6. Parameter Management Functions
Several parameter management functions have been included with the option card. These functions are
accessed by setting all S1 switches off and using switch S2 to select the desired function, as summarized in
Table 2 below:
Function S1 Setting
(87654321)
S2 Setting
(654321)
Description
Save Parameter Settings ALL OFF 000001 This function saves the current parameter settings to the
option card.
Restore Parameter Settings ALL OFF 000010 This function restores the parameter settings to the values
saved in the option card.
Compare Parameter Settings ALL OFF 000100 This function compares the current parameter settings to
the values saved in the option card, displaying differences
on the digital operator.
Table 2. User Function Switch Settings
NOTE: These functions detect the current drive type (GPD505/GPD506) as well as that of the image
stored in the option card. If they differ, the functions will not complete and the ERROR LED
will be lit.
6.1 Save Parameters
This function saves the current parameters to the option card.
This feature may be particularly useful to users as a final step in their setup procedure. Once a drive has
been “fine-tuned” for a particular application, its unique setup can be saved for future use. A particular
setup may then be recalled when replacing a drive, copying to other drives, or restoring a setup that has
been altered.
To use this function, the following sequence should be observed:
1. Remove drive power.
2. Remove the network connection.
3. Select the desired function by setting switches S1 and S2 as described in Table 2.
4. Re-apply drive power.
5. Observe the RXD LED flashing. This occurs while the parameters are being read from the drive
and stops when this step is complete.
6. Observe the TXD LED flashing. This occurs while the parameters are being written to the option
card EEPROM and stops when this step is complete.
7. Upon successful completion of this function, the TXD LED remains on and all other LEDs should be
off.
8. Remove drive power.
9. Reset switches S1 and S2 to their usual settings.
10. Attach the network connection.
11. Re-apply drive power.
6.2 Restore Parameters
This function restores the parameters to the values saved in the option card.
With a unique drive setup already saved in the option card, this feature may be used when replacing a
drive, copying to other drives, or restoring a setup that has been altered.
