Power supply selecting criteria
1.
The power supply module must be capable of supplying the power required by the set of motors
and drives connected to it.
NOTE.
If the power required by the set is greater than 80 kW, the set of motors and drives must be
divided into groups and powered by different power supplies.
MANDATORY.
Note that FM9 spindle motors whose sales models are FM9-B055-
C5C
-E01-A and FM9-B071-C5C
-E01 will necessarily be associated with RPS-75
and RPS-80 power supplies respectively.
T. H5/10
First criteria for selecting the power supply for the whole system.
DANGER.
Never connect the power supplies in parallel!

Until reaching the rated power demanded from the power supply. All the
required power cannot be supplied, hence 2 power supplies will be needed.
NOTE.
When using two power supplies on the same machine, they must make up two
independent groups with their own drives. Only the SERCOS ring or CAN bus (if there is one)
may be common to both groups.
