System parameters affecting individual axes 3. System parameters affecting overall operation (including communication) plus accessory and option settings. The current variables are the operating values that are displayed and affected by the front panel keys.

  • Page 24: Display Operation

    REFERENCE DISPLAY OPERATION The QC-1000 is a digital measuring device that displays measurements corresponding to the movement of a machine table equipped with one or more encoders. For linear measuring the display shows a maximum measurement of seven digits the actual measurement will depend on the resolution of the encoders. There are seven active digits, the eighth, the left-most, is reserved for a minus sign (-) when used.

  • Page 25: Display Resolution

    REFERENCE The unit shows INCH and INCR at initial power-up with current measuring choices indicated in message areas at the bottom of each display. Corresponding messages change each time the INCR/ABS key is pressed. Subsequent power-up messages are the result of changes to parameters. Encoder Reference Arming is indicated by a lighted message area in all displays.

  • Page 26: Display Zeroing

    REFERENCE DISPLAY ZEROING Display Zeroing is a "current" mode operation. The displays must be zeroed periodically to enable a new measurement sequence. The ABS and INCR measuring modes display independent measurements and are zeroed independently. Each axis may be zeroed at any time by pressing its ZERO key. The display can only be zeroed in the current measuring mode.

  • Page 27: Display Modifying Counter Charactieristics

    REFERENCE DISPLAY MODIFYING COUNTER CHARACTIERISTICS Error Compensation Error compensation is provided with a know linear single-value compensation to correct Abbe error and machine wear problems. Error compensation is accomplished by adding or subtracting counting pulses. Error compensation applies to either linear or angular measuring axis. For an angular axis, error compensation should be used only when maximum rotations are less than one full revolution because the encoder must return to the same point each full revolution and does not require compensation.

  • Page 28: Encoder Error Indication And Recovery

    MULTIPLE ENCODER RESOLUTION All currently available resolutions for standard Acu-Rite digital signal encoders plus common angular (rotary) encoders are supported. Heidenhain analog signal encoders using optional signal-processing circuitry are also supported. All axes resolutions are factory set to 2um (linear encoders) and may be changed as part of the set up program.

  • Page 29: Prescale Factor

    REFERENCE PRESCALE FACTOR A scale factor is provided for encoders with odd resolutions. This factor is applicable to a linear measuring system which has a rotary encoder and an odd pitched lead screw, neither of which can be independently measured. The mounting table movement can be measured and resulting display compared to determine the resolution.

  • Page 30: Print Key

    REFERENCE LINEAR ERROR COMPENSATION(CONTD) Note that with the entry method no prior compensation factor setting should be set. Prior settings for the actual and observed measurements are shown as they are observed. This is because the operator is instructed to enter measurements while the internal representation for the compensation factor is a PPM error.

  • Page 31: Selt-Test

    REFERENCE SELT-TEST A self-test routine is available as a setup menu selection. These tests perform a keyboard test and internal circuitry check. None of the display message areas are lit during testing. The repeating test consists of checking the operation of the ICs in each axis, returning to the top axis and repeating the test.

  • Page 32: Numeric Entry

    REFERENCE NUMERIC ENTRY Numeric Entry is an item in the setup menu provided for number entry during setup. If the number is an axis-specific parameter it will be shown in that axis display.
