Wiring and Connection
SERVOPACKs: Model SGDV-470A, 550A, 590A, 780A, 210D, 260D,
280D, 370D
No built-in regenerative resistor is provided, so the external regenerative resistor is
required. The regenerative resistor units are as follow:
Connect a regenerative resistor unit between B1/ and B2 terminals.
When using a regenerative resistor unit, set Pn600 to 0 W (factory setting).
