5.5.3 Alarm indications
An alarm is an indication given on the display by alternating the alarm
string with the drive status string on the upper row and showing the
alarm symbol in the last character in the upper row. Alarms strings are
not displayed when a parameter is being edited, but the user will still see
the alarm character on the upper row.

indications at power-up
5.6 Changing the operating mode
Changing the operating mode returns all parameters to their default
value, including the motor parameters. User security status (00.031) and
User security code (00.030) are not affected by this procedure).
Procedure
Use the following procedure only if a different operating mode is
required:
1. Ensure the drive is not enabled, i.e. terminal 29 is open or Pr 06.015
is OFF (0)
2. Enter either of the following values in Pr mm.000, as appropriate:
1253 (50 Hz AC supply frequency)
1254 (60 Hz AC supply frequency)
3. Change the setting of Pr 00.030 to L2 to allow access to Pr 11.031
4. Change the setting of Pr 11.031 as follows:
The figures in the second column apply when serial communications are
used.
5. Either:
• Press the red reset button
• Toggle the reset digital input
• Carry out a drive reset through serial communications by setting
Pr 10.038 to 100.
Entering 1253 or 1254 in Pr mm.000 will only load defaults if the setting
of Pr 11.031 has been changed.
5.7 Saving parameters
When changing a parameter in Menu 0, the new value is saved when
pressing the Enter button to return to parameter view mode from
parameter edit mode.
If parameters have been changed in the advanced menus, then the
change will not be saved automatically. A save function must be carried
out.
Procedure
1. Select ‘Save Parameters' in Pr mm.000 (alternatively enter a value
of 1001 in Pr mm.000)
2. Either:
• Press the red reset button
• Toggle the reset digital input, or
• Carry out a drive reset through serial communications by setting
Pr 10.038 to 100

Writing To NV Card
Data being written to NV Media
Card
Data is being written to a NV Media Card to ensure that its copy of the
drive parameters is correct because the drive is in Auto or Boot mode
Waiting For Power System Waiting for power stage
The drive is waiting for the processor in the power stage to respond
after power-up
Waiting For Options Waiting for an option module
The drive is waiting for the options modules to respond after power-up
Uploading
From
Options Loading parameter database
At power-up it may be necessary to update the parameter database
held by the drive because an option module has changed or because
an applications module has requested changes to the parameter
structure. This may involve data transfer between the drive an option
modules. During this period ‘Uploading From Options’ is displayed
