Example: absolute synchronization in running operation
•
When the operating mode is activated, the master axis moves at
constant velocity.
•
The synchronization status signals "synchronization running"
(P-0-0152, bit 0 = 0).
•
Based on its current position the slave axis accelerates to the
synchronous velocity. While doing this the synchronization
acceleration (P-0-0142) is effective.
•
After velocity adjustment the absolute position reference is
established. Position adjustment takes place with parameterized
synchronization acceleration (P-0-0142) and synchronization velocity
(P-0-0143).
•
As soon as the position difference between master axis and slave axis
is smaller than the "position synchronization window" (S-0-0228), the
status bit "slave axis has been synchronized" (P-0-0089, bit 8 = 1) is
output.
Bit 0 is set in parameter P-0-0152 when synchronization has been
completed.
