2020 BRAKE
CHOPPER
Selects the brake chopper control.
When using the drive in a Common DC bus system, the
parameter must be set to EXTERNAL. When in Common
DC, the drive cannot feed or receive more power than P
N
.
INBUILT
INBUILT Internal brake chopper control.
Note: Ensure the brake resistor(s) is installed and the
overvoltage control is switched off by setting parameter
2005 OVERVOLT CTRL to selection DISABLE. See also
2005 OVERVOLT CTRL selection EN WITH BRCH.
0
EXTERNAL External brake chopper control.
Note: The drive is compatible only with ABB ACS-BRK-X
brake units.
Note: Ensure the brake unit is installed and the overvoltage
control is switched off by setting parameter 2005
OVERVOLT CTRL to selection DISABLE.

FUNCTION
Selects the motor starting method. AUTO
AUTO The drive starts the motor instantly from zero frequency if
parameter 9904 MOTOR CTRL MODE setting is SCALAR:
FREQ. If flying start is required use selection SCAN START.
If parameter 9904 MOTOR CTRL MODE value is VECTOR:
SPEED or VECTOR: TORQ, the drive pre-magnetizes the
motor with DC current before the start. The pre-magnetizing
time is defined by parameter 2103 DC MAGN TIME. See
selection DC MAGN.
For permanent magnet synchronous motors, flying start is
used if the motor is rotating.
