U01 Maximumcompensationfrequencyduringbrakingtorquelimit

‹This function becomes effective, when the torque limit (brake) is used. The inverter controls to increase the output frequency so that torque calculations do not exceed the torque limit (brake) setting ( F41 or E17). (When F41 or E17 is set to 999, it becomes invalid.)

This function sets the increment of upper limit for output frequency.

When the regeneration avoidance is selected, the resurrection ability can be improved by raising the increment of upper limit. However, the output frequency of the inverter is limited at the frequency limit(high): F15.

U02 1st S-shape level at acceleration (start)

U03 2nd S-shape level at acceleration (stop)

U04 1st S-shape level at deceleration (start)

U05 2nd S-shape level at deceleration (stop)

‹When "2" is set in the function code: H07, both curvilinear acceleration and deceleration ranges of S-shape can be set up arbitrarily.

The range is the ratio for maximum output frequency 1 (F03) or 2 (A01) .

Acceleration time “tacc” and deceleration time “tdec” of upper figure become longer than the linear acceleration time and deceleration time. When the set acceleration time(F07，E10，E12，E14) is assumed to be “Ta” and deceleration time(F08，E11，E13，E15) is assumed to be “Td”, “tacc” and “tdec” can be calculated by the following expressions.

Setting range : 0 to 65535

‹The electrical discharge time which is measured in the factory shipment is set to function code U08 as a initial value. This value is different in each inverter.

‹The electrical discharge time of the capacitor is measured automatically, when the power supply is turned off. And, the result is stored in function code U09.

When the power supply is turned off under the conditions as follows, decrement rate (%) to the factory shipment can be measured.

Conditions: which has been described to "*Estimation

of life expectancy based on maintenance information" of the instruction manual "8-2 periodical inspection".

The result of UU 0908 ⋅ 100 is displayed in CAP=xxx.x% of maintenance information. 85% becomes a standard at the part replacement time.
