Introductory information about spindle applications

The configurations for spindle applications typically control milling machines with asynchronous ma-

chine (ASM) or permanent magnet synchronous machine (PMSM)

Operation is without encoder at high speeds. In order to enable finer setting of the speed controller

when tools with large diameters are used, using an encoder is possible. When an encoder is used, the

axle can be positioned for tool replacement.

For safe operation in the field weakening range, PMSM, require a brake chopper.

In the field weakening operation will be checked automatically if a brake chopper is available. It`s de-

tected only an existing brake chopper, but not the necessary dimensioning.

This must be performed by the user.

3.1

For spindle applications, the following configurations are available:

− 804: Spindle application with field-oriented speed control of asynchronous machine (ASM)

− 806: Spindle application with field-oriented speed control of permanent magnet synchronous ma-

chine (PMSM)

Configurations 804 and 806 are based on Configurations 410 (sensor-less field-oriented

control of asynchronous machine) and 610 (sensor-less field-oriented control of a syn-

chronous machine, speed controlled).

This application manual describes the changes compared to the underlying configura-

tions. For more information on Configurations 410 and 610, please refer to the Operat-

ing Instructions of the ACU series of frequency inverters.
