Code Modbus ID Parameter Application RO/RW
P6.1.8 314 Stall Current Limit 1,2,3 RW
This parameter is used to set the current level when above the unit will stall. For a stall stage to
occur, the current must have exceeded this limit. The software does not allow entering a greater value
than In-Motor*2. If nominal motor current is changed, this parameter is automatically restored to the
default value (IL).

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).
