4-2 Function Mode Frequency Jump Function •The frequency jump function helps avoid resonant points of loaded machines. 4 •You cannot set output frequencies within a jump frequency setting range, where the frequency jump function avoids steady operation. •The output frequency fluctuates continuously according to the acceleration/deceleration time during both actions. You can set up to three points for the jump frequency. Functions Acceleration Stop Function •When the moment of inertia of a machine load is large, this function delays acceleration until the motor starting slip is reduced. Use this function, if an overcurrent trip occurs during startup.
•Does not depend on acceleration pattern selection A097, and works with all acceleration patterns. 4-30 Parameter No. Function name Data Default setting Unit A063 A065 A067 Jump frequency 1 Jump frequency 2 Jump frequency 3 0.0 to 400.0 0.0 Hz A064 A066 A068 Jump frequency width 1 Jump frequency width 2 Jump frequency width 3 0.0 to 10.0 0.5 Related functions C001 to C008 Output frequency A067 A065 A063 A068 A068 A066 A066 A064 A064 Frequency reference Parameter No. Function name Data Default setting Unit A069 Acceleration stop frequency 0.0 to 400.0 0.00 Hz A070 Acceleration stop time 0.0 to 60.0 0.0 s Output frequency A069 A070 Frequency reference
