ŬIf the upper limit frequency (WN) is within jump frequency range,
it is limited to the lowest frequency in the jump frequency range.
ŬIf the lower limit frequency (NN) is within jump frequency range,
it is limited to the highest frequency in the jump frequency range.
ŬDo 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.
ŬDo not overlap two or more jump frequency ranges, or
it cannot be operated within normal range.
ŬDuring acceleration or deceleration,
the jumping function is disabled for the operation frequency.

• Function
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
