Other [bit] Source selection (see Terms and abbreviations on page 100). -
21.16 Pre-heating current Defines the DC current used to heat the motor. The value is in
percent of the nominal motor current.
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 (page 81).
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
precharging delay. See also parameter 21.34 Force auto
restart.
This parameter has effect only if parameter 95.04 Control
board supply is set to External 24V.
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.
10.0 s
0.0 s Automatic restarting 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 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 (page 76).
Automatic
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 pre-
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.
