5.8.6 External Regenerative Resistor
Regenerative resistors for SERVOPACKs are internally or externally mounted as shown in the table below.
Regenerative resistors can be externally mounted on all SERVOPACKs. Connect an external regenerative resis-
tor to the SERVOPACK if regenerative energy exceeds the capacity of the SERVOPACK.
If a regenerative resistor is to be mounted externally, the jumper between B2 and B3 for the internal regenerative
resistor must be removed. Refer to 6.5 Connecting Regenerative Resistors for the selection.
No built-in regenerative resistor is provided to 6 kW or more SERVOPACKs. Be sure to prepare the externally
mounted regenerative resistor.
The following table shows examples of regenerative resistors.
* 1. The values in parentheses are for the optional JUSP-RA04 Regenerative Resistor Unit.
* 2. The values in parentheses are for the optional JUSP-RA05 Regenerative Resistor Unit.
* 3. The values in parentheses are for the optional JUSP-RA18 Regenerative Resistor Unit.
* 4. The values in parentheses are for the optional JUSP-RA19 Regenerative Resistor Unit.
