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

1-1. Check List when replacing ∑-II with ∑-V
Category Item Items to be Checked Checked
<Confirmation of main body installation dimension/position>
・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
<Confirmation of special specification>
・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 <Correspondence of AC100V specification>
・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
Motor
Cable <Confirmation of wiring >
・Please confirm cable wiring, and also confirm that the machine has
no interference.
<Confirmation of main body mounting position>
・Please confirm the size (W･H･D) and the mounting hole position of
the servo amplifier in-use.
Main Body
<Confirmation of special specifications>
・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.
<Confirmation of wiring>
・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.

<AC100V specification>
・Corresponds with the voltage specification "F" (Input 100V, Output
200V. Double voltage) servo amplifier. The servo motors are
AC200V.
