Denominator equivalent time constant for feedforward control of acceleration (P-AXIS-00226)

P-AXIS-00226

Denominator equivalent time constant for feedforward control of acceleration

Description

The acceleration command variable is weighted with the mechanical time constant 'vorsteuer.vs_a_faktor/vorsteuer.vs_a_nenner' of the drive.

The drive is modelled here as a first-order time delay element (see in [AXIS]).

In the Laplace-range the following transfer function is obtained

Gantrieb = 1 / [ 1 + Ta * s ] where Ta = vs_a_faktor / vs_a_nenner

Parameter

vorsteuer.vs_a_nenner

Data type

SGN32

Data range

0 ≤ vs_a_nenner ≤ MAX(SGN32)
