NOTE 1) It takes approximately one to two seconds until alarm signal is output after you turn on the main
power. Accordingly, push and hold the main power ON switch for at least two seconds.
NOTE 2) Short-circuit B and BI terminals before use. Regenerative resistance of L7SA001

(150 [W], 13 [Ω]) exist inside. If
regenerative capacity is high because of frequent acceleration and deceleration, open the short-
circuit pins (B, BI) and connect external regenerative resistance to B and B+.
NOTE 3) Remove the sheath of cables to be used for the main circuit power by approximately 7-10 [

] and
use devoted crimp terminals. (Refer to “3.2.2 Power Circuit Electric Sub Assembly Standards.”)
NOTE 4) Connect or remove the main circuit power unit wiring after pushing the button of the L7SA001
