Selecting and Connecting a Regenerative Resistor Unit

The SERVOPACKs and converters do not contain a regenerative resistor. Select and connect a regenerative
resistor unit and set the regenerative resistor capacity in Pn600 as described in this section.
For detailed specifications of the regenerative resistor units, refer to Large-Capacity
KAEP S800000 86).
• Be sure to connect the regenerative resistor unit correctly. Do not short-circuit between B1 and B2.
Doing so may result in fire or damage to the regenerative resistor unit, SERVOPACK, or converter or other devices.
3.8.1

Selecting a Regenerative Resistor Unit

(1) Using a Regenerative Resistor Unit Specified by Yaskawa
The regenerative resistor units specified by Yaskawa are listed in the following table. You must acquire the
regenerative resistor units separately.
If you use a regenerative resistor unit specified by Yaskawa, use it only in one of the combinations that are
given in the following table.
Main Circuit
Power Supply
Voltage
Three-phase
200 V
Three-phase
400 V
(2) Using a Non-Specified Regenerative Resistor Unit
If you use non-specified regenerative resistor units, contact your Yaskawa representative or the sales depart-
ment for more details.

If you use a non-specified regenerative resistor unit, we recommend that you use a
regenerative resistor unit with a thermal switch for safety.
