1 YASKAWA FOR VARISPEED-600 SERIES INVERTER BRAKING UNIT BRAKING RESISTOR UNIT INSTRUCTIONS MODEL: BRAKING UNIT CDBR- BRAKING RESISTOR UNIT LKEB- Upon receipt of the product and prior to initial operation, read these instructions thoroughly, and retain for future reference. YASKAWA MANUAL NO. TOBP C A

2 PREFACE Braking resistor unit and braking unit are used to consume regenerative energy from motor in the braking resistor unit at deceleration and to improve the transistor inverter braking ability. Before using the braking resistor unit and braking unit, a thorough understanding of this manual is recommended. This instruction manual will be of great help for daily maintenance, inspection and troubleshooting. Inverters to which the braking resistor unit and braking unit can be connected are of the following series: D VS 616 Series D VS 676 Series D VS 866 Series 3

3 General Precautions S Some 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. S Since the drawings in this manual are represented examples, some are subject to differ from delivered products. S This 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. S To order a copy of this manual, if your copy has been damaged or lost, contact your YASKAWA representative. S YASKAWA is not responsible for any modification of the product made by the user since that will void your guarantee. 4

4 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. WARNING Indicates a potentially hazardous situation which, if not avoided, could result in death or serious injury to personnel. CAUTION 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. CAUTION Even items described in may result in a vital accident in some situations. In either case, follow these important notes. NOTE : These are steps to be taken to insure proper operation. 5

6 WIRING WARNING S Only commence wiring after verifying that the power supply is turned OFF. Failure to observe this warning can result in an electrical shock or a fire. S High voltage exists at all terminals of braking unit and braking resistor unit. Failure to observe this warning can result in an electrical shock. S Wiring should be performed only by qualified personnel. Failure to observe this warning can result in an electrical shock or a fire. S When wiring the emergency stop circuit, check the wiring thoroughly before operation. Failure to observe this warning can result in personal injury. S Make sure to ground the ground terminal. (Ground resistance 200V class: 100W or less, 400V class: 10W or less) Failure to observe this warning can result in an electrical shock. (Ref. page)

7 CAUTION S Verify 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. S Do not perform a withstand voltage test of the braking unit and braking resistor unit. It may cause semi conductor elements to be damaged. S Connect 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. S Tighten terminal screws to the specified tightening torque. Failure to observe this caution can result in a fire. (Ref. page)

8 OPERATION WARNING S Only 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. (Ref. page) 41 CAUTION S Never 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. S Do not check signals during operation. The machine or the inverter may be damaged. S Alltheconstantsofthethebrakingunitandthe brakingresistor unit have been preset at the factory. Do not change the settings unnecessarily. (Ref. page)

10 CAUTION S The control PC board employs CMOS ICs. Do not touch the CMOS elements. They are easily damaged by static electricity. S Do not connect or disconnect wires orconnectors whilepower is applied to the circuit. Failure to observe this caution can result in personal injury. (Ref. page) OTHERS WARNING S Never modify the product. Failure to observe this warning can result in an electrical shock or personal injury and will invalidate the guarantee. 11

11 WARNING INDICATION A warning label is displayed on the front cover of the braking unit, as shown below. Follow these instructions when handling the braking unit and the braking resistor unit. Example of Braking Unit Model CDBR 4045B 12

31 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. Braking Resistor Unit Braking Unit Inverter 32.8ft (10m) or less 16.4ft (5m) or less Fig. 13 Wiring Distance 32

32 3.WIRING (4) Grounding Method S Mount the braking resistor unit on a grounded metallic plate. When it cannot be mounted on a grounded metallic plate, pull out the lead wire from the mounting screw section to ground. S Braking unit grounding terminal must be provided with class 3 ground (ground resistance: 100Ω or less.) S 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. Connectonlybrakingresistorsor BrakingResistor Units (LKEB XXXX) to Braking Units. NOTE If using another braking resistor instead of YASKAWA braking resistor unit, be sure to protect by thermal overload relay. 33

43 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.) S 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. S 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. S Use properly rated wire in accordance with table 2 on page 31. S Use twisted pair wires of 1mm or less for connection between 5, 6 and 1, 2 of the braking units. S Parallel connection of braking unit is possible up to a maximum of 10 units. 44
