6.1 8-** PROFIBUS Parameters
8-01 Control Site
Option: Function:
The setting in this parameter overrides the
settings in
parameter 8-50 Coasting Select to
parameter 8-56 Preset Reference Select .
[0] Digital and
ctrl.word
Control by using both digital input and
control word.
[1] Digital only Control by using digital inputs only.
[2] Controlword
only
Control by using control word only.
8-02 Control Word Source
Option: Function:
NOTICE
This parameter cannot be adjusted
while the motor is running.
Select the source of the control word: 1 of 2
serial interfaces or 4 installed options. During
initial power-up, the frequency converter
automatically sets this parameter to
[3] Option
A , if it detects a valid fieldbus option installed
in slot A. When the option is removed, the
frequency converter detects a configuration
change, sets
parameter 8-02 Control Word
Source back to default setting RS-485, and
trips. If an option is installed after initial
power-up, the setting of
parameter 8-02 Control Word Source does not
change, but the frequency converter trips and
displays: Alarm 67
Option Changed .
When retrofitting a bus option into a
frequency converter that did not have a bus
option installed to begin with, take an active
decision to move the control to bus-based.
This is required for safety reasons to avoid an
accidental change.

8-03 Control Word Timeout Time
Range: Function:
1 s
*
[ 0.1 -
18000 s] Enter the maximum time expected to pass
between the reception of two consecutive
telegrams. If this time is exceeded, it indicates
that the telegram communication has stopped.
The function selected in
parameter 8-04 Control
Word Timeout Function is then carried out. A
valid control word triggers the time-out counter.
8-04 Control Word Timeout Function
Select the timeout function. The timeout function activates when
the control word fails to be updated within the time period
specified in
parameter 8-03 Control Word Timeout Time .
Option: Function:

standard) using the most recent control
word.
[1] Freeze output Freezes output frequency until communi-
cation resumes.
[2] Stop Stops with auto restart when communi-
cation resumes.
[3] Jogging Runs the motor at jog frequency until
communication resumes.
[4] Max. speed Runs the motor at maximum frequency until
communication resumes.
[5] Stop and trip Stops the motor, then resets the frequency
converter to restart: Via the fieldbus, via
[Reset], or via a digital input.
[7] Select setup 1 Changes the set-up upon reestablishment of
communication following a control word
timeout. If communication resumes after a
timeout,
parameter 8-05 End-of-Timeout
Function defines whether to resume the set-
up used before the timeout, or to retain the
set-up endorsed by the timeout function.
