J2 – Encoder
J2 is a 20 pin female mini-D ribbon connector (AMP 2-178238-2). It
connects the motor encoder, hall effect switches, and the thermostat to
the ULTRA 200 Series drive. Contact between the connector shell and
a grounded chassis provides shield termination.
Allen-Bradley cables are available in various lengths for connecting
between J2 and an encoder. “Options and Accessories” on page A-1
lists the cables that are available. “J2 Terminal Strip/Breakout Board”
on page 6-30 details the optional signal extension kit.

Intro
ATTENTION: Ensure that the encoder signals are con-
nected as shown in Figure 6.36. Incorrect connection of the
encoder signals will result in improper rotor position, incor-
rect commutation and/or a runaway motor condition.
