Parameters 267
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
Minimum torque sel.
The limit is effective when
• the source selected by 30.18 Minimum torque sel is 0, or
• 30.18 is set to Minimum torque 1.
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.

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
Minimum torque sel.
The limit is effective when
• the source selected by 30.25 Maximum torque sel is 0, or
• 30.25 is set to Maximum torque 1.

30.21 Minimum 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 Minimum torque
sel is 1, or
• 30.18 is set to Minimum torque 2 source.
See diagram at 30.18 Minimum torque sel.
Note: Any positive values received from the selected source
are inverted.
