Yaskawa Sigma-II Large Capacity - Manual (Page 5)

1-1. Check List when replacing ∑-II with ∑-V
Category Item Items to be Checked Checked
・Please confirm installation dimensions of the motor and machine
in-use.
Pilot diameter
Mounting hole pitch
Mounting hole diameter
Axis diameter
Axis shape (straight, key, center tap, and taper)
Main Body
・Please confirm whether the motor you are using is a special type.
Please confirm the specification with the delivery specifications if
you are using a special type.
Voltage
・Both servo motor and servo amplifier were 100V version when using
the AC100V power supply in ∑-II. However, only AC200V motors
are available in the ∑-V. Select the proper 200V motor when using
AC100V power supply servo amplifier

Cable
・Please confirm cable wiring, and also confirm that the machine has
no interference.
・Please confirm the size (W･H･D) and the mounting hole position of
the servo amplifier in-use.
Main Body
・Please confirm whether the servo amplifier in-use does not have
your own NP, and product shape, and also confirm that any special
processes etc. by referring to the delivery specifications.
・The main circuit connector, terminal block position, array order, and
dividing method are different between the servo amplifier in-use
and the replacement servo amplifier.
Please consider the substitution or extension of wiring when there
is no enough room in wiring.
