Wiring and Connection
(3) SERVOPACKs: Model SGDV-470A, 550A, 590A, 780A, 210D, 260D, 280D, 370D
No built-in regenerative resistor is provided, so an external regenerative resistor unit is required. The regener-
ative resistor units are as follows:
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.
