Word 1..4: non usate
Word 5: Digital inputs from FIELDBUS
The virtual digital inputs from Fieldbus are specified in the low byte of the word:
bit [7..0]
MDI8
MDI7
MDI6
MDI5
MDI4
MDI3
(RESET)
MDI2
MDI1
The virtual auxiliary digital inputs from Fieldbus are specified in the high byte of the word:
bit 15
bit [14..8]
XMDI8/
Watchdog
XMDI7
XMDI6
XMDI5
XMDI4
XMDI3
XMDI2
XMDI1
The logical status of these bits becomes part of the overall state of the digital inputs of the drive (
M031
measure) along with other command sources, if at least one of the
C140
C142
parameters is set to
6:FieldBus.
NOTE
The auxiliary digitali put XMDI8, associated to bit 15 of Word 5, can only be
managed if:
R016
= 0 (watchdog not active), or
R016
> 0 (watchdog active) and
R018b
= 2.
WARNING
If
R016
> 0 (watchdog active), bit 15 can be managed according to parameter
R018b
:
R018b
= 0/1: see parameter description
R018b
= 2: the bit manages the XMDI8 input, and it does not depend on
watchdog management.
NOTE
Digital inputs MDI4 (external pre-charge closed signals) and MDI5 (filter
capacitor protection) are detected in the hardware drive terminal board only,
as they are affected by the hardware status of the cabinet where the drive is
installed.
