Note a) Power loss of regenerative resistor is allowable loss. If the loss exceeds the
allowable loss, the regenerative resistor inside the SERVOPACK should be
removed and connected externally. Because the model in which the regenera-
tive resistor is externally connected falls into non-standard specification cate-
gories, contact YASKAWA for further information.
For this non-standard type, “Y8” is appended to the end of the standard model
number.
b) For SGDB-60AD to 1EADj models, the regenerative resistor is placed sepa-
rately. The regenerative resistor unit provided from YASKAWA is described in
Section 3.8.4 Using Regenerative Resistor Units. Its power loss for
SGDB-60ADj is 180W (type: JUSP-RA04), and for SGDB-75ADj and
-1EADj is 350W(type: JUSP-RA05).
