7.5.2 Display messages
The following tables indicate the various possible mnemonics which can
be displayed by the drive and their meaning.
Trip types are not listed here but can be found in Chapter 8

7.6 Changing the operating mode
Changing the operating mode returns all parameters to their default
value, including the motor parameters. (Pr
0.49
Security status
and Pr
0.34
User security code
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 31 is open or Pr
6.15
is
Off (0)
2. Enter either of the following values in Pr
xx.00
, as appropriate:
1253 (EUR, 50Hz AC supply frequency)
1254 (USA, 60Hz AC supply frequency)
3. Change the setting of Pr
0.48
as follows:
The figures in the second column apply when serial communications are
used.
4. Either:
•
Press the red
reset button
•
Toggle the reset digital input
•
Carry out a drive reset through serial communications by setting
Pr
10.38
to 100 (ensure that Pr.
xx.00
returns to 0).
Entering 1253 or 1254 in Pr
xx.00
will only load defaults if the setting of
Pr
0.48
has been changed.
7.7 Saving parameters
When changing a parameter in Menu 0, the new value is saved when
pressing the
Mode 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
Enter 1000* in Pr.
xx.00
Either:
•
Press the red
reset button
•
Toggle the reset digital input
•
Carry out a drive reset through serial communications by setting
Pr
10.38
to 100 (ensure that Pr.
xx.00
returns to 0).
*If the drive is in the under voltage trip state or is being supplied from a
low voltage DC supply, a value of 1001 must be entered into Pr
xx.00
to
perform a save function.
7.8 Restoring parameter defaults
Restoring parameter defaults by this method saves the default values in
the drive’s memory. (Pr
0.49
and Pr
0.34
are not affected by this
procedure.)
Procedure
1. Ensure the drive is not enabled, i.e. terminal 31 is open or Pr
6.15
is
Off (0)
2. Enter 1233 (EUR 50Hz settings) or 1244 (USA 60Hz settings) in
Pr
xx.00
.

Description
br.rS
Braking resistor overload
Braking resistor I
2
t accumulator (Pr
10.37
) in the drive has reached
75.0% of the value at which the drive will trip and the braking IGBT is
active.
Hot
Heatsink or control board or inverter IGBT over
temperature alarms are active
•
The drive heatsink temperature has reached a threshold and the
drive will trip ‘Oh2’ if the temperature continues to rise (see the
‘Oh2’ trip).
or
•
The ambient temperature around the control PCB is approaching
the over temperature threshold (see the ‘O.CtL’ trip).
OVLd
Motor overload
The motor I
2
t accumulator in the drive has reached 75% of the value at
which the drive will be tripped and the load on the drive is >100%
Auto tune
Autotune in progress
The autotune procedure has been initialised. 'Auto' and 'tunE' will flash
alternatively on the display.
Lt
Limit switch is active
Indicates that a limit switch is active and that it is causing the motor to
be stopped (i.e. forward limit switch with forward reference etc.)
PLC
Onboard PLC program is running
An Onboard PLC program is installed and running. The lower display
will flash 'PLC' once every 10s.

Description
boot
A parameter set is being transferred from the SMARTCARD to the
drive during power-up. For further information, please refer to section
11.2.4
Booting up from the SMARTCARD on every power up (Pr 11.42
= boot (4))
on page 151.
cArd
The drive is writing a parameter set to the SMARTCARD during power-
up.
