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.
