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
: Timed DC injection braking
Before the SmartStick is written to using Prog, the SmartStick will need to be inserted
into the drive at power up or a reset command performed when the drive has been
powered up, otherwise will trip on C.dAt when Prog command executed.
For best motor performance, an autotune should be carried out after parameter copying
has taken place.
When copying between drives of different ratings, bit parameters will not be copied.

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.
NOTE
Disconnect the electro-mechanical brake circuit before a default is performed.
