reset times PA.21, it will alarm then stop. For defaults such as overcurrent or overvoltage occurred
occasionally from beginning or during running, the function can be used if you want the equipment keep
running without manual interfere.
Note: For fault E.PCU, E.rEF, E.AUt, E.FAL, E.oUt, E.ot1, E.ot2, E.Cur, E.GdF, E.LV1, E.CPy, E.dL4,
E.IoF and E.oL3, there has no auto reset function. The inverter will not check fault.
6.12 Enhanced Function Parameter (Group Pb)
Set hopping frequency range of inverter to avoid mechanical
resonance. When the setting frequency of
inverter is less than the hopping frequency, the inverter will run automatically at the upper limit or lower
limit of the hopping frequency (change to run at lower limit of the hopping frequency when acceleration,
for deceleration, change to run at upper limit of the hopping frequency), as shown in Fig. 6-34.

For some special applications that longer acceleration/deceleration time is required, the function can be
used to determine magnification of acceleration/deceleration time that has been set. For example, if the
