HV100 Series High Performance Current Vector Inverter
68
The above function codes are functions set to make the output frequency of inverter avoid the resonance frequency
point of mechanical load. The set frequency of the inverter can be given by jumping near some frequency points according
to the following figure. Its specific meaning is that the frequency of the inverter will never run stably within the jumping
frequency range, but will pass through this range during acceleration and deceleration.

0: Run at the lower limit frequency.
When the set frequency is lower than the set value of the lower limit frequency (00.14), the inverter operates at the
lower limit frequency.
1: Zero frequency operation after delay time
When the set frequency is lower than the set value of the lower limit frequency (00.14), the inverter runs at zero
frequency after a delay time (01.32).
2: Shutdown after a delay time
When the set frequency is lower than the set value of the lower limit frequency (00.14), the inverter stops after a delay
time (01.32).

The waiting time for the inverter to transition from forward operation to reverse operation, or from reverse operation to
forward operation, as shown in the t1 figure below. The waiting frequency of switching transition is also related to the
setting of 01.35.
