Energy Saving Mode - This function allows the inverter to deliver the mini-
mum power necessary to maintain speed at any given frequency. This works
best when driving variable torque characteristic loads such as fans and
pumps. Parameter

while a setting of 100 will yield a fast response with lower accuracy.

and ). If Overload Restriction is not enabled, then the current limit used is
150% of the inverter's rated output current.
The deceleration time is controlled so that the output current is maintained
below 150% of the inverter's rated current, and the DC bus voltage is main-
tained below the OV Trip level (400 V or 800 V).
Note If the load exceeds the rating of the inverter, the acceleration time may be
increased.
Note If using a motor with a capacity that is one size smaller than the inverter rat-
ing, enable the Overload Restriction function (

Note Be aware that the acceleration and deceleration times will vary, depending on
the actual load conditions during each individual operation of the inverter.
