Note 1 The power rating of the motor power-off relay turning ON/OFF with contact CR1 is 24V
DC and 10mA or less.
Note 2 Connect such as a connector to L1/L2 terminals when cutting off the motor power
source externally.
(CB/LC type are equipped with the drive cutoff relay mounted inside the controller.)
Note 3 CGB/LCG type are not equipped with a relay to enable to automatically identify a
teaching tool was inserted and switch the wiring layout. (The system I/O connector
does not get short-circuited between S1 and S2 terminals even if a teaching tool is
removed.)
The controller on CB/LC type automatically identifies that a teaching tool was inserted.
(Short-circuit is made between S1 and S2 terminals inside the controller once
connection is detected.)
Note 4 Since there is no motor power cutoff relay in CGB/LCG type, make sure to establish a
cutoff relay externally.
