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). Note that Reference Selection is “Exclusive
Ownership” see [Reference Owner]
on page 3-52.
