1.
Connect the R1 and R2 terminals on the Regenerative Resistor Unit to the B1/ and B2
terminals on the SERVOPACK.
2.
Set Pn600 (Regenerative Resistor Capacity) and Pn603 (Regenerative Resistance) as
required.
•
When using the Yaskawa-recommended Regenerative Resistor Unit, use the default settings for
Pn600 and Pn603.
•
If you use any other external regenerative resistor, set Pn600 and Pn603 according to the specifica-
tions of the regenerative resistor.
Refer to the following section for details on the settings.

Wiring Reactors for Harmonic Suppression
You can connect a reactor for harmonic suppression to the SERVOPACK when power supply
harmonic suppression is required. Refer to the following manual for details on reactors for har-
monic suppression.
Σ
-7-Series Peripheral Device Selection Manual (Manual No.: SIEP S800001 32)
Refer to the following figures to connect reactors.
Note: 1. Connection terminals
1 and
2 for a DC Reactor are connected when the SERVOPACK is shipped.
Remove the lead wire and connect a DC Reactor.
2. Reactors are optional products. (Purchase them separately.)
3. You cannot connect a DC Reactor to a SERVOPACK with a single-phase, 100-VAC power supply input.
