PID target
Address of the parameter which contains the value to be used as PID target. To obtain
the real settable value, it is necessary to add +2000H (8192 decimal) to the parameter
number.
PID out scale
Matching factor of
PID output
. Its value depends on the parameter to which the regula
-
tor output is addressed.
Through the parameter
PID target
it is possible to select which point of the drive will be addressed for output
signal of the regulation. The selectable parameters are those assigned as writing parameters (W or R/W) indi
-
cated in the paraghraph 10.2. “
List of high-priority parameters
’”. The units are those indicated in the notes at
the end of the paragraph.
Programming example of the speed reference 1 (parameter
Speed ref 1
) on
PID target
:
Menu OPTION
————> PID
————> PID target
————> PID target = 8234
PID target
must be set according to the number of the parameter to which it will be associated, choosing it from
the paragraph 10.2. “List of high-priority parameters’” (
Speed ref 1
has the decimal number 42). To obtain the
value it must be added the decimal number 8192 (fixed offset):
8192 + 42 = 8234.

When the ramp function has been enabled, Speed ref 1 will be automatically programmed
on its output. To have it available it is necessary to set parameter Enable ramp = disable.
Speed ref 1
will be set in RPM x 4, considering that
PID output
assumes values included between 0....10000,
it is necessary to set appropriately the calibration through
PID out scale
.
Calculation of
PID out scale
:
If it is necessary that
PID output
, at its max. value = 10000, corresponds at speed reference = 2000rpm it is
necessary to set:
PID out scale
= (2000 x 4) / 10000 = 0.8
It is possible to read the set value of
Speed ref 1
in the appropriate parameter of the menu
INPUT VARIABLES
/ Speed ref
.
n
ote
:
The value of PID out scale will be defined according to the system which is being controlled.
For a better understanding, please refer to the paragraph “Application examples”.
