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.
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 option
card EEPROM stops when this step is complete.
6. Observe the TXD LED flashing. This occurs while the parameters are being written to the drive
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. If any errors occurred, the ERROR LED will be flashing. Monitor U-11 is used to display
the data which failed to be written. The parameter number is displayed first, as ‘1xxx’, where
‘xxx’ is the parameter number. The next value displayed is the value which failed to be written.
The list of failed parameters is displayed repeatedly until power is removed.
8. Remove drive power.
9. Reset switches S1 and S2 to their usual settings.
10. Attach the network connection.
11. Re-apply drive power.
6.3 Compare Parameters
This function compares the current parameters to the values saved in the option card, displaying
differences on the digital operator.
With a unique drive setup already saved in the option card, this feature may be used to evaluate which
parameters have been changed since the setup was saved. This may be particularly useful in
summarizing parameter changes during a troubleshooting process or determining what changes have
been made since a drive’s initial installation.
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
stops when this step is complete.
6. Observe the TXD LED flashing. This occurs while the current parameter settings are being
compared to the values stored in 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 if no differences exist. If there are any differences, the ERROR LED will be flashing.
Monitor U-11 is used to display the data which is different. The parameter number is displayed
first, as ‘1xxx’, where ‘xxx’ is the parameter number. The next value displayed is the value stored
in the option card EEPROM. These values can be recorded and compared to the current drive
settings. The list of differences is displayed repeatedly until power is removed.
8. Remove drive power.
9. Reset switches S1 and S2 to their usual settings.
10. Attach the network connection.
11. Re-apply drive power.
