148 Parameters
Automatic
Automatic start guarantees optimal motor start in most cases.
It includes the flying start function (starting into a rotating
motor) and the automatic restart function. The drive motor
control program identifies the flux as well as the mechanical
state of the motor and starts the motor instantly under all
conditions.
Note:
If parameter
is set to
,
no flying start or automatic restart is possible unless
parameter
is set to
2
Defines the pre-magnetization time when
• parameter
is set to
(in vector
motor control mode), or
• parameter
(in
scalar motor control mode).
After the start command, the drive automatically
premagnetizes the motor for the set time. To ensure full
magnetizing, set this parameter to the same value as, or
higher than, the rotor time constant. If not known, use the
rule-of-thumb value given in the table below:
Note:
This parameter cannot be changed while the drive is
running.
500 ms
0…10000 ms
Constant DC magnetizing time.
1 = 1 ms
Selects the way the motor is stopped when a stop command
is received.
Additional braking is possible by selecting flux braking (see
parameter
).
Coast
Stop by switching off the output semiconductors of the drive.
The motor coasts to a stop.
WARNING!
If a mechanical brake is used, ensure it is
safe to stop the drive by coasting.
0
Ramp
Stop along the active deceleration ramp. See parameter
group

.
1
Torque limit
Stop according to torque limits (parameters
).
This mode is only possible in vector motor control mode.
2
No.
