Wiring and Connection
3.8.2 Connecting a Regenerative Resistor Unit
Connect the B1 terminals and connect the B2 terminals between the converter and regenerative resistor unit.
Connect them as shown in the following figures.
3.8.3 Setting Regenerative Resistor Capacity
(1) Using a Regenerative Resistor Unit Specified by Yaskawa
 Using a Specified Combination
If you use a regenerative resistor unit specified by Yaskawa in one of the specified combinations, use the fac-
tory setting for Pn600.
 Using a Non-Specified Combination
If you use a non-specified combination, refer to (2) Using a Non-Specified Regenerative Resistor Unit.
(2) Using a Non-Specified Regenerative Resistor Unit
If you use a non-specified regenerative resistor unit or if you use a regenerative resistor unit specified by
Yaskawa but do not use it in the specified combination, set the capacity of the resistor in Pn600 (Regenerative
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 regenerative resistor unit being used.
• 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).

WARNING
• If you set Pn600 to 0 when a non-specified regenerative resistor unit is connected or when a regenerative
resistor unit specified by Yaskawa is connected in a non-specified combination, regenerative overload
alarms (A.320) may not be detected. If the regenerative overload alarm (A.320) is not detected correctly,
the regenerative resistor may be damaged and an injury or fire may result. Always set Pn600 to a suitable
value.
