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
cloning parameter (Pr 11.42). If actions that can be initiated by either
parameter are started and then completed successfully Pr x.00 is
cleared and Pr 11.42 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 (Parameter cloning) when the drive is reset. If
Pr 11.42 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 are then reset to zero. If Pr 11.42 has a value of 3
or 4 it will operate correctly causing parameters to be save to a smart
card 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 mains 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 400ms
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 mains supply then it will stay active for a short time after the
power is removed, however, if the drive is being powered from a 24V
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 mains 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
Serial comms
