0: Disabled
1: oL4 detection only active during speed agree, operation continues after
detection
2: oL4 detection always active during run, operation continues after detection
3: oL4 detection only active during speed agree, output shuts down on an oL4
fault
4: oL4 detection always active during run, output shuts down on an oL4 fault
5: UL4 detection only active during speed agree, operation continues after
detection
6: UL4 detection always active during run, operation continues after detection
7: UL4 detection only active during speed agree, output shuts down on an oL4
fault
8: UL4 detection always active during run, output shuts down on an oL4 fault
Sets the overtorque and undertorque detection level.
Sets the time an overtorque or undertorque condition must exist to trigger
torque detection 2.
Sets the motor underload protection (UL6) based on motor load.
0: Base frequency enable
1: Max frequency enable
Sets the UL6 detection level at minimum frequency by percentage of drive
rated current.
0: Resistor overheat protection disabled
1: Resistor overheat protection enabled
An overheat alarm occurs when heatsink temperature exceeds the L8-02 level. Default:
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.
Selects the detection of input current phase loss, power supply voltage
imbalance, or main circuit electrolytic capacitor deterioration.
0: Disabled
1: Enabled
0: Disabled
1: Enabled (triggered by a single phase loss)
2: Enabled (triggered when two phases are lost)
0: Disabled
1: Enabled
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.
Sets a delay time to shut off the cooling fan after the Run command is removed
when L8-10 = 0.
Enter the ambient temperature. This value adjusts the oL2 detection level.
0: No oL2 level reduction below 6 Hz.
1: oL2 level is reduced linearly below 6 Hz. It is halved at 0 Hz.
0: Disabled
1: Enabled
