2) During traverse run, the center frequency could be controlled by the multifunction input terminals.
However, the X up deviation and Y low D deviation can not be input at the same time. If they are
input at the same time, the inverter will maintain the original center frequency. The motion is as
the graph below:

5-00 ~ 5-06 = 26
5-00 ~ 5-06 = 27
3) The stall prevention is idle in the acceleration and deceleration time of traverse run. Whereas, it is
valid during first acceleration to center frequency process when the Function of traverse run is
OFF or the inverter is in deceleration time after the STOP command is received.
4) The frequency range of traverse run is restricted by the inverter upper and lower frequency limit.
That is: if the (center frequency + Amplitude) is larger than Upper Limit, it will operate at upper
frequency limit. And if (center frequency - Amplitude) is less than Lower Limit, vice versa.
5) During traverse run, all the preset values can't be modified such as (center frequency, amplitude,
amplitude drop, acceleration time. deceleration time, traverse run upper deviation and lower
deviation). The modified acceleration and deceleration time is priority to the original one, but not
traverse run acceleration and deceleration time. The motion is as graph below:
6) The stall prevention protection is unavailable during traverse run acceleration and deceleration
time. Thusly, it is must take into consideration to comply the actual system capacity with the
proper inverter capacity when designing equipment.
7) Center frequency = 3-23*max. frequency(3-00)
Amplitude = 3-24*center frequency
Acceleration / Deceleration time = amplitude acceleration / deceleration time
Amplitude Drop = 3-25*amplitude
Deviated traverse (X upper deviation) = 3-28*traverse run center
Deviated traverse ( Ｙ lower deviation) = 3-29* traverse run center
If change the max. frequency of 3-00, reset 3-23~3-29 value is necessary.
