Description
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.

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.

V/f CL-V/f OLV CLV AOLV
mechanical deterioration detection function, with E1-04 [Maximum
Output Frequency] is the 100% value.
V/f CL-V/f OLV CLV AOLV
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.
Description
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.
