L3-06: Stall Prevention Level during Run
Sets the current level to trigger Stall Prevention during run. Depending on the setting of parameter L3-23, the level is
automatically reduced in the constant power range (speed beyond base speed). A setting of 100% is equal to the drive rated
current.
The Stall Prevention level can be adjusted using an analog input.

L7-01 to L7-04: Torque Limits
These parameters set the torque limits in each quadrant.
No. Name Setting Range Default
L7-01 Forward Torque Limit 0 to 300% 200%
L7-02 Reverse Torque Limit 0 to 300% 200%
L7-03 Forward Regenerative Torque Limit 0 to 300% 200%
L7-04 Reverse Regenerative Torque Limit 0 to 300% 200%
Note: If the multi-function analog input is programmed for “10: Forward torque limit”, “11: Reverse torque limit”, “12: Regenerative torque
limit”, or “15: General torque limit”, the drive uses the lowest value from L7-01 through L7-04, or analog input torque limit.
