Issue Number: 1
5.5 Advanced menus
The advanced menus consist of groups or parameters appropriate to a
specific function or feature of the drive. Menus 0 to 22 can be viewed on
the Keypad.
Table 5-4 Advanced menu descriptions
5.5.1 Display messages
The following tables indicate the various possible mnemonics which can
be displayed by the drive and their meaning.
Table 5-5 Status indications
5.5.2 Alarm indications
An alarm is an indication given on the display by alternating the alarm
string with the drive status string on the display. Alarms strings are not
displayed when a parameter is being edited.
Table 5-6 Alarm indications
5.6 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'* in Pr mm.000 (alternatively enter a value of 1000* in
Pr mm.000)
2. Either:
• Press the red reset button
* If the drive is in the under voltage state (i.e. when the AI-Backup
adaptor terminals 1 & 2 are being supplied from a +24 V DC supply) a
value of 1001 must be entered into Pr mm.000 to perform a save
function.
5.7 Restoring parameter defaults
Restoring parameter defaults by this method saves the default values in
the drives memory. User security status (00.010) and User security code
(00.025) are not affected by this procedure).
Procedure
1. Ensure the drive is not enabled, i.e. terminal 11 is open or Pr 06.015
is OFF (0)
2. Select 'Def.50’ or 'Def.60' in Pr mm.000. (alternatively, enter 1233
(50 Hz settings) or 1244 (60 Hz settings) in Pr mm.000).
3. Either:
• Press the red reset button

String Description
Drive
output
stage
inh
The drive is inhibited and cannot be run.
The Drive Enable signal is not applied to
the drive enable terminal or Pr 06.015 is
set to 0. The other conditions that can
prevent the drive from enabling are shown
as bits in Enable Conditions (06.010)
Disabled
rdy
The drive is ready to run. The drive enable
is active, but the drive inverter is not active
because the final drive run is not active
Disabled
StoP The drive is stopped / holding zero speed. Enabled
AC Supply loss condition has been detected Enabled
dECEL
The motor is being decelerated to zero
speed / frequency because the final drive
run has been deactivated.
Enabled
dc inj The drive is applying dc injection braking Enabled
Er
The drive has tripped and no longer
controlling the motor. The trip code
appears on the display.
Disabled
UV
The drive is in the under voltage state
either in low voltage or high voltage mode.
Disabled
Alarm string Description
br.res
Brake resistor overload. Braking Resistor Thermal
Accumulator (10.039) in the drive has reached 75.0
% of the value at which the drive will trip.
OV.Ld
Motor Protection Accumulator (04.019) in the drive
has reached 75.0 % of the value at which the drive
will trip and the load on the drive is >100 %.
d.OV.Ld
Drive over temperature. Percentage Of Drive
Thermal Trip Level (07.036) in the drive is greater
than 90 %.
tuning
The autotune procedure has been initialized and an
autotune in progress.
LS
Limit switch active. Indicates that a limit switch is
active and that is causing the motor to be stopped.
Lo.AC Low voltage mode. See Low AC Alarm (10.107).
I.AC.Lt
Current limit active. See Current Limit Active
(10.009).
