Set Values
·
When the output frequency is constant for a certain period while the Inverter is in effec-
tive energy-saving control, the Inverter will be set to the primary level of energy-saving
control by n140 (energy-saving constant K2). Then the Inverter will be set to the sec-
ondary level (i.e., probe operation) for more efficient, energy-saving control. Set the
control voltage range of the Inverter in probe operation in parameter n144.
·
Set the upper limit of probe operation voltage in percentage based on the rated motor
voltage as 100%. Normally set the value to approximately 10%.
·
No probe operation will be available if the value is set to 0.

·
Set the range of probe operation voltage in percentage based on the rated motor volt-
age as 100%.
·
Normally, the default setting does not need to be changed.
·
If the fluctuation of speed in probe operation is large, decrease the set value. If the
response of the Inverter in probe operation is slow, increase the set value.

Set this parameter to the detection width of power that sets the Inverter to probe opera-
tion. When the fluctuation of power is within the detection width, the Inverter will be in
probe operation.
