RUN ENABLE
-6…7
Selects the source of the Run enable signal. See the figure on page
214
.
7 =
COMM
– Assigns the fieldbus Command Word as the source for the
Run enable signal.
• Bit 6 of Command Word 1 (parameter 0301) activates the Run
disable signal.
• See the fieldbus user’s manual for detailed instructions.
Note:
Hardware is bypassed if a command word is the source of the
Run enable signal.
1604

Selects the source for the fault reset signal. The signal resets the drive
after a fault trip if the cause of the fault no longer exists.
8 =
COMM
– Defines the fieldbus as a fault reset source.
• The Command Word is supplied through fieldbus communication.
• The bit 4 of Command Word 1 (parameter 0301) resets the drive.
