⇒ For machine data:
MD32910 $MA_DYN_MATCH_TIME[n] (dynamic response adaptation time constant)
the following values are achieved:
Axis 1: 0 ms
Axis 2: 10 ms
Axis 3: 6 ms
Approximation formulae
The equivalent time constant of the position control loop of an axis is calculated according to
the following formula:
• No feedforward control is active
0'326&75/B*$,1>V@

Note
If a geometry axis is subject to dynamic response adaptation, the same dynamic behavior is
also required of all other geometry axes and can be activated with the setting:
MD32900 $MA_DYN_MATCH_ENABLE= 1.
