(33) Energy-savings tuning operation (Cn-49 to Cn-52)

• In the energy-savings mode (Sn-09 = X1XX) the optimum voltage is calculated according

to load power and the voltage is supplied to the load. However, since the motor settings

diﬀer depending on temperature variation or use of other manufacturers’ motors, the output

voltage is not always optimum. At tuning, operation is controlled so that the optimum operating

status can be obtained by ﬁne adjustment of voltage.

(a)

Tuning Operation voltage Limit (Cn-49)

Limits the range where voltage is controlled by tuning operation. Setting is

made in the units of % of rated voltage. By setting this value to 0, tuning

operation is not performed.

(b)

Tuning Operation Control Cycle (Cn-50)

Sets the control cycle of tuning operation.

(c)

Tuning Operation voltage Step (Cn-51, 52)

Sets voltage variation width of one tuning operation cycle. Setting is made in

the units of % of rated voltage. By increasing this value, rotation speed variation

becomes larger. Initial values are100% and 5%. With other voltage values, voltage

variation width obtained by linear interpolation is set.

Please refer to Appendix A for a detailed discussion of Energy-Savings Mode.

(34) Energy-saving coeﬃcient K2 (Cn-58)

• Voltage at which the motor eﬃciency will be the maximum is calculated by using this

coeﬃcient at operation in the energy-saving mode, and the resulting value is the

voltage reference. This value is initially set to the value of a TECO-Westinghoue motor.

By increasing the energy-saving coeﬃcient, output voltage becomes larger.

• Please refer to Appendix A for a detailed discussion of Energy-Savings Mode.
