Chapter 2 Plan and Install the Kinetix 5100 Drive System
Transformer Selection
The Kinetix 5100 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, see Circuit Breaker/Fuse
Selection on page 33 and Kinetix Servo Drives Specifications Technical Data,
publication KNX-TD003
.
Passive Shunt Considerations
See Table 8 for the 2198-Exxxx-ERS servo drives that include internal shunt
resistors. Bulletin 2198-Rxxx and 2097-Rx external passive shunts are available
to provide additional shunt capacity for applications where the internal shunt
capacity is exceeded or in applications requiring shunt capacity for drives
without an internal shunt.
IMPORTANT
Transformers (auto transformer is not supported) must have WYE
secondary with grounded neutral. Phase to neutral voltage must not
exceed the input voltage rating of the drive.
IMPORTANT
Use a factor of 1.5 for single and three-phase power (this factor is used
to compensate for transformer, drive, and motor losses, and to account
for utilization in the intermittent operating area of the torque speed
curve).
For example, size a transformer to the voltage requirements of catalog
number 2198-E2030-ERS = 3 kW continuous x 1.5 = 4.5 KVA transformer.
IMPORTANT
A line reactor must be used if the source transformer is greater than 150
KVA, max and 3% impedance, min.
