The drive is approximated as a PT2 low pass for the purpose of dimensioning
the closed-loop velocity control. The characteristic values “natural frequency”
and “damping” are calculated and preset from other drive data by the “Calculate
drive model data” function.
With MD 5180: CLOSED_LOOP_SYSTEM_DAMPING can be set to specify the
degree of damping to be applied in calculating the control loop during “Calculate
controller data”.
Example: Damping of 0.9
Slow closed-loop system with infrequent overshoots
Damping of 0.5
Fast closed-loop system with frequent overshoots
Dynamic drive
