5.7 Changing the operating mode
Changing the operating mode returns all parameters to their default
value, including the motor parameters.
Procedure
Use the following procedure only if a different operating mode is
required:
1. Enter either of the following values in Pr
0.00 , as appropriate:
1253 (Europe, 50Hz AC supply frequency)
1254 (USA, 60Hz AC supply frequency)
2. Change the setting of Pr 0.48 as follows:
The figures in the second column apply when serial communications are
used.
3. Press or momentarily close the RESET contact.
The new setting takes effect and all the parameters revert to the
appropriate default values for the new mode.
5.8 Saving parameters
Procedure
Enter 1000 in Pr xx.00
Press the red reset button or toggle the reset digital input
(ensure Pr
xx.00 returns to 0)
5.9 Defaulting the drive
Procedure
Enter 1233 (EUR 50 Hz settings) or 1244 (USA 60 Hz settings) in
Pr
xx.00
Press the red reset button or toggle the reset digital input (ensure
Pr
xx.00 returns to 0)

Conditions
Drive output
stage
Act Regeneration mode active
Enabled
Regen mode> The Regen drive is enabled and
synchronised to the supply.
ACUU AC Supply loss
Enabled
The drive has detected that the AC supply has been
lost and is attempting to maintain the
DC
bus voltage
by decelerating the motor.
dc DC applied to the motor
Enabled
The drive is applying
DC
injection braking.
dEC Decelerating
Enabled
The drive is decelerating the motor.
inh
Inhibit
Disabled
The drive is inhibited and cannot be run.
Drive enable signal not applied to terminal 30 or Pr
6.15 is set to 0.
POS Positioning
Enabled
The drive is positioning/orientating the motor shaft.
rdY Ready
Disabled
The drive is ready to be run.

Running
Enabled
The drive is running.
SCAn Scanning
Enabled
OL> The drive is searching for the motor frequency
when synchronising to a spinning motor.
Regen> The drive is enabled and is synchronising to
the line.
StoP Stop or holding zero speed
Enabled
The drive is holding the motor at zero speed.
Regen> The drive is enabled but the AC voltage is too
low, or DC Bus voltage still rising or falling.
triP Trip condition
Disabled
The drive has tripped and is no longer controlling the
motor. The trip code appears on the upper display.

Conditions
Air Control PCB ambient temperature near maximum limit
The ambient temperature around the control PCB has reached 90
°
C
(194
°
F) and the drive will trip OA if the temperature continues to rise
(see the OA trip).
br.rS Braking resistor overload
The braking-resistor [I x t] accumulator in the drive has reached 75%
of the value at which the drive will be tripped.
hot
Heatsink temperature near maximum limit
The drive heatsink has reached 90
°
C (194
°
F) and the drive will trip
Oh2 if the temperature continues to rise (see the Oh2 trip).
OVLd Motor overload
The motor [I x t] accumulator in the drive has reached 75% of the value
at which the drive will be tripped.
