# 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 by the mechanical time constant of the drive. The drive is modelled here as a first-order time delay element (see figure of the conventional feedforward control]). In the Laplace range the following transfer function is obtained

with

P-AXIS-00225: time constant numerator.
