range
Note 1. The default setting varies with the capacity of the Inverter model.
Note 2. The constant automatically changes according to the motor code in n158. For the fine-tuning
of this parameter, set the motor code in advance.
Set Values
• When the output frequency is constant for a certain period while the Inverter is in effective energy-sav-
ing control, the Inverter is set to the primary level of energy-saving control by this parameter.
• Motor constants vary with the motor manufacturer. Therefore, the fine-tuning of the parameter is
required to find the ideal value. Fine-tune the parameter while the Inverter is operating at constant
frequency so that the output power will be minimum.
