(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). Note that Reference Select is “Exclusive Ownership” - see drive User Manual for further information.
