Input/output
Set
Analog input 1
as input for the load cell signal.
Analog input 1 / Select input 1= PID Feed-back
Set
Analog input 2
as line speed input (feed- forward).
Setting the feed-forward on analog input, seeing it is not directly inserted in the list of high-priority parameters,
it is necessary to pass through a supporting parameter
PAD 0.....PAD 15
.
Analog input 2 / Select input 2 = PAD 0
Set
Analog input 3
as input for the tension set (
PID offset 0
).
Analog input 3 / Select input 3 / PID offset 0
Set
Digital input 1
as enabling input of the PI block of the PID
Digital input 1 = Enable PI PID
Set
Digital input 2
as enabling input of the PD block of the PID
Digital input 2 = Enable PD PID
Parameters
Program
Speed base value
equal to the rated speed of the motor.
Speed base value
= 3000rpm
Program
PID source
as
PAD 0
.
(
PAD 0
has been used as supporting parameter of the feed-forward reading on
Analog input 2
)
For
PID source
set the parameter number to which it will be associated, choosing it from the list of paragraph
10.2. “
List of high-priority parameters
’ (
PAD 0
has the decimal number 503).
To obtain the correct value it must be added the decimal number 8192 (fixed offset):
PID source
= (8192 + 503) = 8695
Set
PID source Gain
so that
Feed-fwd PID
reaches, along with the max. analog value on
Analog input 2
, 85%
of its max. value = 10000 x 85%.
When an analog input is set on a PAD parameter , this will have a max. value +/- 2047.
So:
PID source Gain
= (max
Feed-fwd PID
x 85%) / max
PAD 0
= (10000 x 0.85) / 2047 = 4.153
Set
PID target
as
Speed ref 1
.
n
ote
:
When the ramp function is enabled,
Speed ref 1
is not available. In order to have it available,
it is necessary to set the parameter
Enable ramp
= Disable.
For
PID target
set the parameter number to which it will be associated, choosing it from the list of paragraph
10.2 “
List of high-priority parameters
’ (
Speed ref 1
has the decimal number 42).
To obtain the correct value it must be added the decimal number 8192 (fixed offset)
PID target
= 8192 + 42 = 8234
