WIRING
CAUTION
• To emphasize connection of master/slave operation in this diagram, other
connections are not shown. When actually connecting units, configure a
circuit which prevents resistor overheat as shown in a connection example
"When connecting several brake units to one inverter" on page 25 .
• When replacing from the exisiting MT-BU5 type brake unit, set "2" in
Pr.0
Brake
mode switchover (refer to page 33)
, "1" in Pr.30 Regenerative function selection
and "10%"
in Pr.70 Special regeneration brake duty (refer to the inverter manual) of
the inverter.
• Do not run the MT-BU5 type brake unit and FR-BU2 in parallel. Doing so
could cause an alarm or brake unit failure. Use the FR-BU2 only when
performing parallel operation.
