    1. OUTLINE

    1.1 MAIN FUNCTIONS

Function Description

    GA7200 can be operated easily with the Drive Mode digital operator.

    Function selection and constant setting for Program Mode GA7200 can be performed with the digital

    operator.

    Monitoring of output frequency, output

    current, output voltage or status of run / stop Monitor Function commands can be performed with the digital

    operator.

    If a fault occurs, its contents order of

    occurrence is displayed. When the power

    Fault Contents Display supply is turned ON, maintenance

    inspection or troubleshooting can be

    performed since fault is recorded.

    ~5~

    1.2 DIGITAL OPERATOR KEYPAD

     Mode Display LED Drive Mode Display Red lamp lights in DRIVE mode and goes out in PRGM mode.

     Rotation Direction Display Red lamp lights in DRIVE mode and goes out in PRGM mode.

     REMOTE Mode Red lamp lights when controlled by external terminal commands. SEQ: When RUN/STOP signal is selected from terminals. REF: When frequency reference is selected from terminals.

    Display

     Displays set value of each function or monitoring values such as frequency and output current. (5 digits)

     Mode Selection Key

     Depressing this key changes mode. (DRIVE or PRGM)

     Display Selection Key

     Depressing this key changes the display. See page 5 for explanation.

     Read/Write Key

    Depressing this key recalls and displays data from memory. Depressing it a second time enters display data into memory.

     Numeral Change Key Changes numeral such as set values and constant signals. : Increment key : Decrement key

     Digit Selection Key

     Selects numerical digits. Selected digit blinks. This key resets operation when fault occurs.

    Run Command Key 690-128

     Run Command Key to operate by digital operator. Effective only in drive mode.

     STOP command is input. (Motor stops in either mode.)* Red lamp lights by depressing STOP. *

     Selects FWD or REV run. Effective only in DRIVE mode.

    While depressing this key, JOG speed is selected. Effective only in DRIVE mode.

    2. DRIVE MODE AND PRGM (PROGRAM) MODE

     Selection of DRIVE mode or PRGM mode can be performed by using the key when the DRIVE

    inverter is stopped. When function selection or a change of set value is required, switch to the PRGM

    mode.

    ; Operation is enabled.

     RUN STOP ; An operation can be performed by

     DRIVE mode functions

    FWD keys.andJOG REV

     ; Frequency reference value or bn constants can be changed while running.

    ; Program (function selection, constant setting) can be changed. PRGM mode functions Note: Cannot be performed while running.

    ??????????For details of constants ( An- , bn- , Cn- , Sn- , Un- , refer to Section 7,

    “CONSTANTS/FUNCTION LIST.”

    2.2 CONSTANT GROUPS

    Constants of GA7200 are classified as follows:

    Constant Group Contents

    Frequency reference setting ??An-

    Constant group able to be changed while running ??bn-

    Constant, among control constant groups, related to operation ??Cn- change characteristics

    Constant, among system constant groups, to be used for ??Sn- function selection

The ability to set or read the different groups of constants is

    determined by Sn-03 as shown below.

    DRIVE Mode PRGM Mode

    Sn-03 Remarks

    Setting Reading Setting Reading

    0000 An, bn Sn, Cn An, bn, Sn, Cn Factory set

    0101 An bn, Sn, Cn An bn, Sn, Cn *

* It is recommended that Sn-03 be set to 0101 and reading mode entered after test run adjustment.

    Note: To read the Sn or Cn constants while in the DRIVE mode, depress the DSPL key with

     key depressed. RESET
