(1)
A “0 = Not Stop” condition (logic 0) must first be present before a “1 = Start” condition will
start the drive. The Start command acts as a momentary Start command. A “1” will start the
drive, but returning to “0” will not
stop the drive.
(2)
This Start will not function if a digital input (parameters 361-366) is programmed for 2-Wire
Control (option 7, 8 or 9).
(3)
This Reference Select will not function if a digital input (parameters 361-366) is programmed
for “Speed Sel 1, 2 or 3” (option 15, 16 or 17). When using the Logic Command Word for the
speed reference selection, always set Bit 12, 13 or 14. Note that Reference Selection is
“Exclusive Ownership” see [Reference Owner]
on page 3-49.
