Note 1. The
above K2 values are for standard motors and dedicated motors for inverters. The Inverter
in
energy-saving mode cannot save unnecessary power supply to
high-speed motors (e.g.,
spindle
motors) or any other motor that has an ef
ficiency curve with more than one peak (e.g.,
any double squirrel-cage motor).
Note 2. The
Inverter performs energy-saving control at 15 to 120 Hz. The Inverter does not perform
energy-saving control at a frequency exceeding 120 Hz.
n100 Search Control Voltage Limit
Setting range 0 to 100 Unit % (Rated input
voltage ratio of
motor)
Default setting 0
Set Values
S Set
the range of the variable voltage of the Inverter in search operation mode with 1% units based
on the rated input voltage of the motor set with n011 as 100%.
S The value of n100 is usually set to a range from 0 to 20%. Usually n100 is set to 10%.
S The search operation will not be available if n100 is set to 0.
n097 Energy-saving Voltage Lower Limit for 60 Hz
Setting range 0 to 120 Unit % (Rated input
voltage ratio of
motor)
Default setting 50
