4-2 Function Mode Frequency Jump Function This function helps avoid resonant points of loaded machines. 4 •The output frequency cannot be set within the frequency range set in the frequency jump function. •The output frequency fluctuates continuously according to the acceleration/deceleration time during both actions. The jump frequency can be set at up to three points. Functions Output frequency A067 A068 A068 A065 A066 A066 A063 A064 A064 Frequency reference PID Function This function enables process control of such elements as flow rate, air volume, and pressure. 4-18 Parameter No.
