Application Notes C-19
❏ Enter the step value in Par 60 [TstGen Amplitude], so that the speed
remains inside the range to be tuned.
❏ The optimization is carried out separately for each range and the
parameters of the regulator are set for each range with Pars
[Adaptive P Gainx] and [Adaptive I Gainx].
❏ After the optimization of the different phases review the entire
speed range. By changing the value of [Adaptive Joint x] it is
possible to reduce the instabilities present in the transients during
the changes from one range to the other. Increasing the values
transients are slighter.
• When Par 182 [Adaptive Reg Typ] = 1 “Adaptive Ref”, tuning is
application specific.
• When the speed zero logic (see page C-22
) is disabled (factory default
setting) and the drive is disabled, the gains of the speed regulator are
active. These are set via Pars 188 [Adaptive P Gain1] and 189 [Adaptive
I Gain1]. When the speed zero logic is enabled, the values set when the
motor is stopped are valid.
