Connecting Regenerative Resistors
If the capacity to absorb regenerative energy is insufficient, use the following proce-
dure to connect an external regenerative resistor and set the regenerative resistor
capacity in the parameter Pn600.
To learn how to select a regenerative resistor, and for detailed specifications, refer to
Σ -V Series Product Catalog (No.: KAEP S800000 42).
3.4.1 Connecting Regenerative Resistor
This section describes how to connect a regenerative resistor.
(1) SERVOPACKs: Model SGDV-R70F, R90F, 2R1F, 2R8F, R70A, R90A,
1R6A, or 2R8A
Connect an external regenerative resistor between B1/ and B2 terminals. After
connecting a resistor, set the regenerative resistor capacity. Refer to 3.4.2 Setting the
Regenerative Resistor Capacity for information on how to set the regenerative resis-
tor capacity.
WARNING
• Be sure to connect the regenerative resistor correctly. Do not short-circuit
between B1/ ⊕ and B2.
Failure to observe this warning may result in fire or damage to the regenerative resistor or
SERVOPACK.
