Dynamic drive model data
The drive is approximated as a PT2 low-pass filter 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.
p0345 can be set to specify the degree of damping to be applied when calculating the control
loop for "Calculate controller data".
Examples:
Damping 0.9
Slow control loop, which only has a low amount of overshoot
Damping 0.5
Fast control loop, which has a higher tendency to overshoot
