(4) Wiring Example with Single-phase 200-V Power Supply Input
SERVOPACK with Single-phase, 200-V Power Supply
Applicable SERVOPACK Model: SGDV-R70A, -R90A, -1R6A, -2R8A, -5R5A, and -120A01A008000.
(5) Power Supply Capacities and Power Losses
The following table shows SERVOPACK’s power supply capacities and power losses when using single-
phase 200 V power supply.
∗ The official model number is SGDV-120A01A008000.
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/ and B2.
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/ and
B2.
3. External regenerative resistors are not included.
