3 Wiring and Connection
3.6.1 Connecting Regenerative Resistors
3-44
(3) SERVOPACKs: Model SGDV-550A and -260D
No built-in regenerative resistor is provided, so the external regenerative resistor is required. The regenerative
resistor units are as follows:
Note: The regenerative resistor unit is constructed from a number of resistors.
Connect the B1/ and B2 terminals of the SERVOPACK to the R1 and R2 terminals of the regenerative resis-
tor unit.
When using a regenerative resistor unit, leave Pn600 at its facto
ry setting. Set Pn600 when using a non-YAS-
KAWA external regenerative resistor.
