Alspa md 2000 manual

Note: It is not possible to produce software to run perfectly on all types of PCs. Data, illustrations, revisions Data and illustrations are not final and binding. They may be subject to change without notice for reasons of technical improvement.

If you have any suggestions concerning this documentation please do not hesitate to contact us. You may use the printed form on Page A for your comments. Without prior permission this document may not be duplicated or in any other way be made available to third parties. It may also not be misused in any way by the recipient or third parties. Translation into a foreign language is not permitted. All data, dimensions, weights, illustrations and other technical data may be subject to change without notice, in particular for the further enhancement of our products.

The details agreed and confirmed for each order will be final and binding. Read this operating manual carefully and thoroughly. Start with the section on installation and only then continue through to commissioning. They will also help to ensure optimum operation of the equipment. Written permission is required before this document may be made available to other parties, duplicated, translated, microfilmed and stored or processed in electronic systems.

Installation, commissioning or maintenance of the ALSPA MD frequency inverter must only be carried out by specialized personnel familiar with the equipment and machinery involved. Serious injury or damage to the equipment may result when these instructions are ignored. Work on the equipment is only permitted when completely powered down.

The drive motor is to be connected to a suitable protective conductor. Failure to do so may result in electric shock. Any data, dimensions, weights, illustrations and other technical information shall be subject to change without notice, particularly in the interest of further perfecting our equipment. The data and specifications agreed to in the event of an order shall be generally deemed as being the binding basis.

The power stack consists of a diode rectifier in a 3-phase bridge circuit on the mains side and an IGBT inverter on the motor side. The basic inverter models are designed for standard applications.

Through suitable options eg. Operation of all units is identical throughout the entire type range. Easy familiarisation and operation as well as maximum flexibility were the prime objectives during development. The inverters are operated and parameters adjusted by means of a optional removable control unit BDE or using a PC and an PC software package.

Connection to automation systems is possible through conventional bus systems see field bus coupler options. With a mains voltage range from to V build-in units cover the power range from 22 kVA to kVA. In conjunction with standard asynchronous motors the drive capacities provided are therefore as follows: - At unit rated current A 3- phase choke connected to the mains supply reduces harmonic currents and serves to decouple the unit from other converters consumers on the same supply network.

The link voltage is smoothed by high quality electrolytic capacitors. With the motor converter these provide the magnetising reactive power required by the motor and decouple the converter on the mains side from the inverter on the motor side. Through optimised pulse width modulation the motor converter generates from the link voltage a sinusoidal 3-phase system with variable frequency and voltage. A power dump option in conjunction with a braking resistor allows braking energy to be used in regenerative operation.

Different control structures such as, frequency control, speed control with or without encoder and torque control with or without encoder can be selected, depending on the application requirements. The field-orientated control concept provides control dynamics directly comparable to those of a DC drive.

In addition, various inputs and outputs can be connected individually according to the task involved. The recipient hereof or any third party shall not use this document for any improper purpose whatsoever. Translation to any foreign language is not permitted.

Through optimised pulse width modulation the motor converter generates from the link voltage a sinusoidal 3-phase system with variable frequency and voltage. Electrical equipment represents a source of risk. The units described here carry dangerous voltages and control rotating mechanical parts.

Death, severe physical injury and extensive material damage may result if these instructions are not followed. Dangerous voltages of over V which can cause death or severe physical injury can occur during operation of these units. Extreme caution is essential when working on the unit.

Please therefore note the following warnings. Covers must remain installed during normal operation. The conditions of VBG4 paragraph 22 must be observed for adjustment work during operation with the unit open. Stand on an insulated mat compliant with EGB and ensure it is not earthed if you are carrying out commissioning work when the unit is switched on. Do not use any technical equipment unless you are certain it is in perfect condition and undamaged. If an oscilloscope is used, it must be powered through an isolating transformer to prevent earth loops.
