Transformer Selection
The IAM power module does not require an isolation transformer for three-
phase input power. However, a transformer may be required to match the voltage
requirements of the controller to the available service.
To size a transformer for the main AC power inputs, refer to the Kinetix 6200/
6500 power specifications in the Kinetix Servo Drives Technical Data,
publicatio
For example, to size a transformer to the voltage requirements of a
2094-BC01-M01-M integrated axis module:
2094-BC01-M01-M = 6 kW continuous x 1.5 = 9.0 KVA transformer
IMPORTANT
If using an autotransformer, make sure that the phase to neutral/ground
voltages do 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).
