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, because XDL-L7NHB010U(100[W], 100[ Ω ]) and
XDL-L7NHB020U~ XDL-L7NHB035U(150[W], 40[ Ω ]) have internal regenerative resistance. If the
regenerative capacity is high because of frequent acceleration and deceleration, open the
short-circuit pins (B , BI) and connect an external regenerative resistor to B and B+.
Note 3) Remove approximately 7-10
㎜
of the sheathing from the cables for the main circuit
power and attach crimp terminals. (Refer to Section 2.4.2, "Power Circuit Electrical
Components.”)
Note 4) Use a (-) flathead screwdriver to connect or remove the main circuit power unit wiring.
