The motor can be automatically started after a short
supply power failure using the automatic restart
function. See section
When this parameter is set to 0.0 seconds, automatic
restarting is disabled. Otherwise, the parameter defines
the maximum duration of the power failure after which
restarting is attempted. Note that this time also
includes the DC precharging delay.
WARNING!
The function restarts the drive automatically
and continues operation after a supply break.
Make sure that no dangerous situations can
occur.

The drive pre-magnetizes the motor before start. The
premagnetizing time is defined by parameter
. This mode should be selected if
constant pre-magnetizing time is required (e.g. if the
motor start must be synchronized with the release of
a mechanical brake). This setting also guarantees the
highest possible break-away torque when the
pre-magnetizing time is set long enough.
Note: This mode cannot be used to start into a rotating
motor.
WARNING!
The drive will start after the set magnetizing
time has passed even if motor magnetization
is not completed. In applications where a full
break-away torque is essential, ensure that the
constant magnetizing time is long enough to
allow generation of full magnetization and
torque.
