n 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.
No.
L3-06
<1> The upper limit and default for this setting is determined by C6-01 and L8-38.
n L7-01 to L7-04: Torque Limits
These parameters set the torque limits in each quadrant.
No.
L7-01
L7-02
L7-03
L7-04
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.
