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 .
-300.0%
-1600.0 … 0.0% Minimum torque limit 1. See par.
46.03
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 .
300.0%
0.0 … 1600.0% Maximum torque 1. See par.

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.
