Induction Motor Support

This appendix provides induction motor feature descriptions supported by
Kinetix 5500 servo drives.

Induction Motor Control
Methods

The Kinetix 5500 servo drives support two open-loop frequency control
methods. These are the choices:

• Basic Volts/Hertz - This method is used in single or multi-motor

asynchronous motor applications.

• Sensorless Vector with Slip Compensation - This method is used for

most constant torque applications. Provides excellent starting,
acceleration, and running torque.

To configure your induction motor in the Logix Designer application, refer to

Configure Induction Motor Axis Properties

on

page 127

.

Open-loop frequency control is suitable in applications such as conveyors,
pumps, and fans. These are the features:

Start Boost, Run Boost, and Auto Boost
Electronic motor thermal overload protection per NEC/NEMA Class 10

requirements

Single skip frequency, in which the drive does not operate
All three-phase induction motors suitable for variable speed drives (VFD)

operation are supported
