Note 1)Please press the ON switch for the main power for at least 2 seconds, as the alarm signal input

takes 1~2 seconds after the main power is turned on.

Note 2)100[W]~400[W]drive has built-in recovery resistance of 50[W], 100[Ω]; 800[W]~1[kW]drive has

100[W], 40[Ω]; and 2[kW]~ 3.5[kW]drive has 150[W], 13[Ω] recovery resistance. Please use them

by shorting terminals B and BI. If the recovery resistance is high due to frequent

acceleration/deceleration, please open the shorting pins (B, BI) and connect external recovery

resistance to B, B+.

Note 3)Please peel off the 7~10[mm] of the sheath of the power cable to be used for the power unit as

shown in the figure below. And use the dedicated pressure terminal (see “2.4.2 Power Circuit

Electronics Specifications”)

Note 4)When removing power unit wiringfrom 100[W]~1[kW] drive, remove or connect it after pressing

the button at the drive’s terminal block. In case of 2[kW]~3.5[kW] drive, remove or connect it using

a flat-head driver.
