Chapter 2: Product Description
This installation guide describes the Flute servo drive and the steps for its wiring, installation
and power-up. Following these guidelines ensures optimal performance of the drive and the
system to which it is connected.
2.1. Drive Description
The Flute series of miniature servo amplifiers is designed for brushless motors in which
sinusoidal commutation is performed by the motion controller. The amplifier accepts two
current commands from the motion controller and internally processes the third phase current
requirement to produce a balanced three-phase configuration. The basic configuration is a
current mode amplifier targeting the OEM market. As such, it has no trimmers and is installed
directly on the customer’s PCB like any other component. The Flute amplifier meets UL508c
and the relevant CE regulations.
The Flute power stage is implemented on a single ceramic substrate. This design enables very
high thermal conductivity, high current carrying capacity, improved EMC and good mechanical
strength. The control section is implemented by dedicated custom ICs that contribute to higher
reliability resulting from fewer components, and enhanced performance due to the amplifier
integration.
