Using the L Option 5-11
Using an Encoder with the
L Option Board If you have an L7E, L8E, and L9E board, you need to complete the
following steps to use the encoder:
1. Ground the encoder the cable shield.
2. Set the encoder voltage jumper to match the encoder used
(J1/J2:5V/12V) on the L Option board.
3. Connect phase A, phase A NOT, phase B, and phase B NOT.
4. Connect the power to the encoder.
Requirements for the Contact
Closure Interface Board (L4) Figure 5.4 shows the wiring diagram for the L4 Option board.

L4 Option Board Wiring Diagram
Circuits used with the L4 Option board must be able to operate with
low = true logic. Reed type input devices are recommended.
If your drive is a(n):
Ground the encoder to the following
location on the control board:
A1, A2, A3, or A4 frame J7 pin 9, 6, or 3
B, C, D, E, F, G, or H frame TB10 pin 20, 17, 12, 9, or 6

Be capable of a sinking current of approximately 10 mA to pull
the terminal voltage low to 3.0V DC or less.
high Let the terminal voltage rise to a voltage of 4.0 – 5.0V DC
