3-8
(4) Power Supply Capacities and Power Losses
The following table shows the SERVOPACK’s power supply capacities and power losses.
∗1.
The value in parentheses is for the JUSP-RA04-E regenerative resistor unit.
∗2.
The value in parentheses is for the JUSP-RA05-E regenerative resistor unit.
∗3.
The value in parentheses is for the JUSP-RA18-E regenerative resistor unit.
∗4.
The value in parentheses is for the JUSP-RA19-E regenerative resistor unit.
Note 1. SGDV-R70F, -R90F, -2R1F, -2R8F, -R70A, -R90A, -1R6A, and -2R8A SERVOPACKs do not have built-in
regenerative resistors. Connect an external regenerative resistor if the regenerative energy exceeds the specified
value.
2. SGDV-470A, -550A, -590A, -780A, -210D, -260D, -280D, and -370D SERVOPACKs do not have built-in
regenerative resistors. Make sure that a regenerative resistor unit or an external regenerative resistor is connected.
Refer to
3.7 Connecting Regenerative Resistors
for details.
3. Regenerative resistor power losses are the allowable losses. Take the following actions if this value is exceeded.
• Remove the lead or shorting bar between terminals B2 and B3 on the SERVOPACK main circuit for SGDV-
3R8A, -5R5A, -7R6A, -120A, -180A, -200A, -330A, and 400-V SERVOPACKs.
• Install an external regenerative resistor. Refer to
3.7 Connecting Regenerative Resistors
for details.
