INTRODUCTION ...............................................................

GENERAL

These are the Operating Instructions for

the MICROMASTER Eco and

MIDIMASTER Eco and are to be used

for quick and simple commissioning

only.

For more details and the complete

parameter list for specific

applications consult the Eco

Reference Manual on our website

(details available on back page).

The Eco range of inverters comprises

variable frequency inverters for

controlling the speed of fans and pump

motors. The Eco can also be

programmed to manage many other

motor functions and limits. These

functions are set by parameters which

are programmed using the keypad.

TYPES OF SYSTEM CONTROL

The MICROMASTER and MIDIMASTER

Eco inverters are normally controlled

using the keypad or input/output

terminals. However, there is an option

for remote operation using the RS485 D-

type connection on the front panel, see

the Eco Reference Manual for further

details.

The output frequency and hence the

motor speed can be controlled by digital

or analog inputs. The digital inputs can

be programmed to control the motor

speed by means of:

· frequency set points,

using the keys

· fixed frequencies, via binary inputs

· motorized potentiometer function

The analog inputs can be programmed

for voltage or current input in conjunction

with DIP selector switches.

Closed loop process control, using a

standard Proportional, Integral,

Derivative (PID) control loop function

can be selected. This control is set-up

using DIP selector switches and analog

input 2. A 15V, 50 mA supply is

provided to power the feedback

transducer.

MECHANICAL INSTALLATION .......................................

MOUNTING

The IP20/21 range of Eco units can be

mounted side-by-side without space in

between. A clearance distance of at least

100mm top and 160 mm bottom must be left

free for the movement of cooling air.

IP56 Eco units must have a clearance

distance of at least 150mm in all directions.

A good bonding between the Eco and the

metal back plate is necessary to ensure good

grounding and low RF (radio frequency)

impedance. If necessary remove some back

plate paint and/or use toothed washers to

ensure safety and EMC (electro-magnetic

compatibility). Use an earth braid on 400V

ratings 1.5KW and below.

Ambient temperature

MICROMASTER Eco 0oC to 50oC.

MIDIMASTER Eco (IP20/21/56) 0oC to 40oC.

Ensure that the Eco is not subject to shock,

vibration or atmospheric pollutants.

MOTOR CABLES

To minimise the effects of radio frequency

emissions:-

· Screened cables should be used between

the Eco and the motor.

· Keep cables to motor as short as possible,

generally under 25m.

· Terminate cable screens correctly (use

gland fittings which give 360 deg.

conduction) on both the Eco gland plate and

the motor terminal box.

· Fit suppressors on all contactor coils.

· If an external input EMC filter is to be fitted

then ensure that it is positioned as close as

possible to the Eco and is well grounded to

the metal back plate. Use screened cable

between the external input EMC filter and

the Eco input terminals, and ground cable

screen correctly.

All MICRO/MIDIMASTER Eco products

comply with the requirements of the EMC

Directive when installed in accordance with the

wiring recommendations of this manual. The

units comply with European Norm EN61800-3

“Adjustable speed electrical power drive

systems”. This standard specifies different

limits for domestic and industrial applications,

which defines whether an integral EMC filter is

required. For further information refer to the

Eco Reference Manual.

When units are selected which include integral

filters they will meet the conducted and

radiated RF emissions limits specified in EN

55011.

CONTROL AND SERIAL

COMMUNICATION CABLES

To minimise the effects of radio frequency

emissions and interference:-

· Screened control and data cables should be

used with the Eco.

· Terminate the control and data cable

screens correctly on the Eco by using the

gland plate and/or clamps provided.

Consult the instructions for the Building

Management System or controller at the

opposite cable end.

· IT IS MOST IMPORTANT THAT THE

MOTOR AND CONTROL CABLES ARE

KEPT APART. IF CONTROL AND

POWER CABLES NEED TO CROSS,

ARRANGE THE CABLES SO THAT THEY

CROSS AT 90° IF POSSIBLE.

CIRCULATING CURRENTS

If there is a slight difference between the

chassis potential of the Eco and the Building

Management System (or controller) then

circulating currents can occur in the control or

data cable screens.

These circulating currents should be avoided

by separately connecting the chassis of both

pieces of equipment securely to the same

earthing point.

THE KEYPAD

The keypad comprises membrane-type keys

as well as an integral 4-digit 7-segment LED

display. The keys are limited to [run], [stop],

[up], [down] and [P]. All parameters can be

accessed and changed using the keys.

PARAMETER TYPES

There are three types of parameter:

1 True value parameters. For example,

setting parameter P003 to 10 seconds tells

the Eco to take 10 seconds to slow the

motor from its normal operating speed to

stopped (ramp-down time).

2 Limited range parameters. The values

themselves are not relevant and only

represent the function required. For example,

parameter P199 can only be set to 0 to 1.

Setting the value to 0 tells the Eco to give

access to the basic parameters only. Setting

the value to 1 gives access to the expert

parameters.

3 ‘Read only’ parameters. The values of

these parameters are factory set and

provide the user with information. For

instance, parameter P111 is a read only

parameter and indicates the inverter’s

variable torque power rating in kW.

PARAMETER RANGES

The Eco has three ranges of parameters;

Display mode, Basic mode and Expert mode.

One of the Basic mode parameters (P199)

controls access to the Expert mode

parameters. The Basic mode parameters are

described in this section. A list of the Expert

mode parameters is contained in the next

section. For further information on using

Expert mode, refer to the Reference Manual

(G85139-H1750-U630).

ACCESSING PARAMETERS

AND CHANGING VALUES

The and keys are used to change

parameter values. The keys have two modes

of operation. A single momentary press will

change the value by a value of 1. Keeping the

button pressed for longer initiates scrolling and

allows values to be changed rapidly.

To access a parameter and change its value,

follow the simple sequence described below:

Key Action Display

Press P to enter parameter

mode

Use the [up] and [down] keys to

select the required parameter

number (e.g. ramp-up time)

Press P to confirm that you

wish to enter a value for that

parameter. The current value

is displayed

Use the [up] and [down] keys

to enter the required value

Press P to confirm that you

have changed the value as

required. The parameter

number is re-displayed.

Use the [up] and [down] keys

to return the parameter

number to the display default

parameter.

Press P to return to default display

The display will alternate between the setpoint

frequency and actual output frequency, which

will be 0 Hz.

DISPLAY MODE PARAMETERS......................................

Parameter Function Range Default Units

P000 Operating display -(output frequency) Hz

Displays the output selected by P001 (an Expert mode parameter).

Display selection via P001:

0 = Output frequency (Hz) 4 = Motor torque (% nominal)

1 = Frequency setpoint (i.e. speed at 5 = Motor speed (rpm)

which inverter is set to run) (Hz) 6 = USS serial bus status (Code)

2 = Motor current (A) 7 = PID Feedback signal (%)

3 = DC-link voltage (V) 8 = Output voltage (V)

The default setting (0) displays the inverter output frequency. If the inverter is in stand-by mode, the

flashing display will alternate between the setpoint frequency and actual output frequency, which will

be 0 Hz when not being run.

In the event of a failure, the relevant fault code (Fnnn) is displayed.

BASIC MODE PARAMETERS………………………………

Parameter Function Range Default Units

P002 Ramp-up time 0 - 650.0 20 Seconds

This is the time taken for the motor to accelerate from standstill to the maximum frequency. The

maximum frequency is set by parameter P013. Setting the ramp-up time too short can cause the

inverter to trip (Fault code F002 = overcurrent).

P003 Ramp-down time 0 - 650.0 20 Seconds

This is the time taken for the motor to decelerate from maximum frequency to standstill. The

maximum frequency is set by parameter P013. Setting the ramp-down time too short can cause the

inverter to trip (Fault code F001 = DC link overvoltage). This is also the period for which injection

braking is applied, if selected (refer to parameter P073 in Expert mode).

P003 Frequency setpoint

source selection

0 – 2 0 -

The value of this parameter (0, 1 or 2) selects the mode of control of the inverter’s frequency

setpoint.

0 = digital motorised potentiometer. The inverter runs at the frequency set in P005 (refer

to Expert mode) and can be controlled with the [up] and [down] keys. If P007 (see below)

is set to 0, the frequency can be increased or decreased by setting any two of the digital

inputs (P051 to P055 or P356 - refer to Expert mode) to the values of 11 and 12.

1 = Analog. The inverter output frequency is controlled by analog input signals (0-10V,

0/4-20mA or potentiometer).

2 = Fixed frequency. Fixed frequency is only selected by setting the value of at least one

of the digital inputs (P051 to P055 or P536 - refer to Expert mode) to the value of 6 or 7.

Description/Notes

P071 Slip

compensation

(%)

0-200

[90]

The inverter can estimate the amount of slip in an

asynchronous motor at varying loads and increase its

output frequency to compensate for this. This

parameter ‘fine tunes’ the compensation for different

motors in the range 0 - 200% of the calculated slip.

WARNING: This parameter must be set to zero

when using synchronous motors or motors that

are connected in parallel. This is because over-

compensation can cause instability.

P073 DC injection

braking (%)

0-200

[0]

Range is

variant

dependent

This rapidly stops the motor by applying a DC braking

current and holds the shaft stationary until the end of

the braking period.

Additional heat is generated within the motor.

Braking is effective for a period of time set by P003.

The DC brake can be activated using DIN 1 to DIN 6

(see P051 to P055 and P356).

WARNING: Frequent use of long periods of DC

injection braking can cause the motor to overheat.

If DC injection braking is enabled via a digital

input then DC current is applied for as long as the

digital input is high. This causes heating of the

motor.

P076 Pulse frequency 0-7

[0]

Sets the pulse frequency (from 2 to 16 kHz) and PWM

mode. If silent operation is not absolutely necessary,

the losses in the inverter as well as the RFI emissions

can be reduced by selecting lower pulse frequencies.

0/1 = 16 kHz

2/3 = 8 kHz

4/5 = 4 kHz (400 V default)

6/7 = 2 kHz

The default switching frequency FS8 and FS9

(110 kW to 315 kW) is set to 2 kHz.

Even numbers = normal modulation technique.

Odd numbers = lower loss modulation technique used

when operating mainly at speeds above 5 Hz.

Note: Selecting 8KHz or 16KHz may reduce the

output current rating.

P077 Control mode 0 to 6

[0]

0 = Multi-motor mode

4 = Energy saving mode

5 = Linear V/f characteristic with variable torque

6 = Square V/f (Fan and Pump characteristic)

[50]

ensure consistent starting and to overcome

stiction effects

P080* Nominal rating

plate motor

power factor

0,00 -1,00

(cos.j)

If efficiency is shown on the motor rating plate,

calculate the power factor as follows: pf =

. hp x 746 .

1.732 x efficiency x nom. volts x nom. amps

P086 Motor current

limit (%)

0-200

[100]

Defines the motor overload current as a % of the

nominal motor current (P083) allowed for up to one

minute.

With this parameter, the motor current can be limited

and overheating of the motor prevented. If this set

value is exceeded for one minute; the output

frequency is reduced until the current falls to that set

in P083. The inverter can be made to trip by using

the relay in conjunction with P074.

Note: The maximum value that P086 can be set to is

automatically limited by the rating of the inverter.

P088 Automatic

calibration

0 - 1

[1]

When P088 is set to ‘1’ and the RUN button is

pressed, the inverter automatically measures the

stator resistance; stores it in P089 and then resets

P088 to ‘0’.

This calibration has to be carried out each time the

motor is changed.
