Single-phase AC Power Supply Input/Three-phase AC
Power Supply Input Setting
Some models of Three-phase 200-VAC SERVOPACKs can also operate on a single-phase
200-VAC power supply.
You can use a single-phase, 200-V power supply input with the following models.
• SGD7S-R70A, -R90A, -1R6A, -2R8A, and -5R5A
If you use a single-phase, 200-VAC power supply input for the SERVOPACK’s main circuit
power supply, set parameter Pn00B to n.1 (Use a three-phase power supply input as a
single-phase power supply input).
Refer to the following section for information on wiring a single-phase AC power supply input to
the SERVOPACK.
• Wiring Example for Single-Phase, 200-VAC Power Supply Input on page 4-18
You do not need to change the setting of Pn00B to n.1 (Use a three-phase power sup-
ply input as a single-phase power supply input) for a SERVOPACK with a single-phase 200-
VAC power supply input (model numbers: SGD7S-120AE0A008) or for a SERVOPACK with a
single-phase 100-VAC power supply input.

Use a three-phase power supply input and
as a single-phase power supply input.
1. If you use a single-phase power supply input without specifying a single-phase AC power sup-
ply (Pn00B = n.1), an A.F10 alarm (Power Supply Line Open Phase) will occur.
2. Not all SERVOPACKs can be run on a single-phase AC power supply input. If you connect a
single-phase AC power supply input to a SERVOPACK that does not support single-phase
power, an A.F10 alarm (Power Supply Line Open Phase) will occur.
3. If you use a single-phase 200-VAC power supply input, the torque-motor speed characteristic
of the Servomotor will not be the same as for a three-phase AC power supply input. Decide
whether to use a single-phase or three-phase AC power supply input after checking the char-
acteristics given in the Servomotor manual or catalog.
