0.1…5.0 s
Maximum power failure duration.

Selects the motor start function for the scalar motor control
mode, ie. when
is set to
Notes:
• The start function for the DTC motor control mode is

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. 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 starts 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.

This setting should be used in applications where flying
