Default
When a drive function defaults, it automatically changes to a
pre-programmed setting.
Enable Input
The Enable Input is a terminal connection on the L Option Board.
This connection provides an external input to enable or disable the
Drive Output section. It must be true to permit the drive to operate.
False
False refers to a logical false state. For instance, an L Option signal
on TB3 is false when the input contact is open or the appropriate
voltage is not applied to the L Option Board.
Jumper
A jumper completes a circuit between two pins within a male
connector on a drive board. In the absence of certain optional
equipment using female connectors, jumpers are applied to certain
pins within a male connector to complete specific and necessary
circuits.
L Option Board
An L Option Board plugs into connectors J7 and J9, located on the
lower portion of the Control Board. This board is identified as L4,
L5, L6, L7E, L8E, or L9E and provides optional control wiring
configurations for a drive.
Parameter

operating functions or status displays of a drive. Refer to 1336
IMPACT Adjustable Frequency AC Drive User Manual for
parameter details.
