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

Source selection (see Terms and abbreviations
152).
Defines the source of the maximum torque limit for the drive
(in percent of nominal motor torque) when
• the source selected by parameter
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.
