Parameter settings for [K speed loop filter] (SFC), [Speed prop. gain] (SPG) and [Speed time integral] (SIt)
The following parameters can be accessed if [Motor control type] (Ctt) page 92 is set to [SVC V] (UUC),
[Sync. mot.] (SYn) or [Energy Sav.] (nLd).
General Case: Setting for [K speed loop filter] (SFC) = 0
The regulator is an "IP" type with filtering of the speed reference, for applications requiring flexibility and
stability (hoisting or high inertia, for example).
• [Speed prop. gain] (SPG) affects excessive speed.
• [Speed time integral] (SIt) affects the passband and response time.
WARNING
LOSS OF CONTROL
Bad parameter settings of the speed loop with High Inertia application may cause a Ramp non consistent
with application.
Failure to follow these instructions will result in death, serious injury, or equipment damage.
