Chapter 2: 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 CANopen communications.
