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 more information.
