3.6 Connecting Regenerative Resistors
If the built-in regenerative resistor is insufficient, connect an external regenerative resistor by one of the fol-lowing methods and set the regenerative resistor capacity (Pn600). As for precautions on selecting a regenera-tive resistor and its specifications, refer to Σ-V Series Product Catalog (No.: KAEP S800000 42).
3.6.1 Connecting Regenerative Resistors
The following instructions show how to connect the regenerative resistors and SERVOPACKs.
(1) SERVOPACKs: Model SGDV-R70F, -R90F, -2R1F, -2R8F, -R70A, -R90A, -1R6A, -2R8A
Connect an external regenerative resistor between the B1/ and B2 terminals on the SERVOPACK. After connecting a resistor, select the capacity. For more information on how to set the capacity of regenerative resistors, refer to 3.6.2 Setting Regenerative Resistor Capacity.
(2) SERVOPACKs: Model SGDV-3R8A, -5R5A, -7R6A, -120A, -180A, -200A, -330A, -1R9D, -3R5D, -5R4D, -8R4D, -120D, -170D
Disconnect the wiring between the SERVOPACK’s B2 and B3 terminals and connect an external regenerative resistor between the B1/ and B2 terminals. After connecting the resistor, select the capacity. For more infor-mation on how to set the capacity of regenerative resistors, refer to 3.6.2 Setting Regenerative Resistor Capac-ity.
Note: Be sure to take out the lead wire between the B2 and B3 terminals.
WARNING
• Be sure to connect the regenerative resistor correctly. Do not short-circuit between B1/ and B2.
Doing so may result in fire or damage to the regenerative resistor or SERVOPACK.

No built-in regenerative resistor is provided, so the external regenerative resistor is required. The regenerative resistor units are as follows:
Note: The regenerative resistor unit is constructed from a number of resistors.
Connect the B1/ and B2 terminals of the SERVOPACK to the R1 and R2 terminals of the regenerative resis-tor unit.
Use Pn600 at the factory setting when you use a Yaskawa regenerative resistor unit. Set Pn600 when using a non-YASKAWA external regenerative resistor.

3.6.2 Setting Regenerative Resistor Capacity
When a non-Yaskawa external regenerative resistor is connected, always set Pn600 (Regenerative Resistor Capacity) to the resistor capacity.
Be sure to set the regenerative resistor capacity (Pn600) to a value that is in accordance with the allowable capacity of the actual external regenerative resistor being used.
The setting will vary with the cooling method of external regenerative resistor:
• For natural convection cooling: Set the value to a maximum 20% of the actually installed regenerative resistor capacity (W).
• For forced convection cooling: Set the value to a maximum 50% of the actually installed regenerative resistor capacity (W).
Example: Set 20 W (100 W × 20%) for the 100-W external regenerative resistor with natural convection cooling method:
Pn600 = 2 (unit: 10 W)
Note 1. If Pn600 is not set to the optimum value, alarm A.320 will occur.
2. When set to the factory setting (Pn600 = 0), the SERVOPACK’s built-in resistor or Yaskawa’s regenerative resis-tor unit has been used.
WARNING
• If Pn600 is set to 0 when a non-Yaskawa external regenerative resistor is connected, regenerative over-load alarms (A.320) may not be detected. If the regenerative overover-load alarm (A.320) is not detected cor-rectly, the external regenerative resistor may be damaged and an injury or fire may result.

• When the external regenerative resistors for power are used at the rated load ratio, the resistor temperature increases to between 200 and 300°C. The resistors must be used at or below the rated values. Check with the manufacturer for the resistor’s load characteristics.
• For safety, use the external regenerative resistors with thermoswitches.

3.7 Noise Control and Measures for Harmonic Suppression
This section describes the wiring for noise control and the DC reactor for harmonic suppression.
3.7.1 Wiring for Noise Control
The SERVOPACK uses microprocessors. Therefore it may receive switching noise from peripheral devices.
To prevent the noise from the SERVOPACK or the peripheral devices from causing a malfunction of any one of these devices, take the following precautions against noise as required.
• Position the input reference device and noise filter as close to the SERVOPACK as possible.
• Always install a surge absorber in the relay, solenoid and electromagnetic contactor coils.
• Do not bundle or run the main circuit cables together with the I/O signal cables or the encoder cables in the same duct. Keep the main circuit cables separated from the I/O signal cables and the encoder cables with a gap of at least 30 cm.
• Do not use the same power supply as electric welders, electrical discharge machines, and similar devices. If the SERVOPACK is placed near equipment that generates high-frequency noise, install a noise filter on the input side of the main circuit power supply cable and control power supply cable, even if the same power supply is not used. Refer to (1) Noise Filter for the noise filter connection method.
• Take the grounding measures correctly. As for the grounding, refer to (2) Correct Grounding.
• Because the SERVOPACK is designed as an industrial device, it provides no mecha-nism to prevent noise interference.
• The SERVOPACK uses high-speed switching elements in the main circuit. Therefore peripheral devices may receive switching noise. If the equipment is to be used near private houses or if radio interference is a problem, take countermeasures against noise.
• If installation conditions by the EMC directive must be met, refer to 2.4 EMC Installa-tion CondiInstalla-tions in Σ-V Series User's Manual Setup Rotational Motor (No.: SIEP S800000 43).
