Table 13-5 Maximum motor rated current
Up to 10 SPMAXXXX or SPMDXXXX drive modules can be connected
in parallel to make a larger drive, provided all power modules are of the
same type, and have the same voltage and current ratings. The currents
are then defined as follows:
Current scaling (K
c
)
K
c
is the sum of K
c
for all the modules.
Maximum Heavy Duty current rating
Maximum Heavy Duty current rating = 0.95 x the sum of maximum
Heavy Duty current rating for all the modules.
Maximum Normal Duty rated current
Maximum Normal Duty rated current = 0.95 x the sum of maximum
Normal Duty rated current for all the modules.
