Code Modbus ID Parameter Application RO/RW
P6.1.9 315 Stall Time Limit 1,2,3 RW
This parameter is used to set the time limit before a stall error occurs.
The stall time is counted by an internal up/down counter based off the current being above the
limit setting. If the stall time counter value goes above this limit the protection will cause a trip
(see Para ID313).

P6.1.10 316 Stall Frequency Limit 1,2,3 RW
This parameter is used to set the frequency level where below it a stall condition and is above the current
limit for the stall time to occur.
P6.1.11 317 Underload Protection 1,2,3 RW
This parameter is used to set the device reaction to an “UnderLoad Motor” condition. Deactivating the
protection by setting the parameter to 0 will reset the underload time counter to zero.
0 = No response
1 = Warning
2 = Fault, stop mode after fault according to standard stop mode
3 = Fault, stop mode after fault always by coasting
P6.1.12 318 Underload Fnom Torque 1,2,3 RW
This parameter gives the value for the minimum torque allowed when the output frequency is at or above
the field weakening point. If you change Para ID486, nominal motor current, this parameter is automatically
restored to the default value.
