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 factory setting. Set Pn600 when using a non-

YASKAWA external regenerative resistor.
