Wiring and Connection
(3) Wiring Example with Single-phase 200 V Power Supply Input
 Single-phase 200 V SERVOPACK SGDV-R70A, R90A, 1R6A, 2R8A, 5R5A
(4) 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.
Note 1. SGDV-R70A, R90A, 1R6A, and 2R8A SERVOPACKs do not have built-in regenerative resistors. If the regener-
ative energy exceeds the specified value, connect an external regenerative resistor.
2. Regenerative resistor power losses are allowable losses. Take the following action if this value is exceeded.
• Remove the lead from the internal regenerative resistor in the SERVOPACK. (SGDV-5R5A)
• Install an external regenerative resistor.
3. External regenerative resistors are options.
