This is the no load current of the motor and can be measured when no load
is connected to the motor.
Enter the 50% of the rated current value when it is difficult to measure H34
- [No Load Motor Current].
H34 is only displayed when 'Slip Compen' is selected in H40 [Control
Method].
(This value is set according to the motor capacity set in H30)
Slip compensation is used to maintain the motor speed constantly. To keep
the motor speed constant, the output frequency varies within the limit of slip
frequency set in H32 according to the load current. For example, when the
motor speed decreases below the reference speed (frequency) due to a heavy
load, the drive increases the output frequency higher than the reference
frequency to increase the motor speed. The drive increases or decreases the
output by delta frequency shown below.
Delta Output current - No load current
=
Freq.
Rated current - No load current
Output frequency = Reference freq. + Delta freq.
50-100% (Default: 87%)
This parameter is used for caculating the output wattage when H72 is set to
'Watt'. (This value is set according to the motor capacity set in H30).
