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 Types are equipped with the drive cutoff relay mounted inside the controller.)
Note 3 CGB/LCG Types are not equipped with a relay to enable to automatically identify a
teaching tool was inserted and switch the wiring layout. (It does not get short-circuited
between S1 and S2 terminals even if not connected.)
The controller on CB/LC Types automatically identifies that a teaching tool was inserted.
(When there is nothing plugged in, S1 and S2 are short-circuited inside the controller.)
Note 4 Since there is no motor power cutoff relay in CGB/LCG Types, make sure to establish a
cutoff relay externally.
