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 2198-UM005
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. Table 12
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.
