.
Notes
:
• The start function for the scalar motor control
• Starting into a rotating motor is not possible
when DC magnetizing is selected (
).
• With permanent magnet motors,
start mode must be used.
• This parameter cannot be changed while the
drive is running.
Fast
The drive pre-magnetizes the motor before start.
The pre-magnetizing time is determined
automatically, being typically 200 ms to 2 s
depending on motor size. This mode should be
selected if a high break-away torque is required.
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.
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.
