EFB Only for the DCU profile. DCU control word bit 15 received
through the embedded fieldbus interface.

Other [bit] Source selection (see Terms and abbreviations). -
30.19 Minimum torque 1 Defines a minimum torque limit for the drive (in percent of
nominal motor torque). See diagram at parameter 30.18
Torq lim sel.
The limit is effective when
• the source selected by 30.18 Torq lim sel is 0, or
• 30.18 is set to Torque limit set 1.
WARNING! Do not use minimum torque to stop
reverse rotation of the motor. Usage of minimum
torque limits disables the drive to reach zero speed
and fails to stop the motor.
-300.0%
-1600.0…0.0% Minimum torque limit 1. See par.

30.20 Maximum torque 1 Defines a maximum torque limit for the drive (in percent of
nominal motor torque). See diagram at parameter 30.18
Torq lim sel.
The limit is effective when
• the source selected by 30.18 Torq lim sel is 0, or
• 30.18 is set to Torque limit set 1.

30.21 Min torque 2 source Defines the source of the minimum torque limit for the
drive (in percent of nominal motor torque) when
• the source selected by parameter 30.18 Torq lim sel is
1, or
• 30.18 is set to Torque limit set 2.
See diagram at 30.18 Torq lim sel.
Note: Any positive values received from the selected
source are inverted.
