settings in parameter 8-50 Coasting Select to
parameter 8-56 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:
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 to default setting [1] FC RS485, 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
shows: Alarm 67, Option Changed.
When retrofitting a bus option into a
frequency converter that did not have a bus
option installed earlier, change the control to
bus-based. This change is required for safety
reasons to avoid an unintended change.
