Setting 2: oL3 at Run (Alarm)
Overtorque detection works as long as the Run command is active. The operation continues after detecting overtorque and
triggering an oL3 alarm.
Setting 3: oL3 at Speed Agree (Fault)
Overtorque 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 an oL3 fault.
Setting 4: oL3 at Run (Fault)
Overtorque detection works as long as a Run command is active. The operation stops and triggers an oL3 fault.
Setting 5: UL3 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 detecting overtorque and triggering a UL3 alarm.
Setting 6: UL3 at Run (Alarm)
Undertorque detection works as long as the Run command is active. The operation continues after detecting overtorque and
triggering a UL3 alarm.
Setting 7: UL3 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 stops and triggers a UL3 fault.
Setting 8: UL3 at Run (Fault)
Undertorque detection works as long as a Run command is active. The operation stops and triggers a UL3 fault.
Setting 9: UL6 at Speed Agree (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.
Setting 10: UL6 at Run (Alarm)
Motor Underload detection works as long as the Run command is active. The operation continues after detection and triggers
a UL6 alarm.
Setting 11: UL6 at Speed Agree (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.
Setting 12: UL6 at Run (Fault)
Motor Underload detection works as long as a Run command is active. The operation stops and triggers a UL6 fault.
n L6-02: Torque Detection Level 1
Sets the detection levels for torque detection function 1 as a percentage of the drive rated output current.
No. Name Setting Range Default
L6-02 Torque Detection Level 1 0 to 300% 15%
Note: The torque detection level 1 (L6-02) can also be supplied by an analog input terminal set to H3- = 7. Here, the analog value has priority
and the setting in L6-02 is disregarded.
n L6-03: Torque Detection Time 1
Determines the time required to trigger an alarm or fault after exceeding the level in L6-02.
No. Name Setting Range Default
L6-03 Torque Detection Time 1 0.0 to 10.0 s 10.0 s
n o2-03: User Parameter Default Value
After completely setting up drive parameters, save the values as user-set defaults with parameter o2-03. After saving the values,
parameter A1-03 (Initialize Parameters) will offer the choice of "1110: User Initialize". Selecting 1110 resets all parameters
to the user-set default values. Refer to A1-03: Initialize Parameters on page 150 for details on drive initialization.
No. Name Setting Range Default
o2-03 User Parameter Default Value 0 to 2 0
