Chapter 2 Servo Drive and System Comparisons
The Kinetix 5300 servo drives use internal solid-state motor short-circuit
protection and, when protected by suitable branch circuit protection, are rated
for use on a circuit capable of delivering up to 200,000 A (fuses, UL
applications), 10,000 A (miniature circuit breakers), or 65,000 A (molded-case
circuit breakers).
See the Kinetix 5300 Servo Drives User Manual, publication
for
the wiring diagrams.
Make sure that the selected components are properly coordinated and meet
acceptable codes including any requirements for branch circuit protection.
Evaluation of the short-circuit available current is critical and must be kept
below the short-circuit current rating of the circuit breaker.
Ultra3000 Servo Drive Main Input Power Fuse and Circuit Breaker Specifications
The Ultra3000 could have used class CC, G, J, L, R, or T class fuses, with current
ratings as indicated in the table.
lists fuse examples that are
recommended for use with the Ultra3000 (230V and 460V) drives.
ATTENTION:
Do not use circuit protection devices on the output of an AC
drive as an isolating disconnect switch or motor overload device. These
devices are designed to operate on sine-wave voltage and the drives PWM
waveform does not allow it to operate properly. As a result, damage to the
device occurs.
