12.9 L: Protection Functions
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 oL4 [Overtorque Detection 2] and operation
continues.
2 : oL @ RUN - Alarm only
When the Run command is enabled, the drive constantly detects overtorque. The drive outputs an oL4 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 oL4 [Overtorque Detection 2] and operation stops.
4 : oL @ RUN - Fault
When the Run command is enabled, the drive constantly detects overtorque. The drive outputs an oL4 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 UL4 [Undertorque Detection 2] and operation
continues.
6 : UL @ RUN - Alarm only
When the Run command is enabled, the drive constantly detects undertorque. The drive outputs a UL4 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 UL4 and operation stops.
8 : UL @ RUN - Fault
When the Run command is enabled, the drive constantly detects undertorque. The drive outputs a UL4 and
operation stops

V/f OLV OLV/PM OLV/PM AOLV/PM EZOLV
Sets the detection level for Overtorque/Undertorque Detection 2. In V/f control, drive rated output
current = 100% value. In vector control, motor rated torque = 100% value.
V/f OLV OLV/PM AOLV/PM EZOLV OLV/PM
Sets the detection time for Overtorque/Undertorque Detection 2.
V/f OLV OLV/PM AOLV/PM EZOLV OLV/PM
Sets the time constant for a primary filter to the torque reference or to the output current used to
detect overtorque/undertorque.
V/f OLV OLV/PM AOLV/PM EZOLV OLV/PM
Sets the speed where the drive detects mechanical deterioration and how the drive operates
(operation status) after detection.
