12.8.4 Specifications of Built-in Regenerative Resistors in
SERVOPACKs
The following table gives the specifications of the built-in regenerative resistors in the SERVO-
PACKs and the amount of regenerative power (average values) that they can process.
*1. Values in parentheses are for the optional JUSP-RA04-E Regenerative Resistor Unit.
*2. Values in parentheses are for the optional JUSP-RA05-E Regenerative Resistor Unit.

Not pro-
vided.
Basically not
required.
There is no built-in regenerative resistor, but
normally an External Regenerative Resistor is
not required.
Install an External Regenerative Resistor when
the smoothing capacitor in the SERVOPACK
cannot consume all the regenerative power.

*1
Basically not
required.
A built-in regenerative resistor is provided as a
standard feature. Install an External Regenera-
tive Resistor when the built-in regenerative
resistor cannot process all of the regenerative
power.

Required.
*2
A built-in regenerative resistor is not provided.
An External Regenerative Resistor is required.
If the External Regenerative Resistor is not
connected to the SERVOPACK, a Regenera-
tion Alarm (A.300) will occur.
