Connect to the speed reference 1 the PID output
Select Speed ref 1 src = PID out mon
Set Ramp out enable = Disable
Connect to the analog input 3 the tension reference.
Select PID draw src = An inp 3 output
Connect to the Digital input 1 the input enabling the PID PI Block
Select PID PI enab src = DI 1 monitor
Connect to the Digital input 2 the input enabling the PID PD Block
Select PID PD enab src = DI 2 monitor
In case just one contact is needed to enable the PI and PD section, it is possible to connect also PID PD enab src
on the digital input 1 as described below.
Select PID PD enab src = DI 1 monitor

1.16.6.3 Parameters

Set Full scale spd equal to the motor maximum speed.
Full scale spd = 3000 rpm
Connect
Mlt PI sel 0 = Null
Mlt PI sel 1 = One The selection of the PID Mlt PI sel 1 multiplier is therefore active.
Set
PID Mlt PI sel 1 = 1 The starting value is 1
Without any correction on the side of the regulator PI Block, the reference of the line speed (Feed-forward) has
to be multiplied by 1 and sent directly to the Drive speed regulator.
Set PI lim top and PI lim bot in order to obtain a maximum correction of the PI Block equal to 100% of the line speed.
The PI lim top and PI lim bot parameters can be considered, respectively, as a maximum and minimum multi-
plicative factor of the feed-forward.
PI lim top = 1
PI lim bot = 0
With this application the regulator carries out a proportional-integral control.
The gains of the different components have to be set, experimentally, with a loaded machine; such tests can be
started with the values below (default values):
Set PI P1 gain % = 4%
Set PI I1 gain % = 4%
Set PD P1 gain % = 1%
