Transformer Selection
The integrated axis module (IAM) 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 Circuit
Breaker/Fuse Specifications on page 177 and Transformer
Specifications for Control Power Input on page 179.
Example: Sizing a transformer to the voltage requirements of a
2094-AC05-M01 Integrated Axis Module:
2094-AC05-M01 = 3 kW continuous x 1.5 = 4.5 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).
