Maximum torque 2 /
uint32 Defines the source of the maximum torque limit for
the drive (in percent of nominal motor torque) when
• the source selected by parameter 30.25 Maximum
torque sel is 1, or
• 30.25 is set to Maximum torque 2 source .
See diagram at 30.18 Minimum torque sel .
Note: Any negative values received from the selected
source are inverted.

-300.0 % / real32 Defines the minimum torque limit for the drive (in
percent of nominal motor torque) when
• the source selected by parameter 30.18 Minimum
torque sel is 1, and
• 30.21 is set to PID .
Note: Do not set this parameter to 0% in an attempt
to prevent reverse rotation. In an open-loop application,
that is likely to prevent the motor from stopping
altogether. To prevent reverse rotation, use the
speed/frequency limits in this parameter group, or
