Other [bit] Source selection (see Terms and abbreviations). -
21.16 Pre-heating current Defines the DC current used to heat motor findings. 0.0%
0.0…30.0% Pre-heating current. 1 = 1%
21.18 Auto restart time The motor can be automatically started after a short
supply power failure using the automatic restart function.
See section Automatic restart on page 85.
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.
00.0 s
0.0 s Automatic restart disabled. 0
0.1…10.0 s Maximum power failure duration. 1 = 1 s
21.19 Scalar start mode Selects the motor start function for the scalar motor
control mode, ie. when 99.04 Motor control mode is set to
Scalar.
Notes:
• The start function for the vector motor control mode is
selected by parameter 21.01 Vector start mode.
• With permanent magnet motors, Automatic start mode
must be used.
• This parameter cannot be changed while the drive is
running.
See also section DC magnetization on page 72.
Const time
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 21.02
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.
Note: This mode cannot be used to start into a rotating
motor.
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.
