268 Parameters
30.23 Minimum torque 2 Defines 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, and
• 30.21 is set to Minimum torque 2 .
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 .
See diagram at 30.18 Minimum torque sel .

30.24 Maximum torque 2 Defines the maximum torque limit for the drive (in percent of
nominal motor torque) when
• the source selected by parameter
30.25 Maximum torque
sel is 1, and
• 30.22 is set to Maximum torque 2 .
See diagram at 30.18 Minimum torque sel .

30.25 Maximum torque
sel Selects a source that switches between two different
maximum torque limits.
0 = Maximum torque limit 1 defined by
30.20 is active
1 = Maximum torque limit selected by 30.22 is active

30.26 Power motoring
limit Defines the maximum shaft power in motoring mode, ie. when
power is being transferred from the motor to the machinery.
The value is given in percent of nominal motor power. 300.00%
0.00 … 600.00% Maximum shaft power in motoring mode. 1 = 1%
30.27 Power generating
limit Defines the maximum shaft power in generating mode, ie.
when power is being transferred from the machinery to the
motor. The value is given in percent of nominal motor power.
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
