2.
The main power supply must be capable of supplying the peak power required by the set of drives
connected to it
.
3. The range of FAGOR main power supplies that can be selected is:
T. H5/19
Second selection criterion for the main power supply of the system.
T. H5/20
Power supplies of the FAGOR catalog. They indicate: Rated power at 400 V AC, permitted range
of line voltages and if a 24 V DC auxiliary power supply is integrated or not.
SECOND CRITERIA
The main power supply must be capable of supplying the peak power required (depending on the duty cycles)
by all the motor-drive combinations connected to it.

- Refer to note below -
If the required peak power (calculated B value) exceeds 175 kW, then install a second main power supply.
Divide the set of drives into two groups so they can be powered by different power supplies. Refer to the
IMPORTANT NOTE
below.
IMPORTANT NOTE.
When using two main power supplies on the same machine, these must make up
two
independent groups
with their own drives. Only the SERCOS-III BUS can be common for both
groups.
DANGER.
NEVER
connect the DC BUSES of the main power supplies in parallel.
ALWAYS
install the two groups separately.
