Defines a minimum torque limit for the drive (in percent
of nominal motor torque). See diagram at parameter
30.18 Minimum torque
The limit is effective when
• the source selected by
is 0, or
• 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. For scaling, see parameter
46.3.
Defines a maximum torque limit for the drive (in
percent of nominal motor torque). See diagram at
parameter 30.18 Minimum torque
The limit is effective when
• the source selected by
is 0, or
• 30.25 is set to Maximum torque
Maximum torque 1. For scaling, see parameter 46.3.
Defines the source of the minimum torque limit for the
drive (in percent of nominal motor torque) when
• the source selected by parameter
torque sel is 1, or
• 30.18 is set to Minimum torque 2 source
See diagram at 30.18 Minimum torque

source are inverted.
