Selecting the
Reference/Feedback
The PID Configuration menu includes
the
parameters
selecting
the
reference/feedback source.
You can set up to three sources, which
are summed up to each other.

Reference/Feedback
Sources
Sources:
REF

AIN1 Analog Input
AIN2
AIN2 Analog Input
Pulse Input

Sources :
Serial Link
Reference from serial link
Fieldbus
Reference from fieldbus
Keypad

Feedback reference only :
Iout
Output current
Vout
Output voltage
Vdc
DC bus voltage
Pout
Output power
The reference scaling is obtained through
the parameters included in the Reference
menu. Each source is assigned to a
parameter setting its min. value and max.
value
for
the
min./max.

See the PID Parameters menu.
Reference
P245 Min., P246 Max.
Feedback
P247 Min., P248 Max.
No reference scaling is required. References
are expressed as a percentage. As a
feedback reference, output current (Iout),
output voltage (Vout), DC bus voltage (Vdc)
are available, which refer (as full-scale values)
to the following:
Rated current of the selected motor (Mot.1
C018)
Rated voltage of the selected motor (Mot.1
