B. Energy Saving Tuning
In the energy saving control mode, the optimum voltage is calculated according to load
power, and this voltage is supplied to the load. However, since the set parameter may
change due to temperature variations or using other manufacturers’ motors, the optimum
voltage may not necessarily be supplied. Automatic tuning controls the voltage so that
highly efficient operation is maintained.
n100 : Time of Average kW Factory setting: 1
(EngSavTime/Avg/kW)
Range: 1 to 200 (x 25 ms)
Sets adjustment time of kW saving. By increasing this value, the response time to a
change in load is increased, which may prevent the system from oscillating. However,
too long of a response time may starve the motor of voltage.
