Parameter descriptions
478 Actual Percentage Source, PID real value input
The analog input or the repetition frequency input to which the PID real value is applied can be se-
lected via parameter
Actual Percentage Source 478. The actual value can also be transmitted via a
bus system.
Actual Percentage Source 478

Analog Input MFI1A
Analog signal at multifunction input 1 (terminal X12.3). Factory
setting. Via parameter Operation mode MFI1 452, the input
must be set up as an analog input (voltage or current). See
chapter 7.6.1 "Multifunction input MFI1".
2 -
Analog Input MFI2A
Analog signal at multifunction input 2 (terminal X12.4). Via pa-
rameter Operation mode MFI2 562, the input must be set up
as an analog input (voltage or current). See chapter
7.6.2
"Multifunction input MFI2".
