SIMOVERT MASTERDRIVES
By canceling the "Uncouple/Stop" command, it is possible to recouple a
stationary axis or axis operating with "Setpoint speed uncoupler" into a
synchronization system. The axis accelerates to the machine speed set
by the master via an acceleration ramp. The acceleration of this ramp
can be set at U628.2, and the rounding thereof at U627.2.
Once speed synchronization has been achieved, the binector B820
"Catch-up finished" goes to "1". This binector is usually controlled with
the "Synchronize to master value" input [841.2] in order to now create
accurate angular synchronization with the master.

You will find detailed information on the electronic cam (table
synchronization) in the "Synchronization functions" chapter of the
Function Description in manual /1/.
The cam [839] allows free assignment of master and slave positions.
This allows you to define the sequence of movements on the slave axis
with reference to the master.

Fig. 9-41 Example of a cam with 5 interpolation points
Linear interpolation is performed between the interpolation points, i.e. a
straight line is generated. Y1 is output for values less than X1
(horizontal movement to zero), Y5 is output for values greater than X5
(horizontal movement up to the table width).
