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.
Use Pn600 at the factory setting when you use a Yaskawa regenerative resistor unit. Set Pn600 when using a
non-YASKAWA external regenerative resistor.
