1 General Information

1.1 Explanation of Symbols and Notes

Work Safety Symbol

You will find this symbol next to all work safety notes in this operating manual if there is a
risk of injury or death for persons involved. Pay attention to these notes and observe par­ticular caution in such cases. Also pass on all work safety instructions to other users.

Voltage Warning

This symbol is shown wherever particular caution is necessary owing to occurring or ap­plied voltages (e.g. DC voltages up to 650 V) and where special precautionary measures
have to be taken. The inverter must always be isolated from the mains when working on it.

Caution Note

ATTENTION!

This note is shown in all parts of this operating manual to which particular attention must be
paid to ensure that the guidelines, specifications, notes and the correct sequence of work
will be obeyed and to prevent damage or destruction of the inverter and/or systems.

1.2 Safety and Operating Instructions for Drive Converters

1. General

In operation, drive converters, depending on their degree of protection, may have live,
unisolated, and possibly also moving or rotating parts, as well as hot surfaces.

In case of inadmissible removal of the required covers, of improper use, wrong installation
or maloperation, there is the danger of serious personal injury and damage to property.

For further information, see documentation.
All operations serving transport, installation and commissioning as well as maintenance are

to be carried out by skilled technical personnel (Observe IEC 364 or CENELEC HD 384
or DIN VDE 0100 and IEC 664 or DIN/VDE 0110 and national accident prevention rules!).

For the purposes of these basic safety instructions, “skilled technical personnel” means per­sons who are familiar with the installation, mounting, commissioning and operation of the
product and have the qualifications needed for the performance of their functions.

We draw attention to the fact that no liability can be assumed for damage and malfunctions
resulting from failure to observe the operating manual.

Technical amendments of illustrations and data given in this operating manual are reserved
in the interest of improving the unit and its functions.

2. Intended Use

The application of the drive converter described in this operating manual exclusively serves
the purpose of continuously variable speed control of three-phase motors.

Drive converters are components designed for inclusion in electrical installations or machin­ery.

The drive converters are designed for installation in a switchgear cabinet and for permanent
connection.

The operator of the system is solely liable for damage resulting from improper use of the
drive converter.

Berges electronic • D–51709 Marienheide-Rodt • Tel. [phone] • Fax [phone]

Only items expressly approved by BERGES (e.g. mains filter, choke, external braking chop­pers and braking resistors etc.) may be used as accessories.

The installer of the system is liable for any damage resulting from the use of accessories
that have not been approved expressly by BERGES. Please consult us in case of doubt.

In case of installation in machinery, commissioning of the drive converters (i.e. the starting
of normal operation) is prohibited until the machinery has been proved to conform to the
provisions of the directive 89/392/EEC (Machinery Safety Directive – MSD). Account is to
be taken of EN 60204.

Commissioning (i.e. the starting of normal operation) is admissible only where conformity
with the EMC directive (89/336/EEC) has been established.

The drive converters meet the requirements of the low-voltage directive 73/23/EEC. They
are subject to the harmonized standards of the series prEN 50178/DIN VDE 0160 in con­junction with EN 60439-1/DIN VDE 0660, part 500, and EN 60146/DIN VDE 0558.

The technical data as well as information concerning the supply conditions shall be taken
from the rating plate and from the documentation and shall be strictly observed.

3. Transport, Storage

The instructions for transport, storage and proper use shall be complied with.
Damage established after delivery must be notified to the transport company immediately.

Where necessary, the supplier must also be notified before the damaged drive converter is
put into operation.

The climatic conditions shall be in conformity with prEN 50178.

4. Installation

The installation and cooling of the appliances shall be in accordance with the specifications
in the pertinent documentation.

The drive converters shall be protected against excessive strains. In particular, no compo­nents must be bent or isolating distances altered in the course of transportation or handling.
No contact shall be made with electronic components and contacts.

Drive converters contain electrostatic sensitive components which are liable to damage
through improper use. Electric components must not be mechanically damaged or de­stroyed (potential health risks).

5. Electrical Connection

When working on live drive converters, the applicable national accident prevention rules
(e.g. VBG 4) must be complied with.

The electrical installation shall be carried out in accordance with the relevant requirements
(e.g. cross-sectional areas of conductors, fusing, PE connection). For further information,
see documentation.

Instructions for the installation in accordance with EMC requirements, like screening, earth­ing, location of filters and wiring, are contained in the drive converter documentation. They
must always be complied with, also for drive converters bearing a CE marking. Observance
of the limit values required by EMC law is the responsibility of the manufacturer of the in­stallation or machine.

The components of the power section and certain elements of the control section are con­nected to the voltage mains when the drive converter is connected to the mains voltage.

Touching these components involves mortal danger!

Always isolate the drive converter from the mains supply before performing any work on the
electrical or mechanical part of the system.

Isolate the drive converter from the mains before removing the terminal cover or the hous­ing (e.g. by removing or deactivating on-site fuses or by deactivating a master switch iso­lating all poles etc.).

After disconnection of the drive converters from the voltage supply, live appliance parts and
power terminals must not be touched immediately because of possibly energized capaci­tors. In this respect, the corresponding signs and markings on the drive converter must be
respected. After switching off the mains voltage, wait for at least 5 minutes before begin­ning work on or in the drive converter. Dangerous voltages are still present as long as the
“STATUS” lamp is still lit. In the event of malfunctions, the discharge time of 5 minutes may
be exceeded substantially.

The drive converter contains protective facilities that deactivate it in the event of malfunc­tions, whereby the motor is de-energized and comes to a standstill (so-called “coasting” of
the motor is possible depending on the rotating mass of the type of drive involved). Stand­still of the motor can, however, also be produced by mechanical blockage. Voltage fluctua­tions, and particularly mains power failures, may also lead to deactivation. In certain
circumstances, the drive may start up automatically once the cause of the fault has been
remedied. As a result of this, certain systems may be damaged or destroyed and there may
be a risk for operators working on the system. Installations which include drive converters
shall be equipped with additional control and protective devices in accordance with the rel­evant applicable safety requirements, e.g. Act respecting technical equipment, accident
prevention rules etc. Changes to the drive converters by means of the operating software
are admissible.

1.3 Preface

The motor may be stopped during operation by disabling it or by deactivating the setpoint,
whereby the drive converter and motor may remain live. If inadvertent start-up of the mo-

tor must be excluded to protect operating personnel, electronic interlocking by dis­abling the motor or by deactivating the setpoint is inadequate. This is why the drive
converter must be isolated from the mains voltage.

During operation, all covers and doors shall be kept closed.
Measuring instruments must be connected and disconnected only in de-energized condi-

tion.
Unauthorized conversions or modifications on or in the drive converter and its components

and accessories will render all warranty claims void.
Please contact BERGES if conversions or modifications are necessary, particularly if elec-

trical components are involved.

7. Maintenance and Servicing

The manufacturer's documentation shall be followed.

3 Installation

3.1 Inspection

A. Upon receipt, unpack and carefully inspect for any damage sustained in transit (depres-

sion in the enclosure, damage to parts, missing parts).

B. Remove the cover (see page 25) and inspect the inverter for any apparent damage or

foreign objects. Ensure that all mounting hardware and terminal connection hardware is
properly seated, securely fastened, and undamaged.

C. Read the technical data label and ensure that the correct rated output and input voltage

for the application has been purchased.

D. If the inverter is to be stored for a long period of time, repack and store in a clean, dry

place, free from direct sunlight or corrosive fumes, and in a location where the ambient
temperature will not be less then -20 °C nor more than +60 °C.

3.2 General Rules for Installation

Improper installation of the inverter will greatly effect its life. Be sure to observe the following
points when selecting a mounting location. VIOLATING THE CONDITIONS LISTED BE-

LOW MAY VOID THE WARRANTY!

A. Mount the unit vertically and do not restrict the airflow to the heat sink fins on the back

of the controller. The fan and fins allow cooling of internal components. Any air restric­tion could greatly reduce the life of the inverter, as well as resulting in nuisance overtem­perature trips.

B. The ACP inverter generates heat, and therefore there must be a sufficient amount of

free space around the unit (see Figure 3.1). If the unit is accommodated in a housing
together with a different unit, the prescribed minimum distances must be observed so
that adequate ventilation can be ensured.

Figure 3.1

C. If the inverter has to be installed in a different position, external cooling is required for

full capacity utilization. In certain circumstances, the internal air circulation does not suf­fice when installing the unit in a control cabinet with a small volume. Therefore, when
installing the unit, you must ensure that a heat buildup is prevented.

D. Do not mount the ACP near heat generating equipment, or in direct sunlight. BERGES

inverters are generally designed so that they can be operated at ambient temperatures
of 0 °C to +50 °C (IP 00) or 0 °C to 40 °C (IP 21) and at a relative humidity of up to 90%.

The occurrence of condensate must be avoided!

04_GB ACP 3000 — 0.37–15.0

11

Berges electronic • D–51709 Marienheide-Rodt • Tel. [phone] • Fax [phone]

E. Do not install the inverter in a place subjected to high temperature, high humidity, or ex-

cessive vibration (see Table 2.3, “Ambient Conditions”)

F. The units should never be installed in the proximity of corrosive or flammable gases,

conductive dust or large magnetic and electric fields.

G. Pay close attention during installation to ensuring that no objects (such as drilling swarf,

wire or anything else) fall into the unit. Otherwise, a device fault cannot be excluded,
even after longer periods of operation.

ATTENTION!

H. Do not use wire end ferrules for the control terminals. The terminals are designed

so that the wires can be inserted in the terminals after twisting the individual
wires.

I. Table 3.1 shows the watts generated by the inverter when at full current. The heat gen-

erated is dependent on the carrier frequency used. For carrier frequencies other than
those shown in Table 3.1, consult BERGES or use the worst-case scenario (16 kHz car­rier).

3.3.1 Suggestion on how to solve the Problem of Radio Frequency Interference
Suppression of Frequency Converters to VDE 0875/EN 55011

It is necessary to connect a mains filter type “BE/(xxx) xxxx” before every frequency con­verter. The size (xxx) depends on the rated current of the unit. A motor choke can be dis­pensed with.

HINT!

The motor choke type BV... may be necessary as from a cable length in excess of 20 m and
when operating several motors in parallel on one frequency converter output. This choke
attenuates the capacitive earth leakage currents and considerably reduces wire-borne in­terference voltages.

The converter and accessories must be wired in accordance with the following schematic.
To render the remaining interference voltage at the PE conductor potential ineffective for
“external measurement systems”, the following proposed circuit will achieve successful re­sults if applied consistently.

Electrical/electronic devices are capable of influencing or disturbing each other through
connecting cables or other metallic connections. “Electromagnetic compatibility” consists of
the factors “interference resistance” and “interference emission”. Correct installation of

the inverter in conjunction with any possible local interference suppression meas­ures has a crucial effect on minimizing or suppressing mutual interference.

The scope of noise suppression measures depends on the limit value class, the local situ­ation and the application.

The following notes refer to a mains power supply that is not “contaminated” by high fre­quency interference. Other measures may be necessary to reduce or suppress interference
if the mains voltage is “contaminated”. No generally valid recommendations can be given
in such cases. Please consult BERGES if all recommended interference suppression
measures should not produce the desired result.

Basically, it is not the cross section of the conductor that is important for radio-frequency
interference suppression but the surface area. Since the high-frequency interference does
not flow through the entire cross section but mainly on the outer surface of the conductor
(skin effect), braided copper tapes of corresponding cross section should be used.

All conductive housing parts must be interconnected using corresponding lines. Minimum
cross sections are prescribed for a fault case at 50 Hz (referred to the range of the safety
regulations) which must be observed under all circumstances.

The inverter and all other components used for interference suppression (especially also
the shield of the motor cable) should be contacted over as large an area as possible when
connected to metal (control panels, switchgear cabinets and similar) (skin effect). Remove

the paint at the respective areas to ensure good contacting over a large area!

A central earthing point should be used for interference suppression (e.g. equipotential
bonding strip or centrally at an interference suppression filter). The earthing lines are routed
to the respective terminals radially from this point. Conductor loops of the earthing lines
are impermissible and can lead to unnecessary interference.

The shield cross section must not be reduced when the shield is connected to continuing
lines. This would give rise to RF resistance at a cross section reduction, and the resulting
RF energy would consequently not be discharged but radiated. Shields – particularly
shields of control lines – must not be contacted via pin contacts of plug connectors. In these
cases, the metallic hand guard of the plug connector should be used for large-area connec­tion of the shield.

Use a shielded motor cable (earthed over a large area at both sides). The shield should be
routed uninterrupted from the PE terminal of the inverter to the PE terminal of the motor.
If a shielded motor line cannot be used, the unshielded motor line should be laid in a metal
duct. The metal duct must be uninterrupted and adequately earthed. The following points
are prescribed if radio interference suppression is to be realized in accordance with EN
55011, EN 55014 and EN 50081-1:

• Preceding the unit by a mains filter or a mains filter and a output choke (mains filter and
output choke not included in the scope of delivery).

• Laying the motor cable in a shielded configuration.

• Laying the control cable in a shielded configuration.

• Observe general RFI suppression measures (refer to the chapters 3.3.1 and 3.3.4).

Lay motor, mains power and signal cables as far away from each other as possible and sep­arately.

If a mains filter is used, the smallest possible spatial distance from the frequency inverter
must be selected so that both units can be connected by short connection leads.

If an output choke is used (option), it must be fitted in the direct vicinity of the inverter and
connected to the inverter via screened cables earthed at both ends.

16

Shielded signal cables should be laid at a minimum distance of 10 cm from power cables
running parallel. A separate earthed metal cable duct is advisable for such signal cables. If
signal cables intercept with a power cable, they should do so at an angle of 90°.

Control lines longer than 1 m must be laid with a shield and earthed at one side on the fre­quency inverter. The screen is earthed via terminal “CM” in the case of pull-up logic and
pull-down logic (see “Connection Diagrams”, chapters 7.1 to 7.7). If cables have lengths in
excess of 10 m, use a 0–20 mA control signal because of the possibility of parasitics. The
inverter can be switched over to this mode of operation. See parameter

5.2, page 38).
Other loads connected to the mains may produce voltage spikes that may interfere with

functioning of the inverter or may even damage it. Chokes or mains filters can be used on
the mains side to protect the inverter against voltage spikes (resulting from switching large
loads to the mains). Such chokes and filters are available as accessories.

If inverters are operated in switchgear devices or in their close proximity (e.g. in one com­mon control cabinet) in connection with the same power mains, we recommend the follow­ing precautionary measures to suppress interference in the switchgear:

• Wire the coils of contactors, switchgear devices and relay combinations with “RC ele­ments” or with free-wheel diodes.

• Use shielded cables for external control and measuring cables.

• Lay disturbing cables (e.g. power and contactor control circuits) separately and at a dis­tance from the control cables.

3.4 EMC Ordinance (EMC Directive, 89/336 EEC)

24-FSEL

(chapter

HINT!

The frequency inverters were tested in the form of a practical test set-up in a switchgear
cabinet (in accordance with our interference suppression measures in these operating in­structions: “EMC (electromagnetic compatibility)”. The limit values of the standards below
were fulfilled under these conditions:

EMA (Electromagnetic Emission)

EN 50081-1 Basic specification “Emitted interference” (Limit value class A)
or
EN 50081-2 Basic specification “Emitted interference” (Limit value class B)
EN 55011 Emitted interference

EMB (Electromagnetic Interference)

EN 50082-2 Basic specification “Interference immunity”
EN 50140 Electromagnetic fields
EN 60801 Static discharge (ESD)
IEC 801-4 Burst on mains lead/data line

At least the following conditions must be fulfilled for compliance with
the limit values of the aforementioned standards:

• Installation of a mains filter or a mains filter and a motor choke (mains filter and motor
choke are not included in the scope of delivery).

• Laying the motor cable in a shielded configuration.

• Laying the control cable in a shielded configuration.

• Observe general RFI suppression measures (refer to the chapters 3.3.1 and 3.3.4).

As the aforementioned interference resistance tests are based on standardised mains con­ditions, in extreme cases it may happen that the function of the inverter will be lost (mini­mum operating quality). This malfunction can generally be remedied by a RESET of the
inverter. Refer to the chapter entitled “Resetting a Fault” and “Fault Codes” on page 63.

Detailed information and technical data relating to adapted mains filters and chokes can be
found in the chapters 3.3.2, “Mains Filters/Output Chokes” and 3.3.3, “Filter Specifications”.

3.5 Wiring Practices

3.5.1 Applicable Codes

Pay conscientious attention to ensuring that the installation wiring is installed at least in con­formity with the NEC standards. Where local codes exceed these requirements, they must
be followed.

All models are listed by the Underwriters Laboratories, Inc. (UL) and are certified by the Ca­nadian Underwriters Laboratories (cUL) and therefore conform to the requirements of NEC
and CEC. Installations that are to meet the requirements of UL and cUL must be realised
in conformity with the UL and cUL specifications. Refer to the corresponding electrical data
on the rating plates of the ACP 3000 unit and the motor.

3.5.2 Power Wiring

Power wiring are those wires which are connected during installation to the power circuit
terminals, L1, N, L2, L3, M1, M2, and M3. Power wiring must be selected as follows:

1. Use only VDE, UL or cUL recognized wire.

2. Wire voltage rating must be a minimum of 300 V for 230 VAC systems, and 600 V for
400 VAC systems.

ATTENTION!

3.5.3 Control Wiring/Interface

ATTENTION!

3. The core cross section and the associated fuse are given in the tables in chapter 3.6.2,
page 22. The wires must consist of copper and be designed for insulation temperatures
of 60 °C or 75 °C.

4. Grounding must be in accordance with VDE, NEC and CEC.

NOTES:
Never connect input AC power to the motor output terminals M1, M2 and M3 or dam-

age to the drive will result.

The output voltage of variable-frequency controllers contains high-frequency components
that might cause disturbances in other installations. Therefore, avoid laying control cables
and mains input cables in the same cable duct or conduit together with the output cables
from the converter to the motor (see also chapter 3.3.4, “Interference Suppression Meas­ures”).

All interfaces or control inputs and outputs possess only basic insulation by the
mains and must be incorporated in a further protective measure.

Use a dummy plug as additional protection if interface J22 is not allocated.

This is wiring connected to the control terminal strip (20 terminals). It must be selected as
follows:

1. Shielded wire is recommended to prevent electrical noise interference from causing im­proper operation or nuisance tripping. Only connect the screen on one end to the “CM”
terminal on the converter’s control terminal strip (see also chapter 3.3.4, “Interference
Suppression Measures”).

18

2. Use only VDE, UL or cUL recognized wire.

3. Wire voltage rating must be a minimum of 300 V for 230 VAC systems, and 600 V for
400 VAC systems. This is Class 1 wire.

4. Never run the control wiring in the same conduit or raceway with power wiring.

ACP 3000 — 0.37–15.0 04_GB

Berges electronic • D–51709 Marienheide-Rodt • Tel. [phone] • Fax [phone]

5. Do not use wire end ferrules for the control terminals. The terminals are designed

so that the wires can be inserted in the terminals after twisting the individual
wires.

3.6 Mains Power Connection

The frequency inverters are designed for installation in a switchgear cabinet and for
permanent connection.

To guarantee lasting operating safety and reliability, the inverter must be connected expert­ly in accordance with the valid electrical standards. Attention must be paid to good insula­tion from earth potential on the power terminals.

An AC system with a nominal voltage of 230 V (50/60 Hz) must be connected to mains ter­minals L1, N and PE or a three-phase system with a nominal voltage of 400 V (50/60 Hz)
to terminals L1, L2, L3 and PE (pay attention to rating plate). The neutral point must be
earthed (TN-C system).

Ensure a voltage balanced to earth or phase to phase when feeding in the mains power
through an isolating transformer (star point must be earthed).

Frequency inverters must not be connected via a residual-current-

operated circuit-breaker as the sole protective measure!

The single exception below permits connection of a frequency inverter via a residual-cur­rent-operated circuit-breaker as the sole protective measure:

• Installation of a residual-current-operated circuit-breaker of the newest design for fre-

quency inverters up to 4 kVA (input voltage 1 × 230 V) with MOBILE connection.

This residual current-operated circuit breaker must be suitable for alternating and pul­sating DC leakage current. Residual-current-operated circuit-breakers of this type bear

the symbol .

Reliable tripping of the residual-current-operated circuit-breaker is not ensured in
the case of frequency inverters up to 4 kVA (input voltage 3 × 400 V) with MOBILE
connection; an additional protective measure must be used for this reason. Also see

the diagram below.

In the case of frequency inverters with PERMANENT connection (input voltage 1 ×
230 V and 3 × 400 V), another protective measure must always be used in addition to
the residual-current-operated protective device. Also see the diagram below.

The protective function of the residual-current-operated circuit-breaker is no longer ensured
due to leakage currents from interference suppression capacitors in the inverter and DC
components in the fault current. All devices connected to this residual-current-operated cir­cuit-breaker (and persons touching them) are no longer protected in the event of a fault.

Flow diagram of the requirements relating to the combination of frequency inverter

and residual-current-operated protective device

The inverter will be destroyed if the mains feeder is confused with the motor cable.
The DC link capacitors must be reformed if the inverter you wish to connect has been out

of operation for more than a year. To do this, connect the inverter to voltage for approx. 30
minutes. The inverter should not be loaded by connected motors during forming.

3.6.1 Mains Conditions

Permissible fluctuation of the mains voltage amounts to around ±10% of the rated
voltage. If the mains voltage should exceed or fall below these limits, the inverter will
be deactivated automatically as the result of the undervoltage or overvoltage.

When applying the inverter to line voltages other than the factory default values (230 VAC
or 460 VAC), be sure to set parameter

Adaptation to rated line voltages outside the permissible range is possible by means of au­totransformers. Calculation according to the formula below is recommend:

U

P

T

D

NOTE:

Exercise caution when using the ACP 3000 under the conditions of a low-voltage network.
An inverter from the ACP 3000 series is fully functional when connected to an alternating
current of 370 V, for example. However, the maximum output voltage is limited to 370 VAC.
If the motor is rated for a mains voltage of 400 VAC, this can lead to higher motor currents
and overheating of the motor. It must be ensured that the connected mains voltage cor-

responds to the rated voltage of the motor.

parameters. If you are unsure about this feature,

consult section 5.2 or BERGES.
Phase voltage imbalance of the input AC source can cause unbalanced currents and ex-

cessive heat in the input rectifier diodes and in the DC bus capacitors of the ACP. Phase
imbalance is calculated by the following method:

If the resulting phase imbalance exceeds 2%, consult your local power company or plant
maintenance personnel and ask them to investigate this problem and recommend methods
of correcting this condition.

Phase imbalance can also cause damage to motors running direct on line. A 2% imbalance
requires a 5% derating factor on the motor, 3% imbalance requires a 10% derating. 4% re­quires an 18% derating.

NEVER USE POWER-FACTOR IMPROVEMENT CAPACITORS ON THE ACP MOTOR
TERMINALS, M1, M2, AND M3, OR DAMAGE TO THE INVERTER'S SEMICONDUC­TORS WILL RESULT!

It is necessary to provide either a circuit breaker or a fused disconnect switch on the input
AC line in accordance with all applicable electrical codes. The following rules should be
used to select the correct size of the input line fuses or circuit breaker.

b

A. Sizing

The ACP inverter is able to withstand a 150% overload for 60 seconds. Minimum voltage
rating for the protection device should be 250 VAC for models 3300-3 to 3302-2, and 600
VAC for models 3600-7 to 3615-0.

B. Fuse Type

To guarantee a maximum protection of the inverter fuses should be used for current Limi­tation. These fuses should have a breaking capacity of 200,000 A

shows the recommended values in amps for all ACP-inverters.

ATTENTION!

3.6.3 Using Mains Filters

Special protective measures must be observed when using mains filters:

Owing to the leakage current involved (>3.5 mA), attention must be paid to EN 50178 when
using BERGES mains filters. One of the following protective measures must be taken:

ATTENTION!

• The mains filter must be connected separately by laying a second cable that is electri­cally parallel with the PE conductor; this conductor must meet the requirements of IEC
364-5-543 on its own.

2

• The PE conductor must have a cross section of at least 10 mm
diagrams).

• The PE conductor must be monitored by a facility that isolates the inverter from the
mains in the event of a fault (PE conductor monitoring).

The inverter must always be connected permanently (EN 50178) when using mains
filters (leakage current >3.5 mA).

3.6.4 Line Starting

ACP 3000 is designed to provide controlled starting and stopping of AC motors by use of
the keypad or external contacts connected to the control terminal strip. The drive may also
be started by using a maintained contact (2-wire operation). To prevent accidental starting
of the motor, the inverter has linestart-lockout as a standard feature. This provision can be
defeated by programming

The inverter may be started once every two (2) minutes in this mode.

3.7 Motor Connection

Connect the motor cable to the “M1, M2, M3” and “PE” terminals.
The inverter will be deactivated if shorted to the motor terminals.

82-START

(see page 48).

ATTENTION!

The output of the drive will always be three phase. Do not connect single-phase mo­tors to the inverter output terminals M1, M2 or M3.

Never use power factor correction capacitors on the motor terminals M1, M2 and M3,
or damage to the semi-conductors will result.

We recommend PTC evaluation using commercially available devices to achieve effective
protection of the motor.

If interrupting contacts (e.g. contactors or motor protection switches etc.) have to be in­stalled between the motor and inverter, the circuit must be configured so as to ensure that
the “Enable” signal (terminals V+ and FWD/REV by pull-up logic, terminals CM and FWD/
REV by pull-down logic) is deactivated before separation of the inverter/motor connection.
A relay switching time of approx. 30 ms suffices.

In the case of special motors, the corresponding Volt/Hz values can be programmed on the
inverter by means of the parameters
contact BERGES or refer to chapters 5.2 and 9.1.

53-FKNEE

3.8 Reducing Current Surges and Voltage Transients

Voltage spikes caused by coils (inductors operated on the same mains as the inverter) can
lead to malfunctions of the inverter. In cases of this kind, the affected windings of contactors
and relays operated on the 230 VAC mains must be damped by fuses in the form of an RC
series circuit:

• Main Circuit Contactors and Solenoids: C = 0.2 MFD, 500 VDC; R = 500 W, 5 Watts.

• Auxiliary Control Circuit Relays: C = 0.1 MFD, 500 VDC; R = 200 W, 2 Watts.

Free-wheeling diodes must be used on contactors, relays and solenoid coils operated with
direct current. The diodes in question should be fast types with short recovery time. The
diode must be connected in blocking direction in parallel with the winding (see Figure 3.2).

3.9 Function and Use of Terminals

Refer to section 7.1 to 7.7 – Connection Diagrams for power and control wiring examples.

A. Power Circuit Terminals

Power terminals are located on the power module of the ACP 3000 inverter. They are la­belled L1, L2, and L3 for incoming three phase AC line power (L1 and N for incoming single­phase AC line power), and M1, M2, and M3 for the motor connections.

Two ground connections (GND) are provided on the end plate of 0.37 to 4.0 kW IP 21 mod­els (see Figures 3.4 and 3.5), and along the power terminal strip of 5.5 to 15.0 kW IP 21
models (Figure 3.6). Ground connections can be made to the heat sink on chassis models.
The ground screws must be connected to earth ground in accordance with the NEC.

Coil Capacity (VA)

------------------------------------------------------------------

Rated Voltage of Coil (V)

5.5 to 15.0 kW inverters also have two terminals, B+ and B-, that provide access to the DC

bus rails for the addition of external dynamic braking kits, or extra bus capacitors for custom
applications.

B. Control Terminals

The control terminals are located on the bottom edge of the inverter's control board. See
Figures 3.4 to 3.6, page 26/27 and chapter 3.15. These terminals are available for use with
external devices.

The 20-pole control terminal strip of the units, 0.37–4.0 kW, is plugged in and can be re­moved in the upward direction to connect the control cables. To do this, place a flat screw­driver on the metal tabs of the cover securing element and carefully lever off the terminal
strip in the upward direction.

NOTE:
Control input signals must not exceed 24 VDC ±20% potential to ground.
Logic Input Levels:

LOGIC TYPE PULL-UP PULL-DOWN

Active 10–24 VDC 0–3 VDC

Inactive 0–3 VDC 10–24 VDC

The input logic is compatible with either 12 or 24 VDC logic. J20 selects active High or Low
control inputs.

3.10 Terminal Access Cover Removal Hazard of electrical shock.

Disconnect power before working on this drive.
Dangerous voltages exist until the STATUS Indicator is off.

A. IP 21 Enclosures

IP 21 versions of the ACP 3000 inverter are designed to prevent accidental removal of the
terminal access cover. The cover mounting meets UL and NEC specifications for safety.

To remove the access cover from 0.37 to 4.0 kW inverters, loosen the two screws mounted
at the lower corners of the cover (see Figure 3.3). When replacing the cover, a snug fit only
is required. Do not torque the screws or damage to the cover may result.

To remove the access cover from 5.5 to 15.0 kW inverters, insert a small blade screwdriver
into the slots located on the lower left and right corners of the cover. Use a slight twisting
motion while lifting upward to loosen one side then the other, and then lift the cover off the
inverter. To replace, hook the cover onto the two retainers on top of the inverter base and
snap the cover into place.

Connector J22, located on the right side of the ACP 3000 micro-inverter, is used with either
the Remote Keypad Unit (XRK01) or Program Memory Unit (XPM01), both sold separately.
Both options are battery or AC line adapter powered and can be used with any ACP 3000
model to allow remote programming and control of the inverter. The Remote Keypad Unit
can be mounted on another enclosure up to 100 m from the inverter. Programmer options
allow storage of up to ten separate parameter sets.

4 Getting Started

4.1 General Information

Some ACP 3000 Series micro-inverters do not have a digital keypad as standard equip­ment. These models are programmed to operate via the control terminal strip. Use either
option XRK01 (Remote Keypad Unit) or XPM01 (Program Memory Unit) to re-program the
inverter.

Your ACP 3000 micro-inverter is pre-programmed to run a standard 4-pole AC induction
motor; in many cases no additional programming is required.

The advanced digital keypad controls all operations of the inverter. The eight input keys al­low “Press and Run” operation of the motor and straight forward programming of the pa­rameters. To simplify the programming further, the parameters are separated into two
Program Levels:

LEVEL 1 Easily entered by pressing the PROG key at any time. Limits access to the

LEVEL 2 Accesses all parameters including those in Level 1. Used when the more ad-

4.8 Programming Tips

Accessing Parameters

• When the PROG (or SHIFT-PROG) key is pressed after the application of power or a
fault reset,

• If a different parameter is accessed and the Program mode is exited, that parameter is
the first one displayed the next time Program mode is entered.

• The inverter remembers a different “last parameter accessed” for Levels 1 and 2.

• If no key is pressed for 10 minutes while in the Program mode, the drive will automati­cally revert back to the operating mode.

Changing Display Scroll Rate

Three scroll rates are used to speed data entry.

• If either the UP or DOWN arrow is pressed and held for five seconds, the scroll rate will
increase.

• If the SHIFT key is momentarily pressed while pressing one of the arrow keys, the five
second delay will be bypassed.

21-MODE

Table 4.4

will always be the first parameter displayed.

• If the SHIFT key is pressed a second time while pressing an arrow key the display will
scroll at the fastest rate.

Restoring Factory Settings

• Whenever a parameter Data Code is being changed (noted by PRG blinking) the original
factory setting for that parameter can be restored by pressing and releasing both the UP
and DOWN arrows simultaneously and then pressing the ENTER key.

• To restore all parameters to factory settings, or to recall a previously stored parameter
set, see page 48,

4.9 Quick Start

This section is for operators with simple applications who would like to get up and running
quickly and with a minimum amount of reading of the manual. Be sure to read sections 4.1
through 4.8 before proceeding. In many cases your ACP 3000 will perform perfectly without
making any changes to the factory settings.

A. Perform all procedures for installation as specified in section 3 – Installation.

B. Apply AC power to the input terminals. For about two seconds the display will show all

INJURY AND EQUIPMENT FAILURE!

segments active (see Figure 4.2). The STATUS indicator will then turn red (indicating a
Stop condition) and the display will change to:

Figure 4.3

C. The factory settings correspond to control via the analog input VIN1. Activate terminal

FWD or REV. The FWD and REV keys are thus ineffective. The display will e.g. change
to:

Figure 4.4

D. Control the VIN1 terminal with 0–5/10 V or 0/4–20 mA. When the display gets to 0.1 Hz,

the inverter will start to produce an output. The motor will already begin to run with a cor­respondingly low load. When the motor starts to turn, check the rotation. If the motor is
turning in the wrong direction, PRESS STOP, REMOVE AC POWER AND WAIT FOR
ALL INDICATORS TO GO OUT. After the STATUS indicator has gone out, reverse any
two of the motor leads at M1, M2 or M3.

E. The inverter is preset to run a standard 4-pole AC induction motor to a maximum speed

of 50.00 Hz with both Acceleration and Deceleration times set to 3.0 seconds. See sec­tion 9.1, “Parameter Code Summary” for a complete list of all factory settings.

inverter to the driven motor. Refer to the graphic presented with parameter 67 for a more
in-depth understanding of this parameter.

Data codes “0” through “3” provide for the use of a “standard” motor that typically has a lim­ited continuous constant torque operating speed range. With these data codes, the degree
of overload permitted by the drive depends on the output frequency. Lesser degrees of
overload are permitted at lower speeds.

Data codes “4” through “7” provide for the use of an “inverter duty” motor that has a more
extensive continuous constant torque operating speed range. With these data codes, the
overload performance follows the curve designated “>40 Hz” regardless of operating fre­quency.

As you adjust between “0” & “3” and “4” & “7”, you get various inverse time characteristics.
Data codes “0” and “4” give you the characteristic depicted by the scale designated “C”.
Data codes “1” and “5” work on scale “B” and codes “2” and “6” on scale “A”. With data

12 and 16 kHz levels automatically shift to 6 and 8 kHz respectively in the event of low out­put voltage or if derating is exceeded. In Autoselect, the inverter runs at 16 kHz then auto­matically shifts to 8 kHz in the event of low output voltage, if the derating is exceeded, or if
inverter temperature exceeds 70 °C. If inverter temperature further exceeds 85 °C, the in­verter shifts to 4 kHz. Upshifting occurs if the temperatures drop below these thresholds.

6PI Controller

6.1 Introduction

ACP 3000 inverters have a built-in PI (Proportional-Integral) Controller that makes it possi­ble to control a process by adjusting motor speed using a reference input and a feedback
input. When PI control is enabled, several new parameters (as well as new data codes for
some existing parameters) become available to support PI control.

This section first provides an overview of how PI control operates. Following this discus­sion, the new parameters and data codes are described.

6.2 Overview of PI Control

Figure 6.1 on the next page provides a flowchart of PI control. The characteristics of PI con­trol are set with the

81-PRGNO

Direct- or Reverse-Acting Loop

Slow or Fast Rate of Integration

• A slow rate of integration is usually selected for processes with long time constraints (for
example, thermal and fluid level controls). On the other hand, a fast integration rate is
utilized for processes with short time constraints (such as mechanical systems and pres­sure loops).

Whether Feed-Forward is Active

• Feed-forward is useful in situations where the reference value has a direct relation to the
feedback signal, such as controlling motor speed in a closed loop. Note that feed-for­ward should be enabled when attempting to close a speed loop.

Whether the PI Controller is turned on and off via the PS3 input.

The PI Controller operates within the limits set by parameter
establishes the frequency band across which the value of the integrator and the output of
the PI Controller may vary. If Feed-Forward is active, the output of the PI Controller is the
reference frequency
Note that the final output of the PI Controller cannot be less than 0.00 Hz nor greater than

400.00 Hz.

The output of the PI Controller is sent to the ASIC after the proper frequency conversion.
The controller works in one direction of rotation which must be set by FWD and REV com­mands. A change in direction while the controller is active yields unpredictable results.

The PI controller is limited in its application by the minimum resolution available through the
feedback terminal. Since the feedback terminal voltage is scaled through an 8-bit analog­to-digital converter, the reaction of the PI loop is reduced.

For example, if the inverter is set to run from 0.00 to 60.00 Hz and the feedback is coming
from a tachometer rated at 50 V/1000 rpm and conditioned to be between 0–10 V with 2000
RPM being full scale, then the minimum change that the 8-bit A/D converter can register is
8 rpm. This means that, worst case, the speed can drop by 8 rpm when a load is applied,
but typical accuracy is ±2%.

Input CTS or a STOP command (or inputs FWD and REV active at the same time) stops
the inverter and resets the integrator part (sIPart) of the PI Controller when the value of

falls below 0.10 Hz.

A. Configuration of Inputs

The PI reference value is input from either the keypad or the VIN2 terminal. The PI feedback
value is input from the VIN1 terminal. An error signal is calculated by the microprocessor
which adjusts the speed of the inverter within a range limited by the

The PI feedback input (VIN1) is selectable through J20 as 0 to5 VDC, 0-10 VDC, 0 to 20
mA, or 4 to 20 mA. The PI reference input (VIN2) is selectable through J20 as 0 to 5 VDC
or 0 to 10 VDC.

Parameter
from the minimum. This parameter must also be set to 16, 17, 18, or 19 to use VIN2 as the
reference input. Enabling the PI Controller without properly setting
the use of a combination of VIN1 and VIN2 as the reference signal which will give unpre­dictable results.

B. Scaling the Feedback Input

The feedback input (VIN1) is scaled between 0.00 Hz and 1.125 times FMAX. For example,
if VIN1 is set to “direct” and FMAX is 60.00 Hz, then a full scale feedback signal will corre­spond to 67.50 Hz.

This feedback input can also be scaled, via
range of 0 to 1.99. For example, if B5-KIN = 64, then a full scale feedback signal would cor­respond to 33.75 Hz.

The function of scaling is to compensate the input for conditioning difficulties of the feed­back signal. For instance, if the feedback is from an analog tachometer that gives a 50 V /
1000 rpm signal and the inverter is set up to have an FMAX of 60.0 Hz (which means that
VIN1 needs to read a signal of 67.5 Hz), then the maximum voltage from the tachometer
will be 101.25 V.

This means that a voltage divider scaled to 0.0987 must be used if a maximum input voltage
of 10 V is desired. Since voltage dividers are rarely exact, parameter

B5-KIN

can be used
to compensate. In this case, the divider gain was actually 0.100. This means that the input
will be off scale by a factor of 1.01 which can be compensated by scaling to 0.987 or

set to 126. See page 54 for an equation for calculating

9.3 Options

A. XRK01 – Remote Keypad Unit

The XRK01 – Remote Keypad Unit (RKU) is a portable, hand held accessory. When con­nected to an ACP 3000-inverter, it will function in parallel with an existing keypad or allow
a chassis model to be controlled and programmed. The RKU is powered by a 9 V alkaline
battery (supplied) or an optional AC adapter (PA24DC). Auto Power Down and backlight
control features conserve battery life by automatically turning the RKU off after a specified
time period and allowing selected use of the display backlight.

B. XPM01 – Program Memory Unit

The XPM01 – Program Memory Unit (PMU) is another portable, handheld accessory. When
connected to an ACP 3000-inverter with software revision 13.1 or greater, it allows opera­tion and programming like the RKU. In addition, it allows up to ten different parameter sets
to be stored internally. Any one can be downloaded to the inverter's active memory or cus­tomer parameter set. Uploading parameter sets from an inverter to a PMU memory location
is also possible. The PMU is powered by a 9 V alkaline battery or the AC adapter (both sup­plied). Auto Power Down and backlight control features conserve battery life by automati­cally turning the PMU off after a specified time period and allowing selected use of the
display backlight.

C. XRP01 – Remote Panel Keypad

The XRP01 Remote Panel Keypad is a IP 54 rated, panel mountable accessory. When
properly installed, the XRP01 seals into the host enclosure, assuring that the IP 54 integrity
is preserved. When connected to an ACP 3000 Series inverter, it will function in parallel with
the existing keypad to allow the inverter to be controlled and programmed. The XRP01 is
self powered and can be powered by an optional external AC adapter (PA24DC) or a cus­tomer supplied +24 VDC source.

D. XRP02 – Remote Panel Programmer

The XRP02 Remote Panel Programmer is a IP 54 rated, panel-mountable accessory.
When properly installed, the XRP02 seals into the host enclosure, assuring that the IP 54
integrity is preserved. When connected to an ACP 3000 Series inverter with software revi­sion 13.1 or greater, it allows operation and programming like the XRP01. In addition, it al­lows up to ten different parameter sets to be stored internally. Any one can be downloaded
to the inverter's active memory or customer parameter set. Uploading parameter sets from
an inverter to an on board memory location is also possible. The XRP02 is self powered
and can be powered by an optional external AC adapter (PA24DC) or a customer supplied
+24 VDC source.
