Table 62. Protections (Cont.).
Underload protection
P6.1.10 ab
Minimum value: N.A.
Options: 0 = No response;
1 = Warning;
2 = Fault - stop mode after fault according to parameter stop mode; or
3 = Fault - stop mode after fault always by coasting.
Description: If fault is set as the function, the drive will stop and activate the fault stage based on the parameter conditions and the monitoring
status of the motor. If the motor torque drops below the Fnom and F0, torque levels for the time limit the protection is enabled.
Deactivating the protection by setting the parameter to 0 will reset the underload time counter to zero.
Underload Fnom torque
P6.1.11 ab
Minimum value: 10.0%
The torque limit can be set between 10.0 - 150.0 % x TnMotor. This parameter gives the value for the minimum torque allowed when
Description:
the output frequency is at or above the field weakening point. If you change P1.6, nominal motor current, this parameter is automatically
restored to the default value.
Underload F0 torque
P6.1.12 b
5.0%
Minimum value:
Description: The torque limit can be set between 5.00 - 150.00% x TnMotor. This parameter gives value for the minimum torque allowed at zero
frequency. If you change the value of P1.6, nominal motor current, this parameter is automatically restored to the default value.
