8.3.3 Power Loss
Table 8.4 shows the power loss of the SERVOPACKS.

Note 1. The power loss of Regenerative Resistors is the permissible power loss. If the permissible power loss is
exceeded, remove the built-in Regenerative Resistor from the SERVOPACK and reinstall an external resis-
tor. A SERVOPACK with an external Regenerative Resistor is a nonstandard model("Y8" is added to the
end of the model number of a standard model.) For nonstandard SERVOPACK models, contact your nearest
Yaskawa sales representative.
2. For the SGDB-60AN to SGDB-1AAN models, the Regenerative Resistors are installed separately. The re-
generative resistor unit made available by Yaskawa is shown in 5.6.3 "Regenerative Resistor Unit". The
permissible power loss of the regenerative resistor (JUSP-RA04) for SGDB-60AN is 180 W, and that of the
Regenerative Resistor (JUSP-RA05) for SGDB-75AN and SGDB-1AAN is 350 W.
