Note: Set this parameter to 0 to improve the response at the rapid
addition and subtraction velocity at start.

Defines the behavior of the regenerative torque limits.
0: Standard mode – Torque Limit is affected by all analog and communication
Torque Limit settings.
1: Independent mode – Only L7-03, L7-04 and Regen Torque Limit analog
input setting affect the regenerative quadrants.
All Modes
An overheat alarm occurs when heatsink temperature exceeds the L8-02 level.
All Modes
0: Ramp to stop. A fault is triggered.
1: Coast to stop. A fault is triggered.
2: Fast Stop. Decelerate to stop using the deceleration time in C1-09. A fault
is triggered.
3: Continue operation. An alarm is triggered.
4: Continue operation at reduced speed as set in L8-19.
All Modes
Selects the detection of input current phase loss, power supply voltage
imbalance, or main circuit electrolytic capacitor deterioration.
0: Disabled
1: Enabled
All Modes
0: Disabled
1: Enabled (triggered by a single phase loss)
2: Enabled (triggered when two phases are lost)
All Modes
0: Disabled
1: Enabled
All Modes
0: During run only. Fan operates only during run for L8-11 seconds after stop.
1: Fan always on. Cooling fan operates whenever the drive is powered up.
All Modes
Sets a delay time to shut off the cooling fan after the Run command is removed
when L8-10 = 0.
All Modes
Enter the ambient temperature. This value adjusts the oL2 detection level.
All Modes
0: No oL2 level reduction below 6 Hz.
1: oL2 level is reduced linearly below 6 Hz. It is halved at 0 Hz.
