and selection are indicated on the following pages. Refer to the 1336
Closure Interface Board (cont.)
Programming Manual to verify that the drive is programmed to meet your
requirements.
If two-wire control is installed, option L1, L2 or L3 must also be installed.
The 2-wire scheme allows a fault to be cleared by cycling the start/stop
contact if the following is true:
•
Parameter 14 = 1
•
Parameter 39 = 1
If Parameter 14 is not set to “1”, the drive can remain in an “F11” loop.
Power must then be cycled in order to clear the fault.
!
ATTENTION: Unexpected machine motion can cause injury or
death. Do not use a Local or Remote Control Panel with option L1,
L2, or L3 in any 2-wire start/stop control application.
A maintained start command or 2-wire control between terminals
19 and 20 of TB3 on option L1, L2 or L3 will affect Control Panel
stop pushbutton operation. The drive will automatically restart after
the Control Panel stop pushbutton is depressed and released.
