Introduction

This installation guide describes the Bassoon servo drive and the steps for its wiring, installation
and powering up. Following these guidelines ensures maximum functionality of the drive and
the system to which it is connected.

2.1. Drive Description

The Bassoon is a powerful servo drive that operates in digital current, velocity, position and
advanced position modes, in conjunction with a permanent-magnet synchronous brushless
motor or DC brush motor. The Bassoon features flexible sinusoidal and trapezoidal
commutation, with vector control. The Bassoon can operate as a stand-alone device or as part
of a multi-axis network in a distributed configuration.

The Bassoon drive is set up and tuned using Elmo’s Composer software. This Windows-based
application enables users to quickly and simply configure the servo drive for optimal use with
their motor.

The Bassoon connects directly to 110/230 VAC single-phase power source. A separate 24 VDC
power supply serves as both the auxiliary supply and the backup supply. This allows a safe and
economical "power backup" feature that is essential for positioning systems.

Two variations of the Bassoon are available: the Standard version and the Advanced version,
which features advanced positioning capabilities. Both versions operate with
RS-232 and/or CAN communications.
