Pr. 31 to 36 "speed command jumps 1A to 3B"
Pr. Setting Range Unit
31 to 36 0 to 7200, 9999 r/min
You can set three speed areas where continuous operation will be disabled. You
can avoid continuous operation at the speed at which resonance will occur due to
the natural frequency of a mechanical system. When the speed command within
the setting range is input, continuous operation is performed at the preset speed
of value A.
Setting "9999" in the parameter makes this function invalid.
