1 8 L Protection Functions
Settin 8 UL at un (Fault)
Undertorque detection works as long as a Run command is active. The operation stops and triggers a UL3 fault.
Settin UL at Speed A ree (Alarm)
Motor Underload 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 triggers a UL6 alarm.
Settin 1 UL at un (Alarm)
Motor Underload detection works as long as the Run command is active. The operation continues after detection and triggers
a UL6 alarm.
Settin 11 UL at Speed A ree (Fault)
Motor Underload detection is active only when the output speed is equal to the frequency reference (i.e., no detection during
acceleration and deceleration). The operation stops and triggers a UL6 fault.
Settin 12 UL at un (Fault)
Motor Underload detection works as long as a Run command is active. The operation stops and triggers a UL6 fault.
L 2 or ue Detection Le el 1
Sets the detection levels for torque detection function 1 as a percentage of the drive rated output current.
No
L6-02
The torque detection level 1 (L6-02) can also be supplied by an analog input terminal set to H3-
Note:
and the setting in L6-02 is disregarded.
L or ue Detection ime 1
Determines the time required to trigger an alarm or fault after exceeding the level in L6-02.
No
L6-03
L 1 Motor Underload Protection Selection
Sets Motor Underload Protection (UL6) based on motor load and determines whether the level of L6-02 refers to fbase or
fmax.
Selects the operation of underload detection UL6. Underload is detected when the output current falls below the underload
detection level defined by L6-14 and L2-02.
