1–3Control Logic Wiring and Adapters
Publication 1336 IMPACT-6.8 – November, 2002
The L Option Board provides a means of interfacing various signals
and commands to the 1336 IMPACT drive by using contact closures.
Six different versions of the L Option are available:
L4 Contact Closure Interface
1
L7E Contact Closure Interface with Encoder Feedback
1
L5 +24V AC/DC Interface
L8E +24V AC/DC Interface with Encoder Feedback
L6 115V AC Interface
L9E 115V AC Interface Interface with Encoder Feedback
1
Uses internal +5V DC supply.
The user inputs are connected to the L Option Board through TB3.
The L4, L5, and L6 options each have nine inputs: seven
user-configurable inputs and two factory-defined control inputs. The
function of each L Option must be selected through programming as
explained later in this section. The L7E, L8E, and L9E options are
similar to L4, L5, and L6 with the addition of encoder feedback
inputs.
Control Board Jumpers for L Option
Important: If the L Option Board is being installed, Control Board
jumpers at pins 3 & 4 and 17 & 18 of J2 must be
removed. If these jumpers are removed, they can be
stored on the “spares” location on the Control Board.
Refer to Figure 1.2. If the L Option board is removed,
these jumpers must be reinstalled, the L Option Mode
parameter must be programmed to “1” and the drive
power must be cycled.
Available Inputs
The L Option allows the combination of the following functions:
Accel/Decel Rates Process Trim
Digital Potentiometer (MOP) Ramp
Enable Reset
Flux Enable Run Forward
Forward/Reverse Run Reverse
Jog Speed Selects
Local Control Speed Torque Selections
Not Ext Flt Start
