Yaskawa Sigma-II Large Capacity - Manual (Page 6)

・Three-phase circuit AC200V is standard In the ∑-V series servo
amplifier.
Please change the parameter "Function selection switch B" when
using single-phase power supply. (Pn00B.2=1)
(Contents are the same as the motor voltage specifications)
Connect to terminal L1 and L2 when using the single-phase power
supply.
Please note that the torque-speed characteristic is different from
the three-phase circuit power supply specifications.
Also please note that the size of 1.5kW single-phase AC200V servo
amplifier (SGDV-120A A008000) is the same as the 3kW
three-phase AC200V specification (SGDV-200A A).
・Please change the parameter "Function selection switch 1" when
using DC power supply input. (Pn001.2=1)
Note) Connect the main circuit DC power supply only after
changing the parameter.
Control
Circuit ・ The control circuit connector, numbers of pins, array order might
be different between the servo amplifier in-use and the
replacement servo amplifier.
Software
・ Confirm whether the software of the servo amplifier in-use is
standard software from the version number. Contact Yaskawa
with the version number if you are not sure the software is
standard or not.
Software version can be confirmed with the handheld digital
operator, or function Fn012 of built-in panel operator, and product
data reading function of the supporting software SigmaWin+.
Servo
Amplifier
Software
Constant < Confirmation of user constants >
・Confirm the user constants of the servo amplifier in-use.
SigmaWin + has a function to convert from the user constants of
∑-II into the parameter of ∑- V.
・Factory default setting of ∑-V servo adjustment parameter is “enable
tuneless” (Pn170.0=1). Change it to “disable tuneless”
(Pn170.0=0) when you perform the servo adjustment.
