(Hex.)
L6-01 Torque Detection Selection 1
(04A1)
• The drive detects oL [overtorque] if the motor current or output torque is more than the level set in L6-02 [Torque
Detection Level 1] for the time set in L6-03 [Torque Detection Time 1].
• The drive detects UL [undertorque] if the motor current or output torque is less than the level set in L6-02 for the
time set in L6-03.
• The drive detects UL6 [Underload or Belt Break Detected] if the motor current or output torque is less than the
linear curve set in L6-02 and L6-14 [Motor Underload Level @ Min Freq].
0 : Disabled
The drive will not detect overtorque or undertorque.
1 : oL @ Speed Agree - Alarm only
The drive detects overtorque when the output frequency aligns with the frequency reference. Detection does not occur
during acceleration/deceleration. The drive outputs an oL3 [Overtorque Detection 1] and operation continues.
2 : oL @ RUN - Alarm only
When the Run command is enabled, the drive constantly detects overtorque. The drive outputs an oL3 and operation
continues.
3 : oL @ Speed Agree - Fault
The drive detects overtorque when the output frequency aligns with the frequency reference. Detection does not occur
during acceleration/deceleration. The drive outputs an oL3 [Overtorque Detection 1] and operation stops.
4 : oL @ RUN - Fault
When the Run command is enabled, the drive constantly detects overtorque. The drive outputs an oL3 and operation
stops.
5 : UL @ Speed Agree - Alarm only
The drive detects undertorque when the output frequency aligns with the frequency reference. Detection does not
occur during acceleration/deceleration. The drive outputs a UL3 [Undertorque Detection 1] and operation continues.
6 : UL @ RUN - Alarm only
When the Run command is enabled, the drive constantly detects undertorque. The drive outputs a UL3 and operation
continues.
7 : UL @ Speed Agree - Fault
The drive detects undertorque when the output frequency aligns with the frequency reference. Detection does not
occur during acceleration/deceleration. The drive outputs a UL3 and operation stops.
8 : UL @ RUN - Fault
When the Run command is enabled, the drive constantly detects undertorque. The drive outputs a UL3 and operation
stops
9 : UL6 @ Speed Agree - Alarm only
The drive detects and shows a UL6 [Underload or Belt Break Detected] alarm during speed agree. The drive will
clear the alarm when the output current increases to more than the UL6 detection level plus 10% of the drive rated
current.
10 : UL6 @ RUN - Alarm only
The drive detects and shows a UL6 alarm while the drive is in the operation. The drive will clear the alarm when the
output current increases to more than the UL6 detection level plus 10% of the drive rated current.
11 : UL6 @ Speed Agree - Fault
The drive detects and shows a UL6 fault during speed agree.
12 : UL6 @ RUN - Fault
The drive detects and shows a UL6 fault while the drive is in the operation.

V/f OLV/PM EZOLV OLV/PM
Sets the speed range that detects overtorque and undertorque and the operation of drives (operation
status) after detection.
