Note1. The CW limit input signal and CCW limit input signal can be
input through an Input Unit. The following flags function as
the CW/CCW limit input signals in the CJ1M:
Pulse Output 0: CW: A540.08, CCW: A540.09
Pulse Output 1: CW: A541.08, CCW: A541.09
Program the actual inputs from the Input Unit to control these
flags as ladder program outputs as shown below.
Note2. The XB contacts are used to turn ON/OFF the electromag-
netic brake.
a) Do not connect anything to unused terminals.
b) The 0 V terminal is internally connected to the common
terminals.
c) The following crimp terminal is applicable:
R1.25-3 (round with open end).
