<1> Use the specified AC reactor and fuse. Non-specified devices may cause erroneous operation.
<2> Always take the power supply for the drive’s AC power supply terminals (R/L1, S/L2, and T/L3) from the secondary side of the
power coordinating reactor.
<3> Always take the power supply for the unit’s power supply voltage detection inputs (r1/ 11, 1/ 21, and t1/ 31) from the primary
side of the power coordinating reactor.
<4> Do not use a DC bus line that is longer than 5 m to connect the regenerative unit and drive.
<5> Do not use a line longer than 10 m to connect the power coordinating reactor and the regenerative unit.
<6> The connections are shown for sequence connections with no-voltage contacts or NPN transistors for the sequence input signals (S1
to S8). Use jumper S3 to select between Sink mode and Source mode. The default setting is Sink mode.
<7> Multi-function analog outputs work with devices such as analog frequency meters, ammeters, voltmeters, and wattmeters. They are
not intended for use as a feedback-type signal.
