Programming (VELOLIMA, ACCLIMA)

Reducing or increasing dynamics limits
The dynamic limits of the following axis (FA) specified through MD32000 and MD32300 can
be reduced or increased from the part program:
Command
VELOLIMA[FA]
ACCLIMA[FA]
The values specified during the programming of VELOLIMA[FA] and ACCLIMA[FA]are
process values. They define the proportion with which the parameterized dynamic limits
(MD32000 and MD32300) are to be considered:
Range of values
1 ≤ value < 100
100 ≤ value < 200
The dynamic limits for the velocity and acceleration of the following axis are then calculated
as follows:
Maximum axis velocity = MD32000 $MA_MAX_AX_VELO * VELOLIMA[FA]
Maximum axis acceleration = MD32300 $MA_MAX_AX_ACCEL * ACCLIMA[FA]
Note
The reduction / increase is effected on the overall dynamics of the axis, i.e., on the sum of the
axis component from overlay and coupling.
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
446
Meaning
Reducing or increasing the maximum Axis velocity
Reducing or increasing the maximum Axis acceleration
Meaning
effects a Reduction in the dynamic limit
effects an increase in the dynamic limit
