Set Values
•This
function will decrease the output frequency
if the output current exceeds the set
current
value by a minimum of approximately 100 ms so that the Inverter will continue
operating
without
stalling. The Inverter will increase the output frequency to return to
the set frequency reference level when the output current is less than the set value.
•The
Inverter accelerates or decelerates the output frequency according
to the preset
acceleration or deceleration time. (Acceleration
time 1: n16, n17 or acceleration time
2: n18, n19)
•Set the parameter as percentage based on the rated Inverter current as 100%.
•The default setting does not need any changes in normal operation.
•Decrease
the set value if the capacity of the motor is smaller than
that of the Inverter or
the motor stalls with the default value.
The
set value is normally 2 or 3 times higher than the rated current of the motor
. Set this
current in percentage based on the rated Inverter current as 100%.
