note 1
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 effec-
tive energy-saving control, the Inverter is set to the primary level of energy-saving con-
trol 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.
