The official model number is SGDV-120A11A008000.
Note 1. SGDV-R70A, -R90A, -1R6A, and -2R8A SERVOPACKs do not have built-in regenerative resistors. If the regen-
erative energy exceeds the specified value, connect an external regenerative resistor between B1/
2. Regenerative resistor power losses are allowable losses. Take the following action if this value is exceeded.
• Remove the lead or shorting bar between terminals B2 and B3 on the SERVOPACK main circuit of SGDV-
5R5A, -120A SERVOPACKs.
• Install an external regenerative resistor between external regenerative resistor connection terminals B1/
B2.
3. External regenerative resistors are not included.
(6) How to Select Molded-case Circuit Breaker and Fuse Capacities

The official model number is SGDV-120A11A008000.
Note 1. To comply with the EU low voltage directive, connect a fuse to the input side as protection against accidents
caused by short-circuits. Select the fuse for the input side that are compliant with UL standards.
The table above also provides the net values of current capacity and inrush current. Select a fuse and a molded-
case circuit breaker which meet the breaking characteristics shown below.
• Main circuit, control circuit: No breaking at three times the current values shown in the table for 5 s.
• Inrush current: No breaking at the current values shown in the table for 20 ms.
2. The following restrictions apply to UL standard compliance conditions for SGDV-120A11A008000 SERVO-
PACKs.
• Current rating when using molded-case circuit breaker: 40 A max.
