no : defaults are not loaded
Eur : 50Hz default parameters are loaded
USA
: 60Hz default parameters are loaded
Default parameters are set by pressing the MODE key on exit from parameter edit
mode after Pr 29 has been set to Eur or USA.
When default parameters have been set, the display will return to Pr 01 and Pr 10 will be
reset to L1.
0
: Fast ramp selected
1
: Standard ramp with normal motor voltage selected
2
: Standard ramp with high motor voltage selected
3 : Fast ramp with high motor voltage selected
Fast ramp is linear deceleration at programmed rate, normally used when a braking
resistor is installed.
Standard ramp is controlled deceleration to prevent DC bus over-voltage trips, normally
used when there is no braking resistor installed.
If a high motor voltage mode is selected, deceleration rates can be faster for a given
inertia but motor temperatures will be higher.
0 : Coast to stop selected
1 : Ramp to stop selected
2 : Ramp to stop with 1 second DC injection braking
3
: DC injection braking with detection of zero speed
4
: Time DC injection braking
OFF :Fixed linear voltage to frequency ratio (constant torque - standard load)
On
: Voltage to frequency ratio dependant on load current (dynamic/variable torque/
load). This gives a higher motor efficiency.
0
: Disabled
1
: Detect positive and negative frequencies
2 : Detect positive frequencies only
3
: Detect negative frequencies only
If the drive is to be configured in fixed boost mode (Pr 41 = Fd or SrE) with catch a
spinning motor software enabled, an autotune (see Pr 38 on page 62) must be carried
out to measure the motor’s stator resistance beforehand. If a stator resistance is not

The drive must be in a disabled, stopped or tripped condition to allow default parameters
to be set. If default parameters are set while the drive is running, the display will flash
FAIL once before changing back to no.
