External Regenerative Resistors
Regenerative resistors for servo amplifiers are internally
or externally mounted, as shown in the following table.
They can be mounted externally on all servo amplifiers,
but are especially effective when regenerative energy
exceeds the servo amplifier’s capacity.

When mounted externally, be sure to remove the jumper
between B2 and B3, which deactivates the internal
regenerative resistor.
Important: External regeneration resistor sizing and
amplifier set-up will be important for proper operation.
Use Yaskawa’s SigmaSize and the Sigma II Series

* Capacity prior to derating. If regeneration power require-

resistance). Be sure to derate wattage of external resistor
to 20% or less (natural convection) and of 50% or less with
forced air cooling.

DB Units (For large capacity servo systems)
Externally attach a DB unit to the servopack.
This DB unit is used for dissipating motor EMF energy.
The DB unit does not need to be installed if the dynamic brake function is not required.
• Specifications
Use one of the following DB units according to the servopack model.
Servopack Model SDGH- 2BDE 3ZDE 3GDE 4EDE 5EDE
Regenerative DB Unit JUSP- DB03 DB04 DB05 DB06

Control of Harmonic Frequency in the Power Supply Circuit
If harmonic frequency control is needed in the power supply, connect a DC reactor between terminals
(+) 1 and (+) 2 on the servo amplifier’s main circuit. Use the following table as a guide for selection of
the appropriate reactor.
