to the following scheme:
1. The start of the Universal Flying Saw. This is the logical coupling to the master axis. This moment is
referred to as the coupling time.
2. The synchronisation phase: The slave is accelerated from its initial condition to the master's velocity,
reaching the slave synchronisation position and synchronisation velocity precisely at the specified
master synchronisation position. The boundary conditions specified by the user for slave movement
are maintained during this process. The time at which the synchronisation phase changes to the syn-
chronous phase is referred to as the synchronisation time.
3. Synchronous phase: The slave moves synchronously with the master.
4. Uncoupling the Universal Flying Saw. This is an online change. The coupled slave once again be-
comes an independent master that continues to move without limit with the velocity resulting from the
online change.
5. This could mean that the former slave restarts or stops. The full functionality of a TwinCAT NC master
axis is once more available.
