3.4 WIRING PRECAUTIONS

(1) Wiring Leading−in Method

Lead in the wire through the knockout hole on the unit bottom. Since the
knockout hole is provided with a rubber bush, cut the rubber bush central
crosswise with a blade and lead the wire through.

(2) Separation from Signal Lines

Since strong noise component is superimposed on the braking resistor unit
and braking unit wiring, separate the units from signal lines which are weak
against noise.

(3) Wiring Distance

Wiring distance between the braking resistor unit and braking unit or braking
unit and inverter must be provided as shown in Fig. 13. Make sure to bundle
the wires between the units.

3. WIRING

(4) Grounding Method

: Mount the braking resistor unit on a grounded metallic plate. When it can-

not be mounted on a grounded metallic plate, pull out the lead wire from
the mounting screw section to ground.

:

Braking unit grounding terminal must be provided with class 3 ground
(ground resistance: 100Ω or less.)

: Use the sizes specified in “INTERNAL CONNECTION SPECIFI-

CATIONS” for grounding cables.

3.5 INTERCONNECTION

Figs. 14 to 20 show the interconnecting diagrams of the braking unit or braking re­sistor unit and VS−616G5.

Refer to Par.3.3, “Wiring Precautions” for proper wiring in actual wiring design and
work.

Be sure to connect braking resistors or braking resistor units to the braking units.

Connect only braking resistors or Braking Resistor Units (LKEB−XXXX) to Brak-
ing Units.

NOTE

If using another braking resistor instead of YASKAWA braking resis­tor unit, be sure to protect by thermal overload relay.

4.3 MASTER/SLAVE SELECTION CONNECTOR SETTING

Selection Connector Setting MASTER side is selected prior to shipment. Use the
units without changing the setting.

SLAVE side is selected when more than one braking unit is combined to use and
braking start levels must coincide. Refer to Par. 4.4, “Parallel Connection of Brak­ing Unit” for details.

4.4 PARALLEL CONNECTION OF BRAKING UNIT

For using more than one parallel−connected braking unit, connect and select the
connectors as follows. (See Fig. 23.)

:

Braking units have a MASTER/SLAVE selection connector. (See Fig.

10.) Select MASTER side only for braking unit 1 and select SLAVE side
for braking units 2 and 3.

:

Connect thermal protector on the braking resistor unit and thermoswitch
on the braking unit in parallel. Refer to Figs. 15 and 18 for proper wiring.

: Use properly rated wire in accordance with table 2 on page 31.

: Use twisted−pair wires of 1mm or less for connection between 5, 6 and

1, 2 of the braking units.

:

Parallel connection of braking unit is possible up to a maximum of 10
units.
