Product Overview

3 Product Overview

3.1 Introduction

The figure presents the block diagram of the VACON® NX inverter. The inverter mechanically consists of 2 units: the power unit and the control unit.

The power unit contains an inverter bridge which consists of IGBT switches and produces a symmetrical, 3-phase PWM-modulated AC voltage to the motor. To protect the DC-link capacitors, capability of DC-charging is required.

The motor and application control block is based on microprocessor software. The microprocessor controls the motor based on the information it receives through measurements, parameter settings, control I/O, and control panel.

The motor and application control block controls the motor control ASIC which, in turn, calculates the IGBT positions. Gate drivers amplify these signals for driving the IGBT inverter bridge.

Illustration 1: Block Diagram of VACON® NX Inverter

AQ304441431479en-000101 / DPD00909| 15

Operating Guide | VACON® NXI Inverters FI9-FI14

The control panel constitutes a link between the user and the inverter. The control panel is used for parameter setting, reading status data and giving control commands. It is detachable and can be operated externally and is connected via a cable to the inverter. Instead

of the control panel, a PC can be used to control the inverter when connected through a similar cable (VACON® RS232PC –1.5M).

The basic control interface and the parameters (the Basic Application) are easy to use. If a more versatile interface or parameters are required, a more suitable application can be selected from the "All in One" Application Package. See the "All in One" Application

Manual for more information on the different applications. Custom application development can be done with VACON® Programming tool and standard PLC programming languages defined in the IEC 61131/3. External control PLC can be replaced with VACON® NXP

control unit in many applications due to extensive I/O and fieldbus options and easy programmability.

Optional I/O expander boards that increase the number of inputs and outputs to be used are also available. For more information, contact the Manufacturer or your local distributor.

3.7 Available EMC Classes

The EMC Directive provides that the electrical apparatus must not excessively disturb the environment it is used in. It also requires that the electrical apparatus must have an adequate level of immunity toward other disturbances from the same environment.

The compliance of VACON® NX Inverters with the EMC Directive is verified with Technical Construction Files (TCF) and checked and approved by SGS FIMKO, which is a Notified Body. The Technical Construction Files are used to authenticate the conformity of VACON

NX Inverters with the Directive. It is because testing such a large product family in a laboratory environment is impossible. Testing is difficult also because the combinations of installation vary greatly.

5.1 Environmental Requirements

5.1.1 General Environmental Requirements

In environments with airborne liquids, particles, or corrosive gases, ensure that the protection rating of the equipment matches the installation environment. Failure to meet requirements for ambient conditions can reduce the lifetime of the AC drive. Ensure that requirements for humidity, temperature, and altitude are met.

Vibration and shock

The AC drive complies with requirements for units intended for installation in enclosures.

For detailed ambient conditions specifications, see 12.7 Technical Data.

Installation requirements:

• Make sure that there is sufficiently free space around the AC drive for cooling, see 5.2.2 Cooling of FI9 to FI14.

• Some free space is also necessary for maintenance.

• Make sure that the mounting surface is sufficiently flat.

5.1.2 Ambient Temperature and Derating

The power rating of the unit is valid for an ambient temperature of 40 ºC (104 °F). If the device is to be used in higher ambient temperatures, its power rating must be subjected to derating.

Use the following formula to calculate the reduced power:

de=  100 %    40°   /100

Legend:

• Pn = nominal power of the unit

• t = ambient temperature

• x = derating coefficient, see the following list:

- in ambient temperature of 40–50 °C (104–122 °F), use derating factor 1.5%/1 °C (°F)

- For 50–55 °C (122–131 °F) ambient temperatures use derating factor 2.5% / 1 °C (°F).

5.1.3 High Altitude Installation

The density of air decreases when the altitude increases and the pressure decreases. When the air density decreases, the thermal capacity decreases (that is, less air removes less heat) and the resistance to electric field (breakdown voltage/distance) decreases.

The full thermal performance of VACON® NX AC drives is designed for installation up to 1000 m altitude. The electric insulation is designed for installations up to 3000 m altitude (check details for different sizes in Technical Data).

Higher installation locations are possible, when obeying the derating guidelines in this chapter.

For permitted maximum altitudes, see 12.7 Technical Data.

Above 1000 m, decrease the limited maximum load current by 1% for each 100 m.

For information on option boards and I/O signals and relay outputs, see VACON® NX I/O Boards User Manual.

Example:

For example, at 2500 m altitude, decrease the load current down to 85% of the rated output current (100% – (2500– 1000 m) / 100 m x 1% = 85%).

When using fuses at high altitudes, the cooling effect of the fuse decreases as the density of the atmosphere decreases.

When using fuses above 2000 meters, the continuous rating of the fuse:

5.2 Cooling Requirements

5.2.1 General Cooling Requirements

The AC drive produces heat in operation. The fan moves air and decreases the temperature of the drive. Make sure that there is sufficiently free space around the drive.

Make sure that the temperature of the cooling air does not go above the maximum ambient operating temperature or below the minimum ambient operating temperature of the drive.

5.2.2 Cooling of FI9 to FI14

If many AC drives are installed above each other, the necessary free space is 2 x B2 (see illustration 8). Make also sure that the outlet air from the lower drive goes to a different direction than the air intake of the top drive.

5.2.3 Ventilation of the Cabinet

The air must move freely and efficiently through the cabinet and the drive. Make sure that the hot air goes out of the cabinet and does not come back into the cabinet. To achieve it:

• The cabinet door must be provided with air gaps for air intake. See the minimum sizes of inlet air holes in table 6 and the recommended layout in illustration 8.

• Air outlet gaps must be on top of the cabinet. See the minimum sizes of outlet air holes in table 6 and the recommended layout in

illustration: Ventilation of the Cabinet > #X013499 > image_m3m_mbw_qhb.

• If the power unit is placed in the upper part of the cabinet, the fan blower must be in the middle of the cabinet, at the height of the upper ventilation grid.

During operation, air is sucked in and circulated by a fan at the bottom of the power unit.

The ventilation gaps must fulfill the requirements set by the selected protection rating. The examples in this manual apply to protection class IP21.

7.1 Control Unit Components

The control unit of the AC drive contains the control board and additional boards (see illustration 14) connected to the 5 slot connectors (A to E) of the control board. The control board is connected to the power unit through a D-connector or fiber optic cables (FR9).

Illustration 14: Basic and Option Slots on the Control Board

The control unit of the delivered AC drive contains the standard control interface. If the order included special options, the AC drive is delivered according to the order. The next pages contain information on the terminals and general wiring examples. The type code

shows the I/O boards that are installed at the factory. For more information on the option boards, see VACON® NX I/O Boards User manual.

The OPTA1 basic board has 20 control terminals, and the relay board has 6 or 7. The standard connections of the control unit and the descriptions of signals are shown in

For instructions on how to install the control unit that is not attached to the power unit, see VACON® NXP IP00 Drives Installation Manual.

7.3.2 Control Terminals on OPTA1.

7.2 Control Voltage (+24 V/EXT +24 V)

It is possible to use the drive with an external power source with these properties: +24 V DC ±10%, minimum 1000 mA. Use it to externally power up the control board, and the basic and option boards. The analog outputs and inputs at OPTA1 do not work with only +24 V supplied to the control unit.

Connect the external power source to one of the 2 bidirectional terminals (#6 or #12), see the option board manual or VACON® NX I/O Boards User Manual. With this voltage, the control unit stays on and parameters can be set. The measurements of the main circuit (for example, the DC-link voltage, and the unit temperature) are not available when the drive is not connected to mains.

7.4.1 Connecting the Optic Fiber Cables

Context:

In case the fiber cables are not connected, connect them from the optical fiber board (FI9-FI10 and FI13) or star coupler board (FI12 and FI14) to the power module.

CAUTI O N

DAMAGE TO THE COMPONENTS FROM INCORRECT CONNECTIONS

Connecting the cables incorrectly damages power electronic components.

Be careful to connect the fiber optic cables according to instructions.

Prerequisites:

The maximum length of the optical cable is 8 m.

The minimum bending radius for optical cables is 50 mm.

Procedure

1. To access the ASIC board, remove the cable cover in front of the power unit. See 6.4.1 Get Access and Locate the Terminals for FI9-

FI12.

2. Connect the supply cable to the X10 connector on the ASIC board and to the X2 connector on the rear side of the control unit. For FI12 and FI14, connect only power unit 1. Power unit 2 is connected to Asic load resistor.

Terminals X2 and X3 can be in use simultaneously. However, if the +24 V supply from the control I/O terminals (for example, from board OPT-A1) is used, this terminal must be protected with a diode.

3. Connect each cable to the connectors marked with the same number on the ASIC board and on the rear side of the control unit.

4. In FI12 and FI14, connect the 4 fiber cables from the feedback boards to the star coupler board.

5. To prevent damages to the cables, attach the cable bundle at two or more points, at least once at each end.

6. Attach the cable cover on the power unit when the work is finished.

Maintenance

10 Maintenance

10.1 Maintenance Schedule

In normal conditions, VACON® NX Inverters are maintenance-free. To maintain trouble-free operation of the unit, environmental conditions, load, line power, and process control must be within specifications, determined by the manufacturer.

Danfoss recommends annual maintenance inspections and certain component replacements based on specified operational and environment conditions to ensure highest reliability and performance. Refer to the table for maintenance intervals.

We also recommend recording all actions and counter values with dates and time to follow up of maintenance.

Table 16: Maintenance Intervals and Tasks

Maintenance in‐

Maintenance task

terval

24 months

(1)

Reform the capacitors if the unit has not been used for 24 months (see 10.2 Reforming the Capacitors.)

If the unit was in store for much longer than 24 months and the capacitors were not charged, speak to the factory to get instructions before connecting the power.

6–24 months

(2)

• Do a check of the tightening torques of the terminals.

• Clean the heat sink.

• Clean the cooling channel.

• Make sure that the cooling fan operates correctly.

• Make sure that there is no corrosion on the terminals, the busbars, or other surfaces.

• If there is cabinet installation, do a check of the door filters.

• the main fan

• the fan of the LCL filter

• the internal IP54 (UL Type 12) fan

• the cabinet cooling fan/filter

8–15 years

If the unit is kept in store.

The interval is different in different environments.

The expected lifetime for the DC bus capacitor is between 8–15 years depending on the ambient temperature and the average load conditions. Expected service life is more than 15

years when the average load is 80% and the ambient temperature is 30 °.

(3)

Replace the DC bus capacitors.

10.2 Reforming the Capacitors

Context:

The electrolytic capacitors in the DC link rely on a chemical process to provide the insulator between the two metal plates. This process can degrade over a period of years when the drive has been non-operational (stocked). The result is that the working voltage of the DC link gradually falls.

e30bh487.10

Operating Guide | VACON® NXI Inverters FI9-FI14

The correct course of action is to ensure that the insulation layer of the capacitor is ‘reformed’ by the application of a limited current using a DC supply. Current limiting ensures that the heat generated within the capacitor is kept at a sufficiently low level to prevent any damage.

Maintenance

DANG E R

SHOCK HAZARD FROM CAPACITORS

The capacitors can be charged even when disconnected. Contact with this voltage can lead to death or serious injury.

If the AC drive or spare capacitors are intended to be stocked, discharge the capacitors before storage. Use a measuring

device to make sure that there is no voltage. If in doubt, contact your Danfoss Drives® representative.

Case 1: AC drive which has been non-operational or stocked for over 2 years.

1. Connect the DC supply to LI1 and L2 or the B+/B terminals (DC+ to B+, DC- to B-) of the DC-link or directly to the capacitor

terminals. In the NX AC drives with no B+/B- terminals (FR8-FR9/FI8-FI9), connect the DC supply between 2 input phases (L1 and L2).

2. Set the current limit maximum to 800 mA.

3. Slowly increase the DC voltage to the nominal DC voltage level of the AC drive (1.35*Un AC).

4. Start to reform the capacitors.

The time of reforming depends on the time of storage. See illustration 32.

A Storage time (years)

C Reforming time

Illustration 32: Storage Time and Reforming Time

5. After the reforming operation is done, discharge the capacitors.

B Reforming time (hours)

Fault Tracing

11 Fault Tracing

11.1 General Information on Fault Tracing

When the control diagnostics of the AC drive find an unusual condition in the operation of the drive, the drive shows this information:

• This information shows on the display (see 8.5.1 Finding the Active Faults Menu):

- the location indication F1

- the fault code, see the Faults and Alarms section

For option board related fault codes, see the option board manual.

- a short description of the fault

- the fault type symbol, see

- the FAULT or ALARM symbol

• The red LED on the control panel starts to blink (only when a fault shows).

If many faults show at the same time, examine the list of active faults with the Browser buttons.

In the VACON® NX AC drives, there are 4 different types of faults.

Table 17: Fault Types

table 17

Fault type symbol Description

A (Alarm) The type A fault (Alarm) tells about unusual operation on the drive. It does not stop the drive. The 'A fault'

stays in the display for about 30 s.

F (Fault) The type 'F fault' stops the drive. To start the drive again, find a solution to the problem.

AR (Fault Autoreset)

FT (Fault Trip) If the drive cannot start the motor after an AR fault, an FT fault shows. The type 'FT fault' stops the AC drive.

The fault stays active until it is reset, see 11.2 Resetting a Fault. The memory of active faults can keep the maximum of 10 faults in the order in which they were shown.

Reset the fault with the [reset] button on the control panel, or through the control terminal, fieldbus, or the PC tool. The faults stay in the Fault history.

Before asking help from the distributor or the factory because of unusual operation, prepare some data. Write down all the texts on the display, the fault code, the source information, the Active Faults list, and the Fault History.

The type 'AR fault' stops the drive. The fault is reset automatically and the drive tries to start the motor again. If it cannot the start the motor again, a fault trip (see FT, Fault Trip) shows.

11.2 Resetting a Fault

Context:

The fault stays active until it is reset. Reset the fault using these instructions.

Operating Guide | VACON® NXI Inverters FI9-FI14

Procedure

1. Remove the external Start signal before resetting the fault to prevent that the drive starts again without a note.

2. There are 2 options to reset a fault:

- Push the [reset] button on the control panel for 2 s.

- Use a reset signal from the I/O terminal or fieldbus.

The display goes back to the same state it was before the fault.
