n098 Energy-saving Voltage Lower Limit for 6 Hz
Setting range 0 to 25 Unit % (Rated input
voltage ratio of
motor)
Default setting 12
Set Values
S Set the lower output voltage limits of the Inverter in energy-saving mode.
S It is usually unnecessary to change the default-set values of n097 and n098.
S The parameters n097 and n098 set the lower output voltage limits of the Inverter to prevent the
motor from stalling.
S Set n097 and n098 to values 5% to 10% larger than the default-set values if the motor stalls.
Output voltage lower limit (%)
n099 Mean Power Time
Setting range 1 to 200 Unit x 25 ms Default setting 1
Set Values
S Set time to calculate the mean output power of the Inverter in energy-saving mode.
S It is usually not necessary to change the default-set value of n099.
S The
Inverter calculates its mean
output power during the time set with n099 for the energy-saving
control of the motor.
S The time set with n099 is used as a search operation period, in which the output voltage of the
Inverter in search operation mode changes.
S Set
n099 to a value larger than the default-set value if the load factor of the motor changes greatly
or the friction factor of the load is large and the motor vibrates.
n101 Search Operation Control Voltage Step when 100%
Setting range 0.1 to 10.0 Unit % (Rated input
voltage ratio of
motor)
Default setting 0.5
n102 Search Operation Control Voltage Step when 5%
Setting range 0.1 to 10.0 Unit % (Rated input
voltage ratio of
motor)
Default setting 0.2
Set Values
S The
values set with n101 and n102 are used
as voltage change rates, at which the output voltage
of the Inverter in search operation mode changes.
S It is usually not necessary to change the default-set values of n101 and n102.
