To properly use the product, read this manual thoroughly and retain

for easy reference, inspection, and maintenance. Ensure the end user

receives this manual.

MANUAL NO. TOBP C720600 00F

PREFACE

Braking resistor unit and braking unit are used to con-sume regenerative

energy from motor in the braking resistor unit at deceleration and to

improve the transis-tor inverter braking ability.

Before using the braking resistor unit and braking unit, a thorough under-

standing of this manual is recom-mended. This instruction manual will be

of great help for daily maintenance, inspection and troubleshoot-ing.

Inverters to which the braking resistor unit and braking unit can be con-

nected are of the following series:

• YASKAWA AC Drive 1000 Series

• Varispeed Series

Wiring sequence should shut off power to the drive when a braking

resistor Overload Relay Trip Contact (Thermal Protector Contact)

output is triggered.

General Precautions

SSome drawings in this manual are shown with the protective cover or shields

removed, in order to describe with more clarity. Make sure all covers and

shields are replaced before operating this product.

SSince the drawings in this manual are represented examples, some are subject

to differ from delivered products.

SThis manual may be modified when necessary because of improvement of the

product, modification or changes in specifications. Such modifications are

denoted by a revised manual No.

STo order a copy of this manual, if your copy has been damaged or lost, contact

your YASKAWA representative.

SYASKAWA is not responsible for any modification of the product made by the

user since that will void your guarantee.

NOTES FOR SAFE OPERATION

Read this instruction manual thoroughly before installation, operation,

maintenance or inspection of the braking unit and the braking resistor unit. In this

manual, NOTES FOR SAFE OPERATION are classified as “WARNING” or

“CAUTION.”

Indicates a potentially hazardous situation which, if not avoided, could result in

death or serious injury to personnel.

Indicates a potentially hazardous situation which, if not avoided, may result in

minor or moderate injury to personnel and damage to equipment.

It may also be used to alert against unsafe practices.

Even items described in CAUTION may result in a vital acci-

dent in some situations. In either case, follow these important notes.

: These are steps to be taken to insure proper operation.

WIRING

(Ref. page)

• Only commence wiring after verifying that the power sup-

ply is turned OFF.

Failure to observe this warning can result in an electrical shock

or a fire.

27

• High voltage exists at all terminals of braking unit and

braking resistor unit.

Failure to observe this warning can result in an electrical shock.

27

• Wiring should be performed only by qualified personnel.

Failure to observe this warning can result in an electrical shock

or a fire.

27

• Wiring sequence should shut off power to the drive when

a braking resistor Overload Relay Trip Contact (Thermal

Protector Contact) output is triggered.

Failure to observe this warning can result in a fire.

27

• When wiring the emergency stop circuit, check the wiring

thoroughly before operation.

Failure to observe this warning can result in personal injury.

27

• Make sure to ground the ground terminal.

(Ground resistance

200V class: 100Ω. or less, 400V class: 10Ω. or less)

Failure to observe this warning can result in an electrical shock.

27

• Short Circuit Current Rating (SCCR)

Install adequate branch short circuit protection according to applicable

codes. Failure to comply could result in damage to the drive. The device is

suitable for circuits capable of delivering 31,000 RMS symmet-rical

Amperes, 240 Vac maximum (200V Class), 480 Vac maximum (400V Class)

and 575Vac (600V Class) or the SCCR rating of the drive it is connected to,

which ever is greater.

WARNING

8

CAUTION

(Ref. page)

SVerify that the rated voltage of the braking unit and the braking

resistor unit coincides with the AC power supply voltage.

Failure to observe this caution can result in personal injury or a fire.

27

SDo not perform a withstand voltage test of the braking unit and

braking resistor unit.

It may cause semi−conductor elements to be damaged.

27

SConnect braking resistors, braking resistor units, and braking

units as shown in the I/O wiring examples. Use properly rated

wire in accordance with table 2 on page 31.

Otherwise, a fire can occur.

27

STighten terminal screws to the specified tightening torque.

Failure to observe this caution can result in a fire.

27

SBe sure to connect braking resistors or braking resistor units

to the braking units.

If neither braking resistor nor braking resistor unit is connected to a

braking unit, the fault contact may instantaneously turn ON when

the power is turned ON, resulting in malfunction of the inverter.

OPERATION

WARNING

(Ref. page)

SOnly turn ON the input power supply after replacing the front

cover. Do not remove the cover while current is flowing.

Failure to observe this warning can result in an electrical shock.

41

CAUTION

(Ref. page)

SNever touch the heatsink or discharging resistor since the

temperature is very high.

Failure to observe this caution can result in harmful burns to the

body.

41

SDo not check signals during operation.

The machine or the inverter may be damaged.

41

SAll the constants ofthe the braking unit andthe braking resistor

unit have been preset at the factory. Do not change the

settings unnecessarily.

41

11

CAUTION

(Ref. page)

SThe control PC board employs CMOS ICs. Do not touch the

CMOS elements.

They are easily damaged by static electricity.

46

SDo not connect or disconnect wires or connectors while power

is applied to the circuit.

Failure to observe this caution can result in personal injury.

46

OTHERS

WARNING

SNever modify the product.

Failure to observe this warning can result in an electrical shock or

personal injury and will invalidate the guarantee.

1 RECEIVING

The braking resistor unit and braking unit have been put through severe tests at

the factory before shipment. After unpacking, however, check and see the follow-

ing. If any malfunctions are found, contact your YASKAWA representative.

• Their nameplate data meet your requirements.

• They have sustained no damage while in transit.

• Fastening bolts and screws are not loose.

1.1 NAMEPLATE

(1) NAMEPLATE INFORMATION (BRAKING UNIT)

(2) NAMEPLATE INFORMATION (BRAKING RESISTER UNIT)

• Do not install and attempt to use a braking resistor or braking resis-

tor unit If there are any damaged or missing components.

Failure to comply can result in personal injury.

For long term storage, the unit should be kept in a clean area

indoors.

2 INSTALLATION

2.1 LOCATION

If the units are temporarily stored or machine stops for an extended length of

time, the following precautions should be taken. Store the units at pollution level

2 or less (UL standard) and under the following conditions.

• Free from rainfall and drops of water.

• Clean and dry.

• Free from corrosive gases and liquids.

• Free from dirt and dust.

• Ambient temperature: 14 to 104°F, 10 to 40°C.

• Humidity: 90% RH or less (no condensation)

• Free from vibration.

2.2 INSTALLATION

For full use of the braking resistor unit or braking unit functions, install the units

at pollution level 2 or less (UL standard) and in a location to satisfy the following

conditions:

Figs. 1 to 8 show the external dimensions and the spaces from the periphery.

• Provide the spaces shown in Figs. 1 to 8 between the units and the

periphery.

• Since the braking resistor unit generates heat, provide sufficient

spaces from devices which are weak against heat.

• Install the units at such locations that all requirements described in

Par. 2.1 “LOCATION” are satisfied.

2 INSTALLATION

17

• Install the units in the directions shown in Figs. 1 to 8. There will be

no problem if they are installed vertically.
