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.

(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:

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:

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

• 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

• 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

01/22/96

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

FAULT MENU

Displaying the Fault List

01/22/96

Displaying the

Fault List

(Function # 000)

maintained in the NVRAM and is retained when the drive is powered down or reset. Operation of the drive is totally independent of whether error recording is enabled or not.

There are three functions available under the FLT menu:

FUNCTION # 000

: This function is used to display and optionally clear the OLDEST 16 FAULTS.

FUNCTION # 800

: This function is used to display the NEWEST 16 ERRORS along with their respective time-stamp.

FUNCTION # 801

: This function is used to display/alter the Error Disposition List. This is used to “steer” each error into the Fault List, Error List, or both. The Error Disposition List is consulted any time an error occurs to determine whether it should be reported as an error, a fault, or both.

In order to display and optionally clear the OLDEST 16 Faults, Function # 000 should be used. This function can be selected in two ways:

1. Scrolling

• Press the FLT key followed by enough INC or DEC key repetitions until the PCDU displays:

• Press the ENT key.

Note: Faults that are declared by the

Kernel of the DCU will be displayed as having a PAC block number of 00000. The Kernel is the fixed (i.e. nonchangeable) code for the DCU microprocessor which forms the operating system of the microprocessor. It controls the generation of the various scans, the order of execution of the PAC tasks, the information passed to and from the PAC tasks and the execution of other standard code not directly associated with the PAC tasks such as the control of the CDU or LAN handler. The DCU (Drive Control Unit) refers to the hardware and software used to control the drive. Specifically, it refers to the hardware and software associated with the 68000 microprocessor. The DCU software includes the variable software generated as a result of the PAC program and the fixed software (Kernel) used to control execution of the PAC program.

If errors are present in the Error List

, the PCDU displays the first error recorded in the Error List. A typical PCDU display would be:

The top line indicates which error is being displayed. The bottom line has three parts. The left most item shows how long the drive has been powered up since the error occurred. The range of the time-stamp is such that it will be able to represent more than 2 years time. The elapsed time for an error will be set at the maximum value (745 days) if no new errors have occurred since then, and the drive has not been powered down. There are two possible formats for the time-stamp. It will be expressed in an HH: MM: SS (hours, minutes, and seconds) format if the error occurred within the last 24 hours (with the drive powered-up). It will be expressed as DD-HH:MM (day,hours, minutes) if the error occurred more than 24 hours ago (with the drive powered up). The next item in the display is the “*” character. This character marks a fixed slot in the list. Note that there is really no “start” to the

Trace Monitor

Function #980

The Trace Monitor function # 980 allows real-time data that exists at a given PAC block’s input or output to be displayed. An analogy could be drawn between the function of the Trace Monitor function and troubleshooting a circuit board if that circuit board had a test point for every component on the board. There is only one restriction on tracing PAC blocks. The only points that may be traced on a PAC diagram are those points where one PAC block is directly connected to another PAC block. In other words, the output of a NUMO block or the inputs to a NUMI block cannot be traced since these points are not directly connected to another block.

There are four Trace Buffers available to hold trace information. It is possible to set up the Trace Buffers so that each buffer is collecting different data simultaneously. The Trace Monitor requires the operator to set up each buffer with the PAC block number and the I/O number to be traced if the PAC block has more than one input and/or output. For this reason, a PAC diagram is required if tracing is to be attempted.

The Trace Monitor function is available only on the PCDU. The drive’s LCDU display will show “ Pcdu ” if function # 980 is selected.

The PAC block numbers used in this section are for illustrative purposes only.

The PCDU software will begin to check flags set by the tracing routines and displays the current value (logic or numeric) when it is valid. There are some instances where a request to trace a PAC block cannot be honored. For example, a requested I/O for a valid block may not be available. If this occurs, the PCDU displays:

If the PAC I/O can be traced, the display will show the current value in the proper format. It is important to realize that the Trace Buffer will only be alerted to data from a given block after its buffer has been programmed correctly. If a Trace Buffer has been programmed to capture data from a block located in a conditional scan, that data will not be observed until the conditional scan in question is able to run. When this condition is present, the PCDU will display a waiting message on the bottom line as shown:

The PCDU can display fixed point numeric data, floating point numeric data, or logic data from appropriate PAC blocks. The actual display will vary depending on what kind of data is being viewed. The display

The top line is divided into three parts. The five-digit number following “Blk” is the block number currently in this Trace Buffer. The word “In” or “Out” indicates whether an input or an output is being traced. The two-digit number at the far right is the I/O number of the block. The bottom line is divided into three parts. The single digit following the “#” indicates which of the four Trace Buffers is currently in the display. This number will always be between 0 and 3 inclusive. Following the trace buffer number is either an “R”, an “F”, or the word “LOGIC”. This indicates what type of data is currently being viewed. The “R” means “REAL” (floating point) data, the “F” means “FIXED” (nonfloating point) data, and the “LOGIC” means the I/O being shown is a logic signal. Note that a “FIXED POINT” number may have digits to the right of the decimal point, while an integer will not.

As mentioned before, it is possible to program up to four Trace Buffers to capture data simultaneously. Pressing the INC or DEC keys while viewing a Trace Buffer will cause the PCDU to display the trace data from the next or previous Trace Buffer.

This option is used when entering or editing a PAC block into a Trace Buffer is not desired. The view option will allow user to directly display the contents of the Trace Buffers. Pressing the INC or DEC keys will cause the PCDU to display the trace data from the next or previous Trace Buffer. If a Trace Buffer is not in use, the PCDU will display:

Every parameter that the drive uses has three separate areas in memory associated with it. There is a factory-set default value for each parameter which is stored in the read only EPROM chip. There is an area in the active RAM which the drive uses while it is running. There is also an area in NVRAM reserved for each parameter. The values in the NVRAM area are copied to the active RAM every time the drive is powered up or the RESET button is pressed. This split-level approach makes it possible to return to the last set of “stable” parameters in NVRAM if errors are made while fine-tuning the active drive parameters.

Measurement

Function # 997

The DSD drive has a built-in current regulator SELF TUNING feature. When activated, this feature measures total motor armature circuit resistance and inductance, including wiring. The drive then uses the measured values in conjunction with the parameter entered for “CROSSOVER FREQUENCY” to calculate integral and proportional gains for the current regulator. After running the Power Conversion Unit Parameter Measurement function, the values for armature resistance and armature inductance are stored in NVRAM. It is important to note that it is possible to override the values that have been dynamically calculated for armature resistance and inductance by the “USE SELF-TUNE” item in the Parameter Menu. The dynamically calculated values are used if “USE SELF-TUNE”’ is set to “ON”, while the manually entered values are used if this item is set to “OFF”.

WARNING

Current is circulated through the armature circuit during the Power Conversion Unit Parameter Measurement function. The Power Conversion Unit will reduce the field current to zero on motors with a shunt field in order to minimize motor rotation. However, a PERMANENT MAGNET motor must have its shaft locked mechanically prior to running the Power Conversion Unit Parameter Measurement routine. If the

Diagnostics

01/22/96

The drive has built-in diagnostic routines that can be performed via the PCDU. The Power Conversion Unit diagnostic routines are able to test for three failure modes. The first test that the Power Conversion Unit performs is a test of the three line fuses. Assuming the three line fuses are OK, the Power Conversion Unit then performs a test for shorted SCRs/doubler packs. If this test indicates no shorted SCRs/doublers, the Power Conversion Unit then tests for open SCRs by passing current through the forward bridge followed by the reverse bridge. The results of each test are displayed on the PCDU after each test is completed.

WARNING

Current is circulated through the armature circuit during the Power Conversion Unit Diagnostics function. The Power Conversion Unit will reduce the field current to zero on motors with a shunt field in order to minimize motor rotation. However, a PERMANENT MAGNET motor must have its shaft locked mechanically prior to running the Power Conversion Unit Diagnostics.

FORCING (FRC)

All PAC blocks send their output to, and acquire their input from, fixed locations during normal running operation. These locations used during normal running operation are referred in the Help menu as the normal addresses. During troubleshooting, however, it may be desirable to “force” an input or output of a PAC block to a certain value independent of its normal source. In this situation, the PAC block obtains its input or output from a forcing address. An example of this might be to force a logic input (LOGI block) to a certain state to simulate a RUN or STOP push button being pressed on a operator console station without actually pushing the button. It is also possible to simulate a numeric input (NUMI block) from a thumbwheel switch, whether or not the physical hardware is actually present. The outputs of certain PAC blocks may also be forced. This feature might be used to test lamps (LOGO blocks), relays (LOGO blocks) or analog meters (NUMO blocks) that are controlled by the drive. The seven (7) types of PAC blocks that can be forced are the LOGI, LOGO, NUMI, NUMO, REFO, RDCI, and TACH blocks. Attempts to force any other type of block will result in an error. The following is a description of how to force a PAC block’s input or output via the PCDU.

Note

: When the ESC key is pressed

repeatedly in any menu, the PCDU will back up all the way to the top greeting message. The FRC menu is an exception to this rule. This is done to minimize the possibility of the operator leaving the I/O in the forcing mode without knowing it. If the ESC key is pressed repeatedly and there is at least one I/O currently being force, the PCDU will display the following screen:

This is how the PCDU informs the operator that there is at least one PAC block in the forcing state. It is assumed that the operator has read

the “Forcing active....” message and

therefore is aware of this fact after the F3 key is pressed.
