ARTDrive V2 series - Instruction Manual
Chapter 7 Appendix • 331
7.5.2.1 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.
7.5.2.2 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 sr
c =
An inp 2 output
Connect to the analog input 3 the tension reference.
Select
PID draw sr
c =
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
7.5.2.3 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
Set:
PID Mlt PI sel 1
= 1
The starting value is 1
Without a correction performed by the regulator PI Block, the line speed
reference (Feed-Forward) must be multiplied by 1 and must be sent directly
to the Drive speed regulator. The regulator usually carries out a Proportional-
Integral control. The correction is stated as a percentage of the line speed,
