Chapter 2 Plan the Kinetix 5500 Drive System Installation
Transformer Selection
The servo drive does not require an isolation transformer for three-phase
input power. However, a transformer can be required to match the voltage
requirements of the drive to the available service.
To size a transformer for the main AC power inputs, refer to the Kinetix 5700,
5500, 5300, and 5100 Servo Drives Specifications Technical Data, publication
KNX-TD003
.
Circuit Breaker/Fuse Selection
The Kinetix 5500 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) and 65,000 A (circuit
breakers).
For the wiring diagram, refer to Power Wiring Examples on page 180
.
Standalone Drive Systems
IMPORTANT When using an autotransformer, make sure that the phase to neutral/
ground voltage does not exceed the input voltage ratings of the drive.
IMPORTANT Use a form factor of 1.5 for three-phase power (where form factor is
used to compensate for transformer, drive module, and motor losses,
and to account for utilization in the intermittent operating area of the
torque speed curve).
IMPORTANT A line reactor must be used if the source transformer is greater than
150 KVA, maximum and 3% impedance, minimum
EXAMPLE Sizing a transformer to the voltage requirements of this drive:
2198-H040-ERSx = 8.4 kW = 12.6 KVA transformer.
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 drive’s PWM
waveform does not allow it to operate properly. As a result, damage to the
device occurs.
