Instruction manual

103
In the energy-saving control mode, the max. applicable voltage is
calculated using the output power. However, a temperature change
or the use of another manufacturer’s motor will change the fixed
constants, and the max. applicable voltage may not be emitted. In
the search operation, change the voltage slightly so that the max.
applicable voltage can be obtained.
• Search operation Voltage Limit (n144)
Limits the range where the voltage can be controlled. The constants
are set in % for 200V/400V inverters. The search operation is not
performed when set to 0.

• Search Operation Voltage Step (n145, n146)
Sets the voltage fluctuations for one cycle of the search operation.
Increase the value and the fluctuation of the rotation speed will also
increase. Sets the range. The value calculated by linear interpolation
is set for voltage other than above.
