1. If devices EVx9321  EVx9333 or 8200 vector are used in the drive
system:
Look for the rated powers of the connected motors in the table and write
down the corresponding powers P
DC
.
2. If devices ECSxAxxxC4B are used in the drive system:
Look for the connected axis modules in the table and write down the
corresponding powers P
DC
.
3. If required, determine the power P
DC
additionally available for the
devices EVx9335  EVx9338, EVx9381  EVx9383 in the drive system
by means of a rough estimate:
Device power ˘ rated power of the motor connected
4. Add all powers P
DC
from steps 1. and 2. and subtract the power P
DC
that is additionally available.
– The result is the input power required.
5. Select the 9360 DC power supply units to provide the input power.
