107
In the energy 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 parameters, 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 parameters 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.
