Description
Selects the enable signal warnings that will be
suppressed. This parameter can be used to prevent
these warnings from being added to the event log.
Whenever a bit of this parameter is set to 1, the
corresponding warning is suppressed.

Notes:
• The start function for the scalar motor control
mode is selected by parameter

.
• Starting into a rotating motor is not possible when
DC magnetizing is selected (
• With permanent magnet motors,
mode must be used.
• This parameter cannot be changed while the drive
is running.
DC magnetization

The drive pre-magnetizes the motor before start. The
pre-magnetizing time is determined automatically,
typically 200 ms to 2 s depending on motor size.
Select this mode if a high break-away torque is
required.
The drive pre-magnetizes the motor before start. The
pre-magnetizing time is defined by parameter
Magnetization time
. 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.
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.
