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

30.24 Maximum torque
See Terms and abbreviations (page
Defines the minimum torque limit for the drive (in
percent of nominal motor torque) when
• the source selected by parameter
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
parameters 20.23/20.24.
