Product Dimensions：If you are using the Rockwell Automation/
Allen-Bradley system sizing program, the average
speed and average torque data has already been
calculated and can be used in the above equation. If
you are not sure of the exact speed and torque in
your application, another approach is to look at the
speed/torque curve for your Ultra3000/motor
combination and use the values for the worst case
continuous speed and torque.
Calculations are multiplied by a factor to compensate
for the power and loss elements within a power
system. A factor of 2.0 is used with a single phase
system and a factor of 1.5 is used with a three phase
system. This factor should minimize the effects of the
secondary line voltage sagging in the transformer
during peak current periods.
In the United States, the National Electric Code (NEC) specifies that
fuses must be selected based on the motor full load amperage (FLA).
The typical fuse size should be 300% of the motor FLA for non-time
delay fuses (and time-delay class CC fuses) or 175% of motor FLA for
time delay fuses. If these ratings are not high enough for starting
currents, the NEC allows non-time delay fuses (and time-delay class
CC fuses) to be sized up to 400% of the motor FLA and time-delay
fuses to be sized up to 225% of the motor FLA.
In most cases, fuses selected to match the drive input current rating
will meet the NEC requirements and provide the full drive capabilities.
Dual element, time delay (slow acting) fuses should be used to avoid
nuisance trips during the inrush current of power initialization. Refer
to the section Ultra3000 Power Specifications in Appendix A for input
current and inrush current specifications.
The Ultra3000 utilizes solid state motor short circuit protection rated as
shown in the table below.
Wiring to the auxiliary power terminals (L1 AUX and L2/N AUX) of
the drive should be 2.5 mm2
(14 AWG) minimum and fusing for the
auxiliary power should be selected to properly protect the wire. For
example, if 60° C (140° F) wire is used, the fuse should not exceed
8A. If 75° C (167° F) wire is used, the fuse should not exceed 13A.
Refer to Fuse Specifications in Appendix A for fuse examples.
