Function:
The setting in this parameter overrides
the settings in O-50 Coasting Select to
O-56 Preset Reference Select.
Control by using both digital input and
control word.
Control by using digital inputs only.
Control by using control word only.
Function:
NOTE
This parameter cannot be adjusted while
the motor is running.
Select the source of the control word: one of
two serial interfaces or four installed options.
During initial power-up, the frequency converter
automatically sets this parameter to [3] Option A
if it detects a valid fieldbus option module
installed in slot A. If the option is removed, the
frequency converter detects a change in the
configuration, sets O-02 Control Word Source
back to default setting RS-485, and the
frequency converter trips. If an option is
installed after initial power-up, the setting of
O-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 done
for safety reasons to avoid an accidental
change.
O-03 Control Word Timeout Time
Range: Function:
1 s [0.1 - Enter the maximum time expected to pass
*
18000 s] between the reception of two consecutive
messages. If this time is exceeded, it indicates
that the serial communication has stopped.
The function selected in O-04 Control Word
Timeout Functionis then carried out. A valid
control word triggers the time-out counter.
O-04 Control Word Timeout Function
Select the time-out function. The time-out function activates
when the control word fails to be updated within the time
period specified in O-03 Control Word Timeout Time.
Option: Function:
[0] Off Resumes control via serial bus (fieldbus or
*
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
time-out. If communication resumes after a
time-out, O-05 End-of-Timeout Function
defines whether to resume the set-up used
before the time-out, or to retain the set-up
endorsed by the time-out function.
