V/f CL-V/f OLV CLV AOLV
Sets the detection time for Overtorque/Undertorque Detection 1.
V/f CL-V/f OLV CLV AOLV
Sets the speed range that detects overtorque and undertorque and the operation of drives (operation
status) after detection.
0 : Disabled
1 : oL @ Speed Agree - Alarm only
2 : oL @ RUN - Alarm only
3 : oL @ Speed Agree - Fault

V/f CL-V/f OLV CLV AOLV
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 CL-V/f OLV CLV AOLV
Sets the detection time for Overtorque/Undertorque Detection 2.
V/f CL-V/f OLV CLV AOLV
Sets the time constant for a primary filter to the torque reference or to the output current used to
detect overtorque/undertorque.
V/f CL-V/f OLV CLV AOLV
Sets the speed where the drive detects mechanical deterioration and how the drive operates (operation
status) after detection.
0 : Disabled
1 : oL5 @ Speed > L6-09 - Alarm
2 : oL5 @ |Speed| > L6-09 - Alarm
3 : oL5 @ Speed > L6-09 - Fault
4 : oL5 @ |Speed| > L6-09 - Fault
5 : UL5 @ Speed < L6-09 - Alarm
6 : UL5 @ |Speed| < L6-09 - Alarm
7 : UL5 @ Speed < L6-09 - Fault
8 : UL5 @ |Speed| < L6-09 - Fault
V/f CL-V/f OLV CLV AOLV
Sets the speed level where the drive will operate the mechanical deterioration detection function, as a
percentage of the Maximum Output Frequency.
Note:
Parameter A1-02 [Control Method Selection] selects which parameter is the maximum output
frequency.
• A1-02 ≠ 8 [EZOLV]: E1-04 [Maximum Output Frequency]
• A1-02 = 8: E9-02 [Maximum Speed]
V/f CL-V/f OLV CLV AOLV
Sets the time for mechanical deterioration detection.
V/f CL-V/f OLV CLV AOLV
Sets the time that the drive will start mechanical deterioration detection triggered by the cumulative
operation time of the drive.
V/f CL-V/f OLV CLV AOLV
Sets the torque limit value for forward motoring as a percentage, where motor rated torque is the
100% value.
V/f CL-V/f OLV CLV AOLV
Sets the torque limit value for reversed motoring as a percentage, where motor rated torque is the
100% value.
V/f CL-V/f OLV CLV AOLV
Sets the torque limit value for forward regenerative conditions as a percentage of the motor rated
torque.
