The PowerFlex 7000 utilizes a Pulse Width Modulated (PWM) –

This topology offers a simple, reliable, cost-effective power structure that is easy to apply to a wide voltage and power range. The power semiconductor switches used are easy-to-series for any medium voltage level. Semi-conductor fuses are not required for the power structure due to the current limiting DC link inductor.

filtering and current limiting features to a line side short circuit fault. The line current and voltage waveforms are also shown in Figure 1.2. The line current THD is approximately 4.5%, while line-to-line voltage THD is approximately 1.5%. (THD of line voltage is a function of system impedance.) Input power factor with the AFE rectifier is near unity throughout a typical operating speed range for variable torque loads.

Figure 1.2 – AFE rectifier and its input current/voltage waveforms

b) Line-to-line voltage at PCC

The AFE rectifier can be used in conjunction with a rectifier duty

isolation transformer or with an AC line reactor (as shown in Figure 1.2).

Isolation transformers are available:

1) Integral to the Drive

2) Remote indoor dry type, or

3) Outdoor oil-filled type

This allows for maximum flexibility in dealing with floor space,

installation cost and control room air conditioner loading.

“Direct-to-Drive” Technology Reduce the cost, size and weight of your medium voltage drive

system with the Allen-Bradley PowerFlex 7000 with Direct-to-Drive technology. This is the first and only technology that allows you to directly connect a medium voltage drive to utility power without the requirement of an isolation transformer. Isolation transformers with multiple secondary windings are required for traditional AC drives to address line-side harmonic concerns and common mode voltage. However, typical isolation transformers are large, heavy, costly, complex and inefficient. Direct-to-Drive technology combines an Active Front End (AFE) rectifier to dramatically lower line-side harmonics and a patented DC link inductor to address common mode voltage at its source. By addressing harmonics and common mode voltage, the isolation transformer becomes redundant. This reduces system complexity to maximize uptime and increases system efficiency to lower operational costs. Exceptional output voltage and current waveforms, true of our entire product line, make this ideal for retrofit applications and allow the use of standard motors for new applications.

1-6 Overview of Drive

Motor Compatibility The PowerFlex 7000 achieves near sinusoidal current and voltage

waveforms to the motor, resulting in no significant additional heating or insulation stress. Temperature rise in the motor connected to the VFD is typically 3 °C (5.4 °F) higher compared to across-the-line operation. Voltage waveform has dv/dt of less than 10 volts per microsecond. Reflected wave and dv/dt issues often associated with VSI (voltage source inverter) drives do not exist with the PowerFlex

7000. Typical motor waveforms are shown in Figure 1.3. These motor friendly waveforms are achieved by utilizing a selective harmonic elimination (SHE) pattern in the inverter to eliminate major order harmonics, in conjunction with a small output capacitor (integral to the drive) to eliminate harmonics at higher speeds.

Standard motors are compatible without de-rating, even on retrofit

applications.

Motor cable distance is virtually unlimited. This technology is capable

of controlling motors up to 15 km (9.3 miles) away from the drive.

Safety and Codes

W A R N I N GW A R N I N G

General Handling Procedures Refer to “General Handling Procedures for PowerFlex 7000 Medium

Voltage Drives”, publication no. 7000-IN002_-EN-P supplied in the drive shipment (affixed to the drive). Additional copies can be ordered through your local Rockwell Automation Sales office.

Drive Storage If it is necessary to store the drive, be certain to store in a clean dry

dust free area.

Storage temperature should be maintained between -40°C and 70°C (-40°F and 185°F). If storage temperature fluctuates or if humidity exceeds 95%, space heaters should be used to prevent condensation. The drive should be stored in a heated building having adequate air circulation. The drive must never be stored outdoors.

The Canadian Electrical Code (CEC), National Electrical Code (NEC), or local codes outline provisions for safely installing electrical equipment. Installation MUST comply with specifications regarding wire type, conductor sizes, branch circuit protection and disconnect devices. Failure to do so may result in personal injury and/or equipment damage.

2-2 Drive Installation

Siting of the Drive Site Considerations

The standard environment in which the equipment is designed to

operate is:

• Elevation above sea level less than 1000 meters (3250 feet)

• Ambient air temperature between 0°C (32°F) and 40°C (104°F)

• Relative humidity of the air not to exceed 95% non-condensing

For the equipment to operate in conditions other than those specified

consult the local Rockwell Automation Sales office.

The equipment requires the following site conditions:

(A) Indoor installation only, no dripping water or other fluids

(B) Clean air for cooling requirements

drawings for the location of the anchoring points.

(D) The room in which the equipment is located must allow for full

opening of the doors of the equipment, typically 1200 mm (48 inches). Also, allowances have to be made for clearance for fan removal. This fan allowance must be greater than 700 mm (27.5 inches) above the drive.

Dimension drawings can be obtained by contacting the local Rockwell Automation Sales office. The equipment does not require rear access for servicing.

(E) Allowance must be made for the stream of cooling air which

exits the drive at the top. The flow of cooling air into and out the drive must be kept clear and uninhibited.

(F) The room in which the equipment is located must be large

enough to accommodate the thermal losses of the equipment since air conditioning may be required; the ambient temperature must not exceed that for which the equipment is rated. The heat created by the drive is directly proportional to the power of the motor being driven and the efficiency of equipment within the room. If thermal load data is required contact the Rockwell Automation Sales office.

(G) The area in which the drive is located should be free of radio

frequency interference such as encountered with some welding units. This may cause erroneous fault conditions and shut down the drive.

7000A-UM151D-EN-P – March 2013 7000 “A” Frame

Drive Installation 2-3

(H) The equipment must be kept clean. Dust in the equipment

decreases system reliability and inhibits cooling.

(I) Power cable lengths to the motor are virtually unlimited due to

the near sinusoidal voltage and current waveforms. Unlike voltage source drives, there are no capacitive coupling, dv/dt, or peak voltage issues that can damage the motor insulation system. The topology utilized in the PowerFlex 7000 medium voltage AC drive does not produce dv/dt or peak voltage problems, and has been tested with motors located up to 15 kilometers from the drive.

(J) Only personnel familiar with the function of the drive should

have access to the equipment.

(K) The drive is designed for front access and should be installed

with adequate and safe clearance to allow for total door opening. The back of the unit may be placed against a wall although some customers prefer back access also.

A T T E N T I O NA T T E N T I O N

Generator Note:

A T T E N T I O NA T T E N T I O N

An incorrectly applied or installed drive can result in component damage or a reduction in product life. Ambient conditions not within the specified ranges may result in malfunction of the drive.

Verify that the load is not turning due to the process. A freewheeling motor can generate voltage that will be back-fed to the equipment being worked on.

7000 “A” Frame 7000A-UM151D-EN-P – March 2013

2-4 Drive Installation

Installation When the drive has been placed at its installation area, the lag bolts

that fasten the shipping skid to the drive must be removed. The drive is moved off the shipping skid and the shipping skid can be discarded.

Position the drive in its desired location. Verify that the drive is on a

level surface and that the position of the drive will be vertical when the anchor bolts are installed.

The location of the anchor points is provided with the dimension

drawing of the drive.

Install and tighten the anchor bolts. (M12 or ½” hardware required).

Engineering bolt systems are required for seismic requirements. Consult factory.

Remove the top lifting angles, retain the hardware.

Install the hardware from the lifting angles in the tapped holes at the

top of drive; this prevents leakage of cooling air as well as keeping dust out of the equipment.

Installation of Exhaust Air Hood

On the top of the cabinet with the cooling fan, a sheet metal exhaust

hood is to be installed. The components to make up the exhaust hood have been packaged and shipped with the drive. (For drives with an acoustic hood, the components are shipped assembled. See Figure 2.2)

The first step is to remove the protective plate covering the fan

opening on the drive. It is a flat cover plate bolted to the top plate. Remove the bolts and plate and set aside for re-use.

Secondly, loosely assemble the two L-shaped panel components

shipped with the drive as per Figure 2.1.

IEC Component and

PowerFlex 7000 electrical drawings use conventions that are based

Device Designations

on IEC (International Electrotechnical Commission) standards, while remaining basically compatible with North American ANSI (American National Standards Institute) standards. The symbols used to identify components on the drawings are international and a full listing of the symbols is given as part of each PowerFlex 7000 electrical drawing (ED) set. The device designations used on the drawings and labeling are also listed with explanations on each drawing set.

Wiring identification uses a source/destination wire number

convention on point to point multi-conductor wiring and in situations where the system is warranted. The wire-numbering system of unique, single numbers for multi-drop and point to point wiring continues to be used for general control and power wiring. Wiring that connects between the sheets or that ends at one point and starts at another point on a drawing has an arrow and drawing reference to indicate the ongoing connection. The drawing reference indicates the sheet and the X/Y coordinates of the continuation point. The reference system is explained on a sheet in each drawing set. The unique wire numbering system serves as confirmation that the correct wire is being traced from sheet to sheet or across a drawing. Wires in multi-conductor cables are typically identified by color rather than by number. The abbreviations used to identify the colors on the drawings are fully identified on a sheet in the drawing set.

Power Wiring Selection The following tables identify general wire selections that will be

encountered when installing the PowerFlex 7000 “A” Frame drive line-up.

General Notes:

Adherence to the following recommended field power cabling

insulation levels for medium voltage drives will help to ensure trouble-free start-up and operation. The cable insulation level must be increased over that which would be supplied for an Across-theline application with the same rated line to line voltage.

Either shielded or unshielded cable may be used based on the criteria

considered by the distribution system designer. However, NEC requires shielded cables for installations above 2 kV.

Note 1: Steel conduit or cable tray may be used for all PowerFlex 7000 “A” Frame Drive power or control wiring, and steel conduit is required for all PowerFlex 7000 “A” Frame Drive signal wiring. All input and output power wiring, control wiring or conduit should be brought through the drive conduit entry holes of the enclosure. Use appropriate connectors to maintain the environmental rating of the enclosure. The steel conduit is REQUIRED for all control and signal circuits, when the drive is installed in European Union countries. The connection of the conduit to the enclosure shall be on full 360 degree and the ground bond at the junction shall be less than 0.1 ohms. In EU countries this is a usual practice to install the control and signal wiring.

Note 2: Spacing between wire groups is the recommended minimum for parallel runs of 61 m (200 feet) or less. Note 3: The customer is responsible for the grounding of shields. On drives shipped after November 28/02, the shields are removed from the drive boards. On

drives shipped prior to November 28/02, all shields are connected at the drive end and these connections must be removed before grounding the shield at the customer end of the cable. Shields for cables from one enclosure to another must be grounded only at the source end cabinet. If splicing of shielded cables is required, the shield must remain continuous and insulated from ground.

Note 4: AC and DC circuits must be run in separate conduits or trays. Note 5: Voltage drop in motor leads may adversely affect motor starting and running performance. Installation and application requirements may dictate that

larger wire sizes than indicated in IEC / NEC guidelines are used.

The wire sizes must be selected individually, observing all applicable

safety and CEC, IEC or NEC regulations. The minimum permissible wire size does not necessarily result in the best operating economy. The minimum recommended size for the wires between the drive and the motor is the same as that used with an across-the-line starter. The distance between the drive and motor may affect the size of the conductors used.

Consult the wiring diagrams and appropriate CEC, IEC or NEC

regulations to determine correct power wiring. If assistance is needed, contact your local Rockwell Automation Sales Office.

Power Cabling Access The drive is built with provision for either the top or bottom power

cable entry.

Cable access plates are provided on the top and bottom plates of the

connection cabinet identified by the customer specific dimension drawing (DD).

To access the customer power cable terminations

Cable connections are located behind the medium voltage door of the

Connection/Cabling cabinet. Location of power terminals for various drive configurations are as indicated in Figures 2.21, 2.19 and 2.22.

In the case of the cabling cabinet with starter, the removal of internal

barriers and duct covers located on the left side of the cabinet may be required to facilitate the routing of line cables. This can be accomplished by removing the hardware securing the barrier/cover and sliding it toward the front of the cabinet for removal. In addition the fan housing and cover plate (if already installed) located on the top of the cabinet must be removed to allow routing and termination of line cables. All barriers/covers must be replaced, by reversing the above sequence, before applying medium voltage.

The installer is responsible for modifying the power cable access

plates to suit their requirements.

Note that appropriate connectors must be used to maintain the

environmental rating of the enclosure.

Power and Control Wiring Drive line-ups (i.e. Drive and Input Starter) which are delivered in

two or more sections, for ease of handling, will require that the power and control wiring be re-connected. After the sections are brought together, the power and control wiring is to be re-connected as per the schematic drawings provided.

Control Cables

Control cable entry/exit should be located near the terminal block

'TBC' – the customer's connections are to be routed along the empty side of the TBC terminals. These terminals are sized to accept a maximum #14 AWG. The low voltage signals (includes 4-20mA) are to be connected using twisted shielded cable, with a minimum #18 AWG.

Of special concern is the tachometer signal. Two tachometer inputs

are provided to accommodate a quadrature tachometer (senses motor direction). The tachometer power supply is isolated and provides +15 Volts and a ground reference. Many tachometer outputs have an open collector output, in which case a pull-up resistor must be added to ensure that proper signals are fed to the system logic. (Refer to Appendix A "When is a Tachometer Required?" to see if one needs to be supplied.)

Low voltage signals are to be connected using

I M P O R T A N TI M P O R T A N T

twisted shielded cable with the shield connected at the signal source end only. The shield at the other end is to be wrapped with electrical tape and isolated. Connections are to be made as shown on the electrical drawings (ED) provided.

Grounding Practices The purpose of grounding is to:

• provide for the safety of personnel

• limit dangerous voltages on exposed parts with respect to ground

• facilitate proper over current device operation under ground fault conditions, and

• provide for electrical interference suppression

Generally, the means used for external grounding

Each power feeder from the substation transformer to the drive must

be provided with properly sized ground cables. Utilizing the conduit or cable armor as a ground is not adequate.

Note that if a drive isolation transformer is used, the WYE secondary

neutral point should not be grounded.

Each AC motor frame must be bonded to grounded building steel

within 6 m (20 feet) of its location and tied to the drive's ground bus via ground wires within the power cables and/or conduit. The conduit or cable armor should be bonded to ground at both ends.

Grounding Guidelines and Practices for Drive Signal and Safety

Grounds

When interface cables carrying signals where the frequency does not

exceed 1 MHz are attached for communications with the drive, the following general guidelines should be followed:

• It is good practice for the mesh of a screen to be grounded around its whole circumference, rather than forming a pigtail that is grounded at one point.

• Coaxial cables with a single conductor surrounded by a mesh screen should have the screen grounded at both ends.

• Where a multi-layer screened cable is used (that is, a cable with both a mesh screen and a metal sheath or some form of foil), there are two alternative methods:

– The mesh screen may be grounded at both ends to the metal

sheath. The metal sheath or foil (known as the drain) should, unless otherwise specified, be grounded at one end only, again, as specified above, at the receiver end or the end which is physically closest to the main equipment ground bus.

– The metal sheath or foil may be left insulated from ground

and the other conductors and the mesh cable screen grounded at one end only as stated above

In practice, the cable insulation of an ungrounded, three-phase system must be good for at least a continuous voltage of root three (1.732) times (1.1) times the rated voltage of the supply. (1.732 x 1.1 = 1.9 times the rated lineto-line voltage)

The ground bus is accessible at the top of each of the drive enclosures when the enclosure door is opened (and the low voltage compartment hinged out in the case of the DC link/fan cabinet). It is the responsibility of the installer to ensure that the drive is grounded properly, typically at the point on the ground bus in the cabling cabinet, close to the line cable terminations.

Drive Installation 2-37

Interlocking Access to the medium voltage areas of the drive is restricted by the

use of key interlocking for safety.

At installation the key interlocking is set up so that access to the

medium voltage compartments of the equipment can only be made when the upstream power is locked in the off position.

Additionally, the key interlocking prohibits the upstream power

being applied until the medium voltage drive’s access doors have been closed and locked shut.

It is the responsibility of the installer to ensure that the key

interlocking is installed properly to the upstream equipment.

Chapter Objectives

The chapter deals only with the operation of the operator interface.

This chapter describes how you use the operator interface to modify and obtain information contained within the drive. In this chapter you will learn how to:

• Modify information associated with the initial drive setup.

• View: - drive parameters

- drive status

• View and Reset Alarm Conditions.

• Request printouts of the information in the drive.

• Perform diagnostic trending.

• Modify the operation of the operator interface.

Specific references to a particular parameter are only for illustrative purposes. Refer to PowerFlex 7000 Medium Voltage AC Drive • Technical Data (Publication 7000-TD002_-EN-P) for information about the actual 'tags' within the drive and their use.

Terminology Parameter – A memory location within the drive to which data may

be written to or read. Setting a parameter (i.e. writing to it) will modify how the drive behaves. Prior to using the drive a number of parameters must be set. Additional parameters may be changed while the drive is in use in order to adjust its operation, (i.e. the speed could be changed via a parameter).

Read-only Parameter – A memory location which can only be read.

A read-only parameter contains real-time data and is used to read the current conditions within the drive, such as running speed.

Tag – A generic reference to either a parameter or a read-only

parameter.

PanelView 550 – The PanelView 550 is a product marketed by

Rockwell Automation consisting of a hardware terminal and a software package, integrated into a single product. The Medium Voltage Drive only uses the hardware portion of the product and has replaced the software package.

Operator Interface 3-3

Overview The operator interface used on the PowerFlex 7000 Medium Voltage

Drive is that of the PanelView 550 terminal (Figure 3.1). This terminal however does not behave as a PanelView, as only the hardware for the operator interface has been utilized. The PanelView software has been replaced with unique software to tailor it to the requirements of the Medium Voltage Drive, and its faceplate has been modified (Figure 3.1).

Figure 3.1– PowerFlex 7000 Drive Operator Interface Terminal

Keypad The keypad of the operator interface consists of two rows of five

function keys (item 1 of Figure 3.1) located below the operator interface display area (item 4 of Figure 3.1). In the lower right corner of the operator interface are four keys, which will be referred to as the cursor keys (item 2 of Figure 3.1). Above the cursor keys are data entry keys consisting of the numeric values 0-9, a decimal point (.), a negative (-), a backspace key and a data entry key (item 3 of Figure 3.1).

All keys are of a membrane type. The key is executed upon release.

Function (Softkeys) Keys

Along the bottom of the display area is one or two rows of 'Softkeys'.

These 'Softkeys' represent the physical function keys. The function of the actual keys will vary between displays. The bottom row of keys (i.e. F6-F10) is always shown. The upper row is shown only if they are required for keys (F2-F5). Thus a single row of 'Softkeys' always refers to the keys F6-F10.

7000 “A” Frame 7000A-UM151D-EN-P – March 2013

3-4 Operator Interface

Even though the upper row of Softkeys (i.e. F1-F5) may not be

shown on some displays, the F1-HELP key is always active. (F2-F5) are only active if shown.

Cursor (Selection) Keys

The cursor keys are normally used to select an item on the display.

When an item on the display is selected, that item will be displayed in reverse video. To change the selection, press the key in the desired direction.

On selection screens having more than one page, the page will

automatically change when the cursor is moved beyond the displayed list.

Some displays, such as the Utility screen, use these keys to modify

the data value. Pressing the [cursor up] and [cursor down] keys will change the value by a fine amount, i.e. 1 unit. Using the [cursor left] and [cursor right] keys will change the value by a course amount, i.e. 10 units.

For entries requiring a HEX value, the keys (cursor up/down) are

used to scroll to the desired HEX value.

For parameters which contain an Enumeration string, pressing either

the up or down key will provide a list of options to pick from. Using the cursor keys, make a selection and press enter. If more options exist than can be displayed on the screen, a triangle symbol or inverted triangle to the right of the list will show that there are more selections available in the indicated direction. Continue to use the up/down cursor keys to move to these additional selections.

For parameters that are comprised of bit fields, the left/right keys are

used to move to the desired bit field. The up and down keys toggle the bit between its possible states.

All four cursor keys have an auto feature such that after holding the

key for 2 seconds, the key will automatically repeat at a rate of 5 ‘presses’ per second.

Data Entry Keys

As the name implies, these keys are used to enter data. Pressing the

keys [0] to [9] will enter the corresponding value into the 'editing field'. Pressing the [-] key will change the value to a negative number. Pressing the [.] will allow a fractional value to be entered.

7000A-UM151D-EN-P – March 2013 7000 “A” Frame

Operator Interface 3-5

While entering a value, the value may be edited using the

[backspace] key. This key will remove the right most digit (or decimal point or negative). The help screen uses the backspace key to return to the previous level of help.

The enter key varies depending on the screen. If you are in the

process of a selection operation, the enter key will accept the selection and proceed to a different screen based on the selection in order to complete the operation. If you are in the process of entering data, the enter key will accept the edited data.

What is a Screen? The operator interface uses menu driven screens to perform various

operations on the drive. You can think of a screen as a window or template, overlaying data from the drive. The operator interface combines a screen with the drive data, to formulate what you see on the display area of the operator interface. Individual screens display a particular type of data and allow selected operations to be performed on this data. A number of different screens may be used while performing a single operation.

Components

Although the data displayed on any particular screen will vary, the

general makeup of a screen is the same for all. Figure 3.2 shows a typical screen and its components.

SELECT GROUP:). Knowing the name of the screen will assist you in the orientation of the menu system. On some screens to the right of the screen name, will be the name of the selected item from the previous screen as shown in Figure 3.3.

Some screens have more than one page associated with them. The

current page number and the number of pages which make up the data currently being displayed on the screen is shown in the upper right hand corner, (i.e. showing page 1 of 2 pages).

Along the bottom of the screen are one or two rows of 'Softkeys'

which represent the assignment to the actual function keys. In Figure 3.2, Softkeys F6-F10 are shown. Pressing F8 will display the next page of data.

In the very lower right-hand corner is a small dot. This dot indicates

the healthy state of the operator interface terminal. Under normal conditions this dot will flash at a rate of .5 Hz. During communication errors, the dot will flash at a rate of .1 Hz.

Figure 3.3 – Screen Name & Item

The remainder of the screen shows the data from the drive. The

presentation of the data is dependent on the screen. Screens that allow an item to be selected show the current selection in reverse video. An example of this is shown in Figure 3.2 in which the Speed Control group is selected.

Information Windows

Numerous screens require communications with the drive in order to

function. At times, the duration of this activity will be noticeable to you. During this activity, a special 'window' is used within the current screen to inform you of this activity. The time required for the activity will vary.

7000A-UM151D-EN-P – March 2013 7000 “A” Frame

Operator Interface 3-7

Accessing/Writing to Drive

When first powered up, the operator interface knows very little about

the information in the drive. As each screen is activated, the operator interface requests information from the drive, which it will store within the operator interface for future reference. When the operator interface requests information from the drive, a window is used to display a message "Accessing Drive ...". During this time, the operator interface will not respond to any user input, until the task at hand is completed. You will notice that subsequent activation of the same screen for the same data will be much quicker since the operator interface already has most or all of its required information.

You can selectively choose to download the complete database to the

operator interface on command, thus eliminating the initial access delays. If uninterrupted, the operator interface will automatically download the database on power-up, or during periods of inactivity. Refer to the section on "Advanced Screen Operations - Database Download".

Some screens require that information be written to the drive.

During this task, a window is used to display the message "Writing to Drive...” During this time, the operator interface will not respond to any user input, until the task at hand is completed.

Communication Error

While the operator interface is reading or writing to the drive, it is

possible for communications to be disrupted for a number of reasons. If this were to occur, a special window is used to inform you of this. During this time, the operator interface will not respond to any user input, until the task at hand is completed.

The window for the "Communication Error" can take on two forms.

If a window has already been displayed showing "Accessing Drive" or Writing to Drive", then the communication error message will be added to the window already in use. Some screens constantly read from the drive in order to show real-time data. An example of this is the 'Top Level Menu’. When a communication error occurs on a screen showing real-time data, a window is opened showing a box around the "Communication Error". Two examples of this are shown in Figures 3.4 and 3.5.

In both cases, once communications has been re-established, the

information window will be removed and the operator interface will return to normal operation.

3-8 Operator Interface

Figure 3.4 – Communications Error

Figure 3.5 – Communications Error

Language Changing

When the language used by the drive changes, (either via the

operator interface or an external device), the operator interface must do considerable work. The database strings are all invalidated, the character set for the server is changed and all strings used by the operator interface are linked to the new language. During this possibly lengthy process, the “Language Changing ...” message is displayed.

General Operation

The operations that can be performed on a screen vary depending on

the actual screen being displayed. The majority of the operations are activated by the function keys located along the bottom of the screen. Although the meaning of these keys does change from one screen to the next, there are some functions which are available on most screens and always have the same assignment.

The operations for these latter keys will not be explained within the

description of individual screen operations. They are explained here and apply equally to all screens.

Operator Interface Power-up When the operator interface is powered up or reset, it will go Sequence through two noticeable operations:

a) Linking to Drive - During this phase the operator interface is

establishing communications with the drive communications board. The screen will also show information about the software product contained in the PowerFlex operator interface, such as:

- software part number and revision level

- date and time stamp of program creation

3-10 Operator Interface

b) Obtaining Drive Database - During this phase, the database of

information about the drive is obtained from the drive. Obtaining the database at this point in time is optional and may be aborted by pressing any key on the operator interface. Obtaining the entire database does however speed up subsequent operations since relevant portions of the database do not have to be obtained. (Without obtaining the entire database, the operator interface will access portions of the drive database as required. This slows down the first access to the operation that requires the data. Subsequent operations requiring the same data are not affected). Aborting the download will not affect portions of the database already obtained.

Once the database has been obtained, the operator interface will start

up in one of two modes, depending on to what degree the drive has previously been configured:

a) On an unconfigured drive, the operator interface will enter the

'Setup Wizard' mode. Until the user has gone through the entire 'Setup Wizard', this will be the default mode to power up in. The 'Setup Wizard' can be cancelled at any time by pressing the appropriate softkey.

b) Once the drive has been configured through the 'Setup Wizard',

the Top Level Menu, will be displayed from this point forward. The 'Setup Wizard' can be re-entered via the Setup Menu.

Transfer Data in Memory

The operator interface contains long term storage in two forms.

Flash memory contained in the operator interface is used to store the firmware and optionally language modules and parameters used in the drive. This information can also be stored on a removable flash card that can be taken to another drive.

In order to transfer information from the two forms of memory, press

the [F7] key. This displays a new screen (Figure Error! Reference source not found.) from which all flash memory operations are performed. Refer to the section entitled “Flash Memory Transfers” for instructions on these features.

Picking an Access Level

Access Levels are used in the drive to protect parameters from

unauthorized changes and to filter out the amount of information viewed. Each access level takes on the parameters and permissions of the lower access levels.

The default access level is 'Monitor'. In this level, only a small

subset of the parameter database is viewable. No changes are allowed to any configuration information.

7000 “A” Frame 7000A-UM151D-EN-P – March 2013

3-22 Operator Interface

The next level is 'Basic'. This level and all levels above it allow

changes to be made to any parameter that can be viewed. The number of parameters viewable increases from the previous level. This level will be sufficient for configuring and maintaining the drive for the majority of applications.

The last level intended for normal operation is the 'Advanced' level.

From this level, the drive can be configured in its entirety.

Two additional levels are used for trained service personal and are

only used when physical hardware changes are made to the drive.

Individual PIN numbers protects all levels, except the first. Use the

up/down cursor keys to select the desired access level. Then enter the PIN value for the given access level and press [enter]. If the correct PIN was entered, the access level will change.

Refer to Enter/Modify an Access Level for complete information

on the use of Access Levels.

Select a Parameter Various operations require that a parameter be selected. All

selection operations are done via one of three methods described in this section. All parameters are organized into groups. Selecting via groups is the default method.

The screens associated with the selection process are called

automatically as part of the operation from other screens.

Via Groups

This is the default screen (Figure 3.23) used in the selection of a

parameter. It shows all the groups that are accessible for the operation currently being performed. For example: if you are selecting a parameter, any groups that are showing read-only parameters only will not be shown. The current access level will also affect the number of groups that are currently viewable, and can be selected from. If more than one page of groups exist, press the [F8] and [F9] keys to view the

The name of the selected group currently being displayed is shown after the screen name, i.e. Motor Ratings. Again using the [cursor up] or [cursor down] keys, and if required the [F8] and [F9] keys to change the page, select the desired tag. Press the [enter] key and the selected tag will be used to continue the operation for which the selection process was being used.

From the SELECT GROUP screen (Figure 3.23), the tag can also be

selected via its name by pressing the [F7] key.

Via Name

When you know the name of the tag that you wish to select but do

not know what group it belongs to or are unsure of the full name, this method of selection may be appropriate.

Selecting via a name is initiated from the SELECT GROUP screen

(Figure 3.23) by pressing the [F7] key. This displays the SELECT LETTER screen shown in Figure 3.25.

Using the cursor keys, select (i.e. reverse video) the letter with which

the desired tag starts with. The [cursor up] and [cursor down] keys move vertically within a column, the [cursor left] and [cursor right] key move laterally within the rows. When the appropriate letter has been selected, press the [enter] key.

Via Code

This method of selecting a tag is initiated from the SELECT

LETTER screen (Figure 3.25) by pressing the [F5] key. It allows you to select the tag, given that you know the tag code associated with the desired tag. Every parameter (i.e. tag) has a unique code associated to identify it to devices incapable of making decisions based on a name, such as a PLC for example.

The screen shown in Figure 3.31 is typical of all screens using the

edit text operation. All screens have the F3, F4 and F5 keys in common (if applicable). Once in the 'editing field' all operations are performed on the character in reverse video.

Pressing the [cursor left] and [cursor right] keys will move to the

next character position in the string. Pressing the [cursor up] and [cursor down] keys will cycle through the characters contained in a set, each time the key is pressed. Note that when the first member of a set is displayed, pressing [cursor down] will wrap around to the last member of the set.

There are four sets of characters available. Press the [F3] key to

cycle among the sets. The sets consist of:

a) the upper case letters A-Z. b) the lower case letters a-z. c) the numbers 0-9 and the characters '.' and '-'. d) the characters: space _ ( ) [ ] { } < > | @ # $ % & * ! ^ + = ; : ?

Note: these character set may vary depending on the language

selected.

A special set consisting of A-Z, 0-9 and the underscore character are

used for filenames and cannot be selected via the [F3] key or modified by the [F5] key.

When a letter is in the editing field, pressing the [F5] key may

change its case.

To delete the entire string (i.e. fill it with spaces), press the [F4] key.

To abort the changes to the string being edited press the [backspace]

key. This will restore the string to its contents when the screen was first entered.

The editing operation is completed by pressing the [enter] key.

Changes are not permanently made until the screen is exited via the [F10] key.

Note: The characters entered may only be valid for the currently

selected language. Any characters used which are unique for a given language (i.e. other than the four sets defined above) can only be meaningfully displayed in the selected language, because other languages do not contain the appropriate display characters.

parameters will be obtained from the Drive Identity Module (DIM). The use of the DIM allows each drive to be customized at the factory to the intended application, using all known information at the time of building the drive.

Enter/Modify an Access Level

The drive is protected from unauthorized changes via passwords

consisting of a number between 0 and 65535. These passwords are associated with Access Levels. Each Access Level, (except for the first one 'Monitor') has its own password number (PIN). These values can be unique or all can be set to the same value.

The default level, 'Monitor' does not have a PIN associated with it.

With this Access Level, the drive configuration can be viewed, but no changes are allowed to the parameters. In addition to providing the protection, the Access Levels also filter out the amount of information that can be viewed at each level. On any level, other than 'Monitor', any information that can be viewed may also be modified.

pressing the [F8] key. This will result in the typical screen shown in Figure 3.39 .

The Current Access level is shown. If it states 'Monitor' then you are

restricted to only viewing the basic drive setup. You cannot make any changes. You must be in at least the 'Basic' access level in order to modify any of the drive parameters, and you may only modify the parameters for which you can view at the given access level.

At power-up, the operator interface access level is 'Monitor'. If this

is the current mode and you wish to change any of the setup data, press the [F8] key now in order to change the access level before proceeding into any of the other setup operations available from this screen (Figure 3.40). Refer to the section Enter/Modify an Access Level .

Language Selection

The drive is capable of supporting multiple languages. The operator

interface supports these languages via language modules which must initially be loaded via the flash card (refer to the section Flash Memory Transfers).

To select an alternate language, press the [F9] key on the SETUP

screen. The screen will show all language modules currently loaded as in Figure 3.41. Associated with each language is a module revision level. Use the [cursor up] and [cursor down] keys to select the desired language and press the [enter] key.

The operator interface will switch to the new language selected. It is

possible for other devices attached to the drive to request a language change. If this occurs, the operator interface will switch to the new language, if the required language module is loaded.

Modify Parameters

To change a parameter, Use the up/down arrow keys on the SETUP

screen to select the 'Parameters' option and press the [enter] key. This will begin the selection process of a parameter as described in the section entitled "Select a Parameter". The selection process to change a parameter can also be initiated while displaying the members of a parameter group on the DISPLAY screen (Figure 3.68) by pressing the [F7] key.

When you have successfully selected a parameter, one of three

possible screens will be displayed depending on the type of parameter.

Numerical Value

When the parameter is a numerical value, the MODIFY

PARAMETER screen typical of Figure 3.42 will be displayed. This screen shows:

– the name of the parameter for which you are making the changes

(i.e. Rated motor volt).

– the tag code for the parameter, (i.e. 22).

– the minimum and maximum allowable limits to which the

parameter must be set, (i.e. 4000 to 4160).

– the units in which the parameter data is being displayed

– the actual value of the parameter contained in the drive.

Figure 3.43 – Modify Numerical Value

To be allowed to make changes to the parameter, the operator

interface must be set to an Access Level other than 'Monitor'. (You will be able to view the screen; however, pressing the data entry keys will have no effect). If you are not in the correct level, press the [F8] key in order to gain access to the parameter. Refer to the section entitled Enter/Modify an Access Level for further information on the operation to change the level.

Having gained access, use the data entry keys [0]-[9] to enter the

new value. The [-] key can be typed at any time to enter a negative value. The [.] key is used to enter a decimal point for fractional values. The entered new value can be edited by pressing the [backspace] key. This key will delete the right most character (i.e. number, decimal point or negative sign) shown on the screen. Press the [enter] key to accept the new value as shown in Figure 3.43. If the new value that you entered is outside the limits defined, the new value will not change. For example: If you entered 900 when the minimum value was 4000, the new value will still show 4100.

Some data must be entered in HEX. To accomplish this, use the

cursor up/down keys to scroll through the values 0-F for the right most digit. To accept the digit and enter to the right of the current digit, press the right cursor key. Press the [Enter] key to accept the value.

The value may be edited the same as a value entered from the

numeric keypad.

The new value is not sent to the drive until you exit the screen with

the [F10] key. Prior to this you can modify the new value by repeating the above procedure, or you can cancel the change by pressing the [F7] key. The CANCEL operation returns the new value to that of the actual value.

Enumerated Value

When the parameter is an enumerated value, the MODIFY

PARAMETER screen typical of Figure 3.44 will be displayed. This screen shows:

• the name of the parameter for which you are make the changes (i.e. Operating Mode)

• the tag code for the parameter (i.e. 4)

• the actual value of the parameter contained in the drive.
