(2) Specifications of Built-in Regenerative Resistor
If the amount of regenerative energy exceeds the processing capacity of the SERVOPACK, then install an exter-
nal regenerative resistor. The following table shows the specifications of the SERVOPACK’s built-in resistor and
the amount of regenerative power (average values) that it can process.
* 1. The average regenerative power that can be handled is 20% of the rated capacity of the regenerative
resistor built into the SERVOPACK.
* 2. The values in parentheses are for the optional JUSP-RA04 Regenerative Resistor Unit.
* 3. The values in parentheses are for the optional JUSP-RA05 Regenerative Resistor Unit.
