• Block functions
• Signal normalization
6.1.1 Variable Connection Methods
The source allows you to assign the signal for the input Block.
Thanks to a predefined list, Pick List, the user can select the signal origin
by connecting it to the input Block.
The signal selected will be assigned to the source. This signal controls the
Block Function and is therefore defined as a control signal. The signals
come from different points of the control system.
The connection points can derive from:
1 - Physical terminal board
analog and digital signals from the drive terminal strip and from the
EXP expansion cards.
2 - Analog and digital signals
from DGFC or APC option cards, Field Bus, keypad.
3 - Drive internal variables
using keypad or toolbox.
The control signal is always connected on the Source of each Block. The
state of this signal depends on the Block Function.
I.e.:
- the Ramp Setpoint Block which generates the ramp reference, defaults
D00.00 - Ramp ref 1 src source from the Analog input 1 output signal (the
Block output on the analog Input 1).
This signal is in the pick-list of the D00.00 - Ramp ref 1 src (Pick List 07),
and can be changed. I.e.: 000-DigRampRef 1 (Ramp setpoint block internal
value).
- the analog Input Block, connects on its C01.00 - AI 1 sgn src source
(which inverts the output reference signal) the 000-NULL signal.
If the user wants to enable the specific function, he has to make a selection
inside the pick-list of the C01.00 - AI 1 sgn src (Pick List 03). I.e.: 001-ONE,
002-DI 0 En mon, etc. .
