If the upper limit frequency (WN) is within jump frequency range,
it is limited to the lowest frequency in the jump frequency range.
+
If the lower limit frequency (NN) is within jump frequency range,
it is limited to the highest frequency in the jump frequency range.
+
Do not overlap upper limit frequency (WN) and lower limit frequency (NN)
within jump frequency range.
If they are overlapped, it is operated lowest jump frequency.

Do not overlap two or more jump frequency ranges, or
it cannot be operated within normal range.

Forced operation control is used when operating the motor at the specified frequency in case of an
emergency. If forced operation control
is assigned to the terminal board selection parameter and a forced
operation control
signal is given, the motor will be operated at the frequency specified with H (preset
speed operation frequency 15). (When the input terminal board selection parameter is set to or .)
