Parameters 267
Defines a minimum torque limit for the drive (in percent of
nominal motor torque). See diagram at parameter
.
The limit is effective when
• the source selected by
is 0, or

is set to
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
.
