M3: Coupled axes
5.6 Dynamic response of following axis
Programming in synchronized actions
The possibility of programming VELOLIMA[FA] and ACCLIMA[FA]in synchronized actions
depends on the coupling type:.
Coupling type
Tangential correction
Coupled motion
Master value coupling
Electronic gearbox
Synchronous spindle
Generic coupling
Synchronization between following and leading axes
The acceleration characteristics set and the dynamics offsets set change the duration for
synchronization between following and leading axes during acceleration operations as
follows:
Dynamic offset
Dynamic reduction
Dynamic increase
Note
The user must restore the technological synchronization between machining and the
synchronism difference.
Acceleration mode
Only BRISKAis available for the following axis, i.e., abrupt axis acceleration. Acceleration
modes SOFTA and DRIVEAare not available for the following axes described.
Furthermore, it is also possible to configure the positions controller as a PI controller.
This option can only be used in conjunction with servo trace and with the appropriate
technical knowledge of the control.

Activation
Prolongs the synchronized difference.
The monitoring from leading to following value may exceed the
allowed range for extended periods.
Shortens the synchronized difference.
The monitoring of leading and following values may exceed the
allowed range for short periods.
