Defines the DC current used to heat the motor. The value is in
percent of the nominal motor current.

The motor can be automatically started after a short supply
power failure using the automatic restart function. See section
(page
).
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!
Before you activate the function, make
sure that no dangerous situations can occur. The
function restarts the drive automatically and continues
operation after a supply break.

Selects the motor start function for the scalar motor control
mode, ie. when
is set to

Notes
:
• The start function for the vector motor control mode is
• With permanent magnet motors,
start mode
must be used.
• This parameter cannot be changed while the drive is
running.

Normal
Immediate start from zero speed.
0
Const time
The drive pre-magnetizes the motor before start. The pre-
magnetizing 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 pre-
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.
1
Automatic
The drive automatically selects the correct output frequency
to start a rotating motor. This is useful for flying starts: if the
motor is already rotating, the drive will start smoothly at the
current frequency.
Note:
Cannot be used in multimotor systems.
