Replacement with the old model DB unit
8.1
Replacement with VFDB2002 series
VFDB2009 series power dynamic brake system has compatibility in VFDB2002 series power dynamic brake
system, attachment, and an operating method. When you exchange VFDB2002 series to VFDB2009 series,
please make wiring and a setup of VFDB2009 the same as VFDB2002. ( Refer to "8.3 Parallel operaton
method with VFDB series."
)
Furthermore, VFDB2002 series and VFDB2009 series are mixed and a parallel operation is possible. In this
case, make wiring and a setup of VFDB2009 the same as VFDB2002.
※
In VFDB2002 series and VFDB2009 series differs from to change of power supply voltage, to select of
power supply series and to set of voltage width which stops DB operation. For details, refer to the
instructions manual of VFDB2002 series.

Replacement with VFDB5022,VFDB5044,VFDB91-200
Connection, operation method and the operation / setting method differ from by VFDB2009 series and
VFDB5022VFDB5044VFDB91-200. When exchanging to VFDB5022, VFDB5044, and VFDB91-200 to
VFDB2009 series, it is necessary to change wiring with an inverter. Refer to "3.2 Connection" for wiring of
VFDB2009.
In addition, please keep in mind that it cannot perform the parallel run of VFDB2009 series, and VFDB5022,
VFDB5044 and VFDB91-200.
