3 Wiring and Connection
3.7.1 Connecting Regenerative Resistors
(3) SERVOPACKs: Model SGDV-550A, 260D
No built-in regenerative resistor is provided, so an external regenerative resistor unit is required. The regener-
ative resistor units are as follows:
Main Circuit
Power Supply
Three-phase
200 V
Three-phase
400 V
Connect a regenerative resistor unit between the B1 and B2 terminals.
When using a regenerative resistor unit, use the factory setting for Pn600. If a non-Yaskawa regenerative resis-
tor is used, make the setting for Pn600.
