This parameter is used to select the source of the start/stop command and direction control. The following

settings are available:

 LOCAL  START/STOPandFORWARD/REVERSEcommandsfromthekeypadonly.

REMOTE START/STOP and FORWARD/REVERSE commands from the terminal strip only.

BOTH LOCAL operation if TB-13A or TB-13C is programmed for LOCAL SELECT and a

contact closure is made from TB-13A or TB-13C to TB-2. If the contact closure is not

made, the drive will be in REMOTE mode.
