P9.15 317 Underload Protection 1, 2, 3, 4 RW
If tripping is set active, the drive will stop and activate the fault stage. Deactivating
the protection by setting the parameter to zero will reset the underload time counter
to zero.
0 No response
1 Warning
2 Fault, stop mode after fault according to P7.10
3 Fault, stop mode after fault always by coasting
P9.16 318 Underload Fnom Torque 1, 2, 3, 4 RW
The torque limit can be set between 10.0–150.0% x T
n
Motor.
This parameter gives the value for the minimum torque allowed when the output
frequency is above the field weakening point. See Figure 62.
If you change P1.5, nominal motor current, this parameter is automatically restored
to the default value.

P9.17 319 Underload F0 Torque 1, 2, 3, 4 RW
The torque limit can be set between 5.0–150.0% x T
n
Motor.
This parameter gives value for the minimum torque allowed with zero frequency.
See Figure 63.
If you change the value of P1.5, nominal motor current, this parameter is
automatically restored to the default value.
