3 Parameter x.00
Parameter x.00 is available in all menus and has the following functions.
*These functions do not require a drive reset to become active. All other
functions require a drive reset.
3.1 Parameter x.00 reset
When an action is started by setting Pr x.00 to one of the above values
and initiating a drive reset this parameter is cleared when the action is
completed successfully. If the action is not started, e.g. because the
drive is enabled and an attempt is made to load defaults, etc., Pr x.00 is
not cleared and no trip is produced. If the action is started and then fails
for some reason a trip is always produced and Pr x.00 is not cleared.
It should be noted that parameter saves etc. can also be initiated with
the copying parameter (Pr 11.42 (SE09, 0.30)). If actions that can be
initiated by either parameter are started and then completed
successfully Pr x.00 is cleared and Pr 11.42 (SE09, 0.30) is cleared if it
has a value of less than 3.
It should be noted that there could be some conflict between the actions
of Pr x.00 and Pr 11.42 (SE09, 0.30) Parameter copying when the drive
is reset. If Pr 11.42 (SE09, 0.30) has a value of 1 or 2 and a valid action
is required from the value of Pr x.00 then only the action required by
Pr x.00 is performed. Pr x.00 and Pr 11.42 (SE09, 0.30) are then reset to
zero. If Pr 11.42 (SE09, 0.30) has a value of 3 or 4 it will operate
correctly causing parameters to be save to a SMARTCARD each time a
parameter save is performed.
3.2 Saving parameters in drive EEPROM
Drive parameters are saved to drive EEPROM by setting Pr x.00 to save
and initiating a drive reset. In addition to user save parameters. power
down save parameters are also saved by these actions and by changing
drive mode, but not by any other actions that result in parameters being
saved to drive EEPROM (i.e. loading defaults). Power down save
parameters are not saved at power down unless the drive is supplied
from a normal line power supply, and so this gives the user the option of
saving these parameters when required.
When the parameter save is complete Pr x.00 is reset to zero by the
drive. Care should be taken when saving parameters because this
action can take between 400 ms and several seconds depending on
how many changes are stored in the EEPROM. If the drive is powered
down during a parameter save, it is possible that data may be lost.
When the drive is operating from a normal line power supply then it will
stay active for a short time after the power is removed, however, if the
drive is being powered from a 24 V control supply, or it is being operated
from a low voltage battery supply, the drive will power down very quickly
after the supply is removed. The drive provides two features to reduce
the risk of data loss when the drive is powered down.
1. If Pr x.00 is set to save a parameter save is only initiated on drive
reset if the drive is supplied from a normal line power supply
(Pr 10.16 = 0 and Pr 6.44 = 0).
2. Two banks of arrays are provided in EEPROM to store the data.
When a parameter save is initiated the data is stored in a new bank
and only when the data store is complete does the new bank
become active. If the power is removed before the parameter save is
complete a SAVE.Er trip (user save parameter save error) or
PSAVE.Er trip (power down save parameter save error) will be
produced when the drive is powered up again indicating that the
drive has reverted to the data that was saved prior to the last
parameter save.
The second feature will significantly reduce the possibility of completely
invalidating all saved data, which would result in an EEF trip on the next
power-up. However the following points should be noted:
1. If the power is removed during a parameter save the current data
that is being saved to the EEPROM that is different from the last
data saved in the EEPROM will be lost and SAVE.Er or PSAVE.Er
trip will occur on power-up.
2. This feature does not apply when user save parameters are saved
automatically by adjusting the values in menu 0 with an LED keypad.
However, the time taken to save parameters in this way is very short,
and is unlikely to cause data loss if the power is removed after the
parameter has been changed. It should be noted that any parameter
changes made in this way are included in the currently active bank in
the EEPROM, so that if the power is removed during a subsequent
save initiated via Pr x.00 that results in an SAVE.Er trip, the changes
made via menu 0 will be retained and not lost.
3. User save parameters are saved to drive EEPROM after a transfer
of data from an electronic nameplate in an encoder.
4. User save parameters are saved to drive EEPROM after a transfer
of data from a SMARTCARD.
5. This feature is not provided for data saved to a SMARTCARD, and
so it is possible to corrupt the data files on a SMARTCARD if the
power is removed when data is being transferred to the card.
6. User save parameters are saved to drive EEPROM after defaults
are loaded.
