Setting 4: oL3/oL4 at Run - Fault
Overtorque detection works whenever a Run command is active. The operation is stopped and an oL3/oL4 fault is triggered.
Setting 5: UL3/UL4 at Speed Agree - Alarm
Undertorque detection is active only when the output speed is equal to the frequency reference, i.e., no detection during
acceleration and deceleration. The operation continues after detection and a UL3/UL4 alarm is triggered.
Setting 6: oL5/UL5 at Run - Alarm
Undertorque detection works whenever a Run command is active. The operation continues after detection and an oL5/UL5
alarm is triggered.
Setting 7: UL5 at Speed Agree - Fault
Undertorque detection is active only when the output speed is equal to the frequency reference, i.e., no detection during
acceleration and deceleration. The operation is stopped and a UL5 fault is triggered.
Setting 8: oL3/oL4 at Run - Fault
Undertorque detection works whenever a Run command is active. The operation is stopped and an oL3/oL4 fault is triggered.
Setting 9: UL6 Alarm at Speed Agree
Setting 10: UL6 Alarm during Run
Setting 11: UL6 Fault at Speed Agree
Setting 12: UL6 Fault during Run
L6-02/L6-05: Torque Detection Level 1/2
n
These parameters the detection levels for the torque detection functions 1 and 2.
No.
L6-02
L6-05
Note: 1. The torque detection level 1 (L6-02) can also be supplied by an analog input set to H3-02/10 = 7. In this case the analog value has priority
and the setting L6-02 is disregarded. Torque detection level 2 (L6-05) cannot be set by an analog input.
2. The detection levels for overtorque and undertorque are set as a percentage of the drive rated current when using V/f Control or Open
Loop Vector Control. When using Closed Loop Vector Control, the drive sets torque detection as a percentage of the motor rated current.
L6-03/L6-06: Torque Detection Time 1/2
n
These parameters set the time that the levels set in L6-02/05 have to be exceeded before an alarm/fault is triggered.
No.
L6-03
L6-06
L6-13: Motor Underload Protection Selection
n
Sets the motor underload protection (UL6) based on motor load.
No.
L6-13
Setting 0: Base frequency enable
Setting 1: Max frequency enable
L6-14: Motor Underload Protection Level at Minimum Frequency
n
Sets the motor underload protection (UL6) based on motor load.
No.
