6.3.3 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.
n SGD7S-R70A, -R90A, -1R6A, -2R8A, and -5R5A
If you use a single-phase, 200-VAC power supply input for the SERVOPACK’s main cir-
cuit power supply, change the setting to specify a single-phase AC power supply input
(Pn00B = n.1).
You do not need to change the setting of Pn00B to n.  1  (Use a
three-phase power supply input as a single-phase power supply input) for
a SERVOPACK with a single-phase 200-V power supply input (model
numbers: SGD7S-120A
 008) or for a SERVOPACK with a single-
phase 100-V power supply input.

After restart Setup
n.1
Use a three-phase
power supply input and
as a single-phase power
supply input.
– If you use a single-phase power supply input without specifying a
single-phase AC power supply (Pn00B = n.  1  ), an A.F10 alarm
(Power Supply Line Open Phase) will occur.
– 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 SER-
VOPACK that does not support single-phase power, an A.F10 alarm
(Power Supply Line Open Phase) will occur.
– 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 characteristics given in the Servomotor manual or catalog.
Refer to the following section for information on wiring a single-phase AC power supply
input to the SERVOPACK.

6.4 Automatic Detection of Connected Motor
You can use a SERVOPACK to operate either a Rotary Servomotor or a Linear Servo-
motor.
If you connect the Servomotor encoder to the CN2 connector on the SERVOPACK, the
SERVOPACK will automatically determine which type of Servomotor is connected. There-
fore, you normally do not need to specify the Servomotor type.
