COMM Fieldbus interface as the source for the torque limit 1/2
selection, ie control word 0301 FB CMD WORD 1 bit 15.
The control word is sent by the fieldbus controller through
the fieldbus adapter or embedded fieldbus (Modbus) to the
drive. For the control word bits, see section DCU
communication profile on page 320.
Maximum torque limit 1 is defined by parameter 2017 MAX
TORQUE 1 and maximum torque limit 2 is defined by
parameter 2018 MAX TORQUE 2.
Note: This setting applies only for the DCU profile.

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.
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.
