YASKAWA HV600 Technical Reference page 339

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.

L6-02: Torque Detection Level 1
No.
Name
(Hex.)
L6-02 Torque Detection Level 1
(04A2)
Note:
You can also use an analog input terminal to supply the torque detection level. To enable this function, set H3-xx = 7 [MFAI Function Select
= Overtorque/Undertorque DetectLvl]. If you set L6-02 and H3-x = 7, the analog input is most important and the drive disables L6-02.

L6-03 Torque Detection Time 1
(04A3)
YASKAWA SIEPYAIH6B01A HV600 AC Drive Bypass Technical Reference
Sets the detection level for Overtorque/Undertorque Detection 1. In V/f control, drive rated output
current = 100% value. In vector control, motor rated torque = 100% value.
Sets the detection time for Overtorque/Undertorque Detection 1.
