194 Parameters
Continuous
magnetization
command
Activates/deactivates (or selects a source that
activates/deactivates) continuous magnetization. See
section
(page
The magnetization current is calculated on the basis of flux
reference (see parameter group
Notes:
• This function is only available when ramping is the
selected stop mode (see parameter
),
and only in speed control in DTC motor control mode
(see page
• Continuous magnetization causes the motor to heat up.
In applications where long magnetization times are
required, externally ventilated motors should be used.
• Continuous magnetization may not be able to prevent
the motor shaft from rotating during a long period if a
constant load is applied to the motor.
0 = Normal operation
1 = Magnetization active

Selects the way autophasing is performed.
See section
on page
Turning
This mode gives the most accurate autophasing result.
This mode can be used, and is recommended, if the motor
is allowed to rotate and the start-up is not time-critical.
Note: This mode will cause the motor to rotate. The load
torque must be less than 5%.
0
Standstill 1
Faster than the
mode, but not as accurate. The
motor will not rotate.
1
Standstill 2
An alternative standstill autophasing mode that can be
used if the
mode cannot be used, and the
mode gives erratic results. However, this mode
2
Turning with Z-pulse
This mode should be used if the zero pulse signal of the
pulse encoder is to be observed, and other modes do not
give a result. The motor will turn until a zero pulse is
detected.
3
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 pre-charging 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.
