Programming: Channel-specific activation (DRIVE)

Functionality
The axis-specific velocity limit, above which the reduced acceleration acts as an axis for
traversing movements, is activated with the command DRIVE.
Syntax
DRIVE
Meaning
DRIVE:
Supplementary conditions
Characteristic changeover
If the acceleration reduction is active due to the programming of DRIVE and the acceleration
profile is changed over by SOFT or BRISK, traversing is then done with a substitute
characteristic with reduced dynamic limit values.
With the re-programming of DRIVE, the reduction in acceleration can be re-activated beyond
the parameterized velocity limit.

Programming: Axis-specific activation (DRIVEA)

Functionality
The axis-specific velocity limit, above which the reduced acceleration acts as a single axis for
traversing movements, is activated for the programmed axes with the pre-defined
procedure DRIVEA().
