7.2 Programming
7.2.1 Menu display modes
The programming menu can be displayed in two modes, which can be selected
using the Access mode parameter (04 - DRIVE CONFIG menu), see chapter
6.5.2:
• Easy (default) only the main parameters are displayed.
• Expert all the parameters are displayed.
7.2.2 Programming of “function block” analog and digital input signals
The signals, variables and parameters of each single “function block” of the drive
are interconnected in order to achieve the congurations and controls inside the
control system.
These can be managed and modied using the keypad, PC congurator or eld-
bus programming.
The programming mode is based on the following logic:
src (source; i.e.: DC voltage ref src, PAR: 608)
This term denes the source of the function block input, i.e. the
signal to be processed in the function block.
The different congurations are dened in the relative selection lists.
mon (display; i.e.: Analog input 1 mon PAR: 1500)
This term refers to the variable output from the function block,
which is the result of the calculations performed on the actual
block.

7.2.3 Variable interconnections mode
The source (src) allows the desired control signal to be assigned to the function
block input.
This operation is performed by using specic selection lists.
Possible control signal sources:
1 – Physical terminal
The analog and digital signals come from the terminal strip of the regulation card
and/or from those of the expansion cards.
2 – Drive internal variables
Internal drive control system variables, from “function block” calculations, sent via
keypad, PC congurator or eldbus.
