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 controller to the available service.
To size a transformer for the main AC power inputs, see Circuit Breaker/Fuse
Selection on page 23 and Kinetix Servo Drives Specifications Technical Data,
publication KNX-TD003
.
Passive Shunt Considerations
See Tabl e 8 for the 2198-Exxxx-ERS servo drives that include an internal IGBT
and resistor for shunt purposes. 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 and in applications requiring shunt
capacity for drives without an internal shunt.
Table 8 - External Passive-shunt Options
IMPORTANT Transformer (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 form factor of 1.5 for single and three-phase power (where form 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.
