Axis 1:
MD32910 $MA_DYN_MATCH_TIME = 0 ms
Axis 2:
MD32910 $MA_DYN_MATCH_TIME = 30 ms - 20 ms = 10 ms
Axis 3:
MD32910 $MA_DYN_MATCH_TIME = 30 ms - 24 ms = 6 ms
Approximation formulas for the equivalent time constant of the position control loop of an axis
The equivalent time constant T
on the type of precontrol:
Without precontrol:
With speed precontrol:
For combined torque/speed precontrol
Note
If dynamic response adaptation is realized for a geometry axis, then all other geometry axes
must be set to the same dynamic response.

Parameter sets of the position controller

Six different parameters sets
The position control can operate with 6 different servo parameter sets.
They are used as follows
1. Fast adaptation of the position control to altered machine characteristics during operation, e.g. a gear change
of the spindle.
2. Matching the dynamics of an axis to another axis, e.g. during tapping.
