INTRODUCTION

The Portable Control/Display Unit (PCDU) is an optional device that connects into a drive and allows easy interface between the operator and the drive for setting parameters, viewing drive data, logging faults, and/or troubleshooting. The PCDU has a 30 button membrane-type keypad and a 2 line, 16 character alphanumeric display. The software in the drive is designed to make it unnecessary to have one PCDU for each drive in a system, although this may be desirable. The PCDU may be connected into and removed from any drive while the drive is running without loss of drive data. Some diagnostics require the use of the PCDU since it offers greater flexibility.

Each operation that the PCDU performs can be grouped into one of six different categories called menus. The six menus on the PCDU are HELP, FORCE, MONITOR, PARAMETER, FAULT, and TEST. These menus are represented by the keys labeled HLP, FRC, MON, PRM, FLT, and TST. Pressing any of the menu keys, will bring you to the top selection within that particular menu. The six menus are independent of each other. This feature allows the PCDU to “remember” what function was being performed in one menu while the PCDU is performing a function in a different menu. A single press of the appropriate menu key will return to the most recently used function within that menu.

(Help Menu): This menu offers GENERAL HELP at the top level and “context-sensitive” help for the different operations available in the FRC, MON, PRM, FLT, and TST menus.

(Force Menu): This menu is used to change inputs and/or outputs of a PAC block to a given value. This is done for troubleshooting purposes.

(Monitor Menu): This menu is used for

viewing the values of functions that can not be set directly with the PCDU. Examples of these would be: line speed, motor speed, speed reference or armature current.

(Parameter Menu): This menu is used to change the value of those parameters that can be modified with the PCDU. Examples of these would be: current limits, rated line speed, or accel/decel times.

(Fault Menu): This menu is used to gain access to the FAULT List and the ERROR List within the drive to get a running history of the operation of the drive.

(Test Menu): This menu is used to performed certain diagnostic tasks. Items in this menu include loading factory set defaults for parameters, SCR and fuse testing, and other diagnostic functions.

Some of the PCDU keys have functions which are not always prompted by the display. These keys are:

(Escape): When this key is pressed, it moves the PCDU display one level closer to the top of the current menu.

(Shift): This key toggles in and out of the alphabetic character entry mode. The shift key must be pressed for every key that needs shifting.

(Clear): This key is used when changing a parameter in the Parameter menu. If an error is made when setting a parameter, this key is used to clear the display so that the proper value can be entered.

HELP (HLP) MENU

The PCDU contains “context-sensitive” help. This means that the messages that are displayed after pressing the HLP key will vary depending on what the PCDU is being used for at that moment. GENERAL help is available at the top level, while specific help for each menu will be displayed when the PCDU is operating within that menu. The five remaining help screens are for the FRC, MON, PRM, FLT, and TST, menu keys.

After the PCDU is plugged in and completes its initialization, it will display the following (assuming there are no faults):

• Press the HELP key. The PCDU is now at the GENERAL help level, and it will display the following:

At this point, the PCDU will recognize only five keys. Those keys are: “<––”, “––>”, INC, DEC, or ESC. The INC key speeds up the scrolling rate of the display, while the DEC will slow it down.

• Press the “––>” key to begin scrolling through the help text. The PCDU display now begins scrolling:

START: GENERAL . . .

The PCDU stops scrolling when it reaches the end of a sentence. In the case of the first sentence in the GENERAL help screen, the PCDU display stops at:

• Press the “ ––>” key again to resume scrolling through the help screen.

• Press the “<––” key to halt the scrolling text and display the start of the current sentence. Repeatedly pressing the “<––” will step back to the beginning of previous sentences in the help menu.

Help

Each menu in the PCDU possesses a help text. This help text will provide information pertaining to the specific menu the PCDU is in. As an example, the help text for the Parameter Menu will be accessed:

• Press the PRM key. A typical display in the top level of the PRM menu might be:

If the HLP key is pressed, the Parameter help text will describe what a typical screen in the PRM menu looks like and how to change the parameter value. The first screen of the help text for the Parameter Menu will be:

Any of the following keys: “<––”, “––>”, INC, DEC, or ESC may be pressed to move through the help text. The ESC key will always exit the help function, and return the PCDU to what was being displayed prior to pressing the HLP key. If instead the HLP key is again pressed, the PCDU will return to the GENERAL help text:

<––, ––>, OR ESC << START: GENERAL . . .

<––, ––>, OR ESC << START: PRM HELP . . .

MONITOR MENU

Monitor (MON) Menu

MONITOR (MON)

The MON menu contains the values of functions that can be viewed, but NOT modified. Function codes # 600 through # 799 are reserved for display-only types of values. Function codes for display-only types of values are dependent on the contents of the PAC Diagram for the particular drive.

Example:

Assume the operator wishes to view the armature voltage of the motor. For this example the armature voltage has function code # 610. The appropriate function can be selected in one of two ways:

1. Scrolling

• Press the MON key followed by enough INC or DEC key repetitions until the desired item shows in the PCDU display:

2. Direct Access

• Enter the appropriate function code from the top level of any menu display. The display will change to:

Enter Function Number : 610

ARM VOLTAGE

• Press the ENT key. The display will show:

This display shows the function name on the top line. The present value, units, and the function code are shown on the bottom line. The “M” before the function code indicates that the item in the display is from the MON menu. In order to view the next or previous function in the MON menu, the operator may press the INC or DEC key. Note that there may be a numerical gap in the function codes depending on what the PAC diagram contains. The PCDU will wrap around to the first displayed function if the INC key is pressed while the LAST function is displayed.

(PRM) MENU

Viewing a

Parameter

The Parameter menu contains the settable parameters used by the drive. This menu is used to view and optionally modify those parameters. Function codes # 001 through # 299 are reserved for settable parameters. These function codes are PAC diagram dependent, and the parameters assigned to these codes are therefore defined by the user.

Example:

Assume the operator wants to view the current value for the TACH PULSES/REV. For this example the function number will be # 010. The operator has two ways of selecting the appropriate function:

1. Scrolling

• Press the PRM key followed by enough INC or DEC key repetitions until the desired item shows in the display:

2. Direct Access

• Enter the appropriate function code number (for this example it will be

010) from the top level of any menu display. The PCDU display will change to:

Enter Function Number : 010

TACH PULSES/REV

2500. P/R P010

Parameter

• Press the ENT key. The PCDU now displays:

This display shows the function description on the top line. The present value, units, and the function number are displayed on the bottom line. The “P” before the function number indicates that the item in the display is from the PRM menu. By pressing the INC or DEC key, the operator can view the next or previous parameter.

Example:

The operator from the previous example wants to change the value for the TACH PULSES/REV. After accessing the desired parameter (see “Viewing a Parameter” on page 10):

• Press the ENT key to allow the parameter presently in the display to be changed. This Setup mode is active when the top line of the PCDU display is flashing.

The parameter in the display may be changed in one of two ways:

1. Up to five digits plus a decimal point may be pressed. The “+/-” key may also be pressed. When this key is used, the left-most character (sign digit) will change sign. As soon as the first digit key, “+/-” key, or decimal point key is detected, the INC and DEC keys will be ignored. The PCDU recognizes when decimal points are appropriate, based on the PAC diagram, and handles

the decimal point key and subsequent digits accordingly.

2. The INC and DEC keys can be used to modify any parameter data. The least significant digit of the parameter will be changed by 1 for every INC or DEC key entry. Upon the first INC or DEC key entry, the “+/-” key, the decimal point key, and numeric keys are ignored.

The ENT, CLR, or ESC keys or one of the menu keys may be pressed at any time while modifying a parameter. The PCDU’s reaction to these keys will be:

The ENT key is used to accept the new data in the display. If this key is pressed, the PCDU will exit the Setup mode (top line will stop flashing), and compare the number just entered against upper and lower limits for that parameter. If the number is beyond either limit, the PCDU briefly displays “vLimv” or “^Lim^”, followed by the current active value. “vLimv” and “^Lim^” refer to lower and upper limits, respectively.

Example:

If a value of 250 is entered as the new desired set point while the lower limit is 600 for the TACH PULSES/REV, the PCDU will display:

TACH PULSES/REV

vLIMv. P/R P010

ESC

This display indicates that the new value is below the lower limit. After 1/2 second, the PCDU displays the current active value:

A similar message is displayed if the upper limit is exceeded, but “^Lim^” is shown instead.

The CLR key is used to erase the new data in the display BEFORE the ENT key is pressed. If this key is used, the PCDU will remain in the Setup mode (top line flashing), but the new value will be the current value.

Example:

Assume a new value of 3600 was keyed in for the TACH PULSES/REV, followed by the CLR key. The display will show:

This is the current active value. The ESC key is used to exit the Setup

mode WITHOUT changing the parameter. The top line will stop flashing, and the bottom line displays the present value for the parameter. Any changes made to the parameter in the display are discarded.

These keys will cause the PCDU to display the most recently displayed item in that particular menu. If any of these keys are pressed before the ENT key, the changes made to the parameter being modified are lost.

Note

: All changes become active

values upon pressing the ENT key. They remain active until the

next reset, or until the drive is powered down. When the drive is reset or powered up, the values revert to the values stored in NVRAM (Non-Volatile Memory). If changes are to be permanent, use function # 994 to save the changed values in NVRAM. (See “NVRAM Access”, on page 37.)

Due to PAC programming considerations it may be possible to access a value which can not be changed. In this case the PCDU function will proceed as described until the ENT key is pressed to change the value. Any changes will be ignored, and the value will remain the same.

FAULT MENU

Fault (FLT) Menu

FAULT (FLT)

The drive has two methods available to report errors. Each error condition may utilize ONE or BOTH of the reporting methods.

1. The F

AULT LIST

The most conventional method is called “fault recording”. If this method is enabled for a particular error, the red FAULT LED will light, and a unique fault code will appear on the Standard Control Display Unit (display on drive) at the moment the error occurs.

Each occurrence of a fault is recorded in an area in RAM called the FAULT LIST. The FAULT LIST stores the 16 OLDEST faults and stops recording faults as soon as the 16th fault occurs. This list is erased whenever the drive is powered down or reset. Whether or not the drive stops or continues to run is dependent on the way the particular fault is implemented within the PAC diagram. Most standard faults are set up so that the drive will stop if a fault occurs.

2. The ERROR LIST The second method for error handling is

called “error recording”, and will produce an ERROR LIST. Error recording differs from fault recording in three aspects. First, the error will not be shown on the Standard Control Display Unit, and the red FAULT LED will not light at the moment the error occurs. Second, the ERROR LIST stores the 16 MOST RECENT errors, and always overwrites the oldest errors with the newest errors. Third, this list is
