Activation
The values for the adaptation are entered in MD 32910 DYN_MATCH_TIME [n], usually for
the axis. The adaptation is only possible if MD 32900 DYN_MATCH_ENABLE =1 has bee set
for the axis/spindle.
With active function G331/G332, parameter block n (0...5) of the axis of MD 32910 becomes
automatically active, which acts corresponding to the gear stage for the spindle. The gear
stage is dependent on the spindle speed with M40 or is directly set by M41...M45 (see also
Section 4.5.3 Start–up of the spindle).

32900 Dynamic response adaptation 0
32910 Time constant of dynamic adaption (control parameter set no): 0...5 0.0
Determination of value
The dynamic value of the spindle is stored for each individual stage in MD 32200
POSCTRL_GAIN[n] as closed–loop gain. An adaptation of the axis to these values must be
made in MD 32910 DYN_MATCH_TIME [n] in accordance with the following instruction:
1 1
MD 32910 DYN_MATCH_TIME [n] = –––––––– – –––

The entry to be made in MD 32910 requires the time unit s. The values of MD 32200
POSCTRL_GAIN[n] for spindle and axis must be converted accordingly:
1000

[n]

When using further gear stages with G331/G332, the adaptation must also be carried out in
these parameter blocks.
