Installing, Connecting and Using the Encoder Mod-
74 AX2550 Motor Controller User’s Manual Version 1.9b. June 1, 2007
Follow these simple steps to install:
1- With the power removed, remove the controller’s face plate and slide off the cover.
2- Carefully insert the encoder module on top of the two headers present on the control-
ler’s main board and shown in Figure 43. Beware that the two matting connectors are pre-
cisely aligned.
3- The encoder module will be held in place by the connectors and the new front bracket’s
opening around the RJ11 connector. For added stability, place the foam pad on top of the
Encoder module as shown in Figure 44 so that it is held in place by the sliding cover. For
use in harsh shock and vibration environments, you may instead solder a metal wire inside
the 0.1” hole found on the main board (next to one of the two header) and solder the other
en inside the matching hole on the encoder module, as shown on Figure 45.
