Detailed description
2.6 Dynamic response of following axis
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.
Caution
This option can only be used in conjunction with servo trace and with the appropriate
technical knowledge of the control.

POWER ON
During POWER ON the values of VELOLIMA and ACCLIMA are initialized to 100%.
Mode change
The dynamic offsets remain valid only on transition from AUTO → JOG mode.
RESET
The validities of the (VELOLIMA and ACCLIMA) dynamic offsets after RESET depend on the
setting in the channel-specific machine data:
MD22410 $MC_F_VALUES_ACTIVE_AFTER_RESET (F Function is active even after
RESET)
Value
0
1
This response also applies for dynamics offsets set using static synchronized actions. If this
is not the case even when MD22410 = 0, then the IDS synchronized action should trigger a
repeat or continuous writing of the dynamic offset.

Description
The values of VELOLIMA[FA] and ACCLIMA[FA] are set to 100% after RESET.
The last programmed values of VELOLIMA[FA] and ACCLIMA[FA] are also active after
RESET.
