1.16.2.1 Machine Data

Rated speed of the Slave motor Vn = 3000rpm
Slave motor speed corresponding to the max. line speed = 85% Vn = 2550rpm
Maximum correction of the loading cell = +/- 20% of the line speed = +/- 510rpm
The drive of the Slave nip roll must receive the analog signals referring to the line speed, to the loading cell
(0....+10V) and to the tension (0....-10V), plus the digital commands referring to the PID control enabling.
The regulator output is sent to the speed 1 reference.

1.16.2.2 Input/Output

Drive settings: (only those referring to the PID function are described)
Connect to the analog input 1 the Dancer cursor.
Select PID fbk src = An inp 1 output
Connect to the analog input 2 the line speed reference (feed- forward).
Select PID inp FF src = An inp 2 output
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
Connect to the speed 1 reference the PID output
Select Speed ref 1 src = PID out mon
Set Ramp out enable = Disable

1.16.2.3 Parameters

Set Full scale spd equal to the motor speed corresponding to 100% of the line speed.
Full scale spd = 2550 rpm
Connect :
Mlt PI sel 0 = Null
Mlt PI sel 1 = One The selection of the PID Mlt PI sel 1 selector is therefore active
