1. The dynamic braking (DB)
optional unit [VFDB2009]
malfunctions.
Replace the dynamic
braking (DB) optional unit
[VFDB2009].
[Contents]
It starts when the dynamic
braking (DB) optional unit
[VFDB2009] is in the
protection state or has a
communication
abnormality.
* A number in the
rightmost digit
distinguishes the
dynamic braking (DB)
optional units
[VFDB2009] (1 through
6).
2. The connection cable between
the printed board
[VFDB2009-Z] on the dynamic
braking (DB) optional unit
[VFDB2009]and the gate
printed board [GAC66-Z] of
VF66B (DC motor drive) is
disconnected. The connector is
not inserted correctly.
Check that the connector is
inserted correctly.
Replace the connection
cable.
