11.28 Compensation of moment of inertia (dv/dt injection)
(see also Section 8, Sheet G153)
P540
FDS
Acceleration time
The acceleration time is the time that would be needed to accelerate the
drive from 0% to 100% of maximum speed (with no friction) at 100%
converter rated DC current (armature) and 100% rated motor field current
(i.e. 100% flux). It is a measure of the moment of inertia on the motor shaft.
This parameter is set automatically during the optimization run for friction
and moment of inertia compensation (P051=28).

Time difference for dy/dt of ramp-function generator
Ramp-function generator:
Setting of dt for the output of dy/dt at a connector, i.e. at K0191, the change
in the output quantity of the ramp-function generator (K0190) is output
within the period set in P542
Example:The ramp-function generator is currently ramping up with a ramp-
up time of P311=5s, i.e. a ramp-up operation from y=0% to
y=100% takes 5s.
- A time difference dt of P542=2s is set.
- ⇒ A dy/dt of 40% appears at connector K0191 since the dy
within
the set dt of 2 s equals (2s/5s)*100%..

Threshold for SAD-dependent acceleration
With respect to the SAD-dependent acceleration function, only the
component of the speed controller setpoint/actual value difference which
has an absolute value in excess of the threshold set in this parameter is
switched through (see also parameter P541).
