Both types of inverter are microprocessor–controlled. A special pulse–width modulation method with selectable pulse frequency permits extremely quiet motor operation. Complete inverter and motor protection is provided by various protective functions.

Features

• Microprocessor–control for reliability and flexibility.

• Remote control capability via RS485 serial link using the USS protocol.

• Ability to control up to 31 inverters via the USS protocol.

• A comprehensive range of parameters is provided to enable the inverters to be configured for use in almost any

application.

• Built–in non–volatile memory for storing parameter settings.

• Factory default parameter settings pre–programmed for European and North American requirements.

• Output frequency (and hence motor speed) can be controlled by one of five methods:

(1) Digital frequency setpoint (2) Analogue setpoint (voltage or current input) (3) Motor potentiometer (4) Fixed frequency (5) Via remote data transmission

• Built–in dc injection brake.

• Built–in brake chopper for external resistor (MICRO MASTER), optional for MIDI MASTER.

• Integral RFI filter on MM25 – MM220.

• Automatic load compensation by flux current control.

• Built–in ramp generator for variable ramping times.

• Membrane–type front panel controls.

• Two relay outputs incorporated.

• Analogue output incorporated.

• External connection for optional enhanced operator panel or for use as external RS485 interface.

• Closed loop control using a standard Proportional, Integral, Derivative (PID) control loop function.

• Optional protection to IP54 (minimum) for MIDI MASTER inverters.

. V arious models are available, ranging from the compact 250 W MICRO MASTER up to the 37 kW

(see section 1.3 below)

Operating Instructions

2. INSTALLATION

WARNING

THIS EQUIPMENT MUST BE EARTHED. T o guarantee the safe operation of the equipment it must be installed and commissioned properly by

qualified personnel in compliance with the warnings laid down in these operating instructions. T ake particular note of the general and regional installation and safety regulations regarding work on

high voltage installations (e.g. VDE), as well as the relevant regulations regarding the correct use of tools and personal protective gear.

Make sure that the unobstructed clearance for each of the cooling inlets and outlets above and below the inverter is at least 100 mm (200 mm on all sides for IP54 variants).

Ensure that the temperature does not exceed the specified level when the inverter is installed in a cubicle.

Avoid excessive vibration and shaking of the equipment. Inverter models MM25 and MM25/2, MM37 and MM37/2, MM55 and MM55/2, and MM75 and

MM75/2 must be fixed securely to a flat surface before use to prevent access to the capacitors contained within the heatsink.

Note: Consider the possible use of options (e.g. RFI suppression filters) at the planning stage.

2.1 Wiring Guidelines to Minimise the Effects of EMI

The inverters are designed to operate in an industrial environment where a high level of Electro–Magnetic Interference (EMI) can be expected. Usually, good installation practices will ensure safe and trouble–free operation. However, if problems are encountered, the following guidelines may prove useful. In particular, grounding of the system 0V at the inverter, as described below , may prove effective. Figure 2 illustrates how an RFI suppression filter should be installed.

(1) Ensure that all equipment in the cubicle is well earthed using short, thick earthing cable connected to a

common star point or busbar. It is particularly important that any control equipment that is connected to the inverter (such as a PLC) is connected to the same earth or star point as the inverter via a short, thick link. Flat conductors (e.g. metal brackets) are preferred as they have lower impedance at high frequencies.

The return earth from motors controlled by the inverters should be connected directly to the earth connection (PE) on the associated inverter.

(2) Use saw–tooth washers when mounting the inverter and ensure that a good electrical connection is made

between the heatsink and the panel, removing paint if necessary.

(3) Wherever possible, use screened leads for connections to the control circuitry . T erminate the ends of the cable

neatly, ensuring that unscreened wires are not left visible.

(4) Separate the control cables from the power connections as much as possible, using separate trunking, etc. If

control and power cables cross, arrange the cables so that they cross at 90

(5) Ensure that contactors in the cubicle are suppressed, either with R–C suppressors for AC contactors or

‘flywheel’ diodes for DC contactors, fitted to the coils. Varistor suppressors are also effective. This is particularly important if the contactors are controlled from the relays on the inverter.

if possible.

(6) Use screened or armoured cables for the power connections and ground the screen at both ends via the cable

glands.

(7) If the drive is to be operated in a noise–sensitive environment, the RFI filter kit should be used to reduce the

conducted and radiated interference from the inverter. In this case, the filter should be mounted as close to the inverter as possible and well grounded inverter.

(8) Select the lowest switching frequency possible. This will reduce the amount of EMI generated by the inverter .

(see (2) above)

and the supplied metallised cover should be fitted to the

On no account must safety regulations be compromised when installing inverters!

Operating Instructions

When attempting to meet specific EMC limits by using a filter, the following points must be observed:

(1) All cables to and from the

inverter (including control cables) must be screened using suitable glands.

(2) The control cable must be kept

separate from the motor and mains cables.

(3) It may be necessary to fit a

screened lid to the inverter.
