Selecting the
Ref/Feedback Sources
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.
Forcing the
Reference/Feedback
Sources
Sources:
REF Ref Analog Input
AIN1 AIN1 Analog Input
AIN2 AIN2 Analog Input
Pulse Input Frequency Input (MDI8)
Encoder Encoder Input
Sources:
Serial Link Reference from serial link
Fieldbus Reference from fieldbus
Keypad Ref. from display/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.
PID Reference/Feedback value.
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 C019)
DCb Bus 1500 V.
