ENCODER
The Encoder source is an encoder input: it can come from the terminal board (terminals MDI6, MDI7) in Encoder
A, or from the optional Encoder B board (see the ENCODER/FREQUENCY INPUTS MENU). It generates a
reference resulting from the correct setting of the relevant parameters (P073, P074), allowing the relevant scaling
(see the INPUTS FOR REFERENCES MENU).
UP/DOWN from digital inputs
To enable the UP/DOWN from digital inputs also set the relevant Up and Down inputs (see the DIGITAL INPUTS
MENU).
XAIN4 and XAIN5
XAIN4 and XAIN5 come from the analog inputs in the terminal board of ES847 and generate a reference determined by
the settings of the relevant parameters (P390 to P399), allowing proper scaling, offset compensation and filtering (see
the INPUTS FOR REFERENCES FROM OPTIONAL BOARD ).
Figure 50: Selecting the source references
36.1.3. ALTERNATIVE COMMAND AND REFERENCE SOURCES
A digital input can be set as a selector between 2 alternative command and reference sources.
Example:
C179 MDI To select sources = MDI6
C140 To select command source number 1 = Keypad
C141 To select command source number 2 = Fieldbus
C143 To select reference source number 1 = AIN1
C144 To select reference source number 2 = Fieldbus
If MD16 (in the drive terminal board) set as a selector is open, the drive will consider number 1 as reference and
command sources (that is C140 = Keypad and C143 = AIN1); if it is closed, number 2 will be considered (C141 =
Fieldbus and C144 = Fieldbus). See also How to Manage the Reference Sources.
If references sources 3 and 4 (C145 and C146) are not set to Disable, the reference sent for these sources shall be a
sum of the source selected by MD16 vector.
Please refer to C179 in the DIGITAL INPUTS MENU.
