Jump Frequency - Jumping Resonant Frequencies - Toshiba TOSVERT VF-PS1 Instruction Manual

If two signals are input simultaneously
• If a clear single and an up or down signal are input simultaneously, priority will be given to the clear signal.
• If up and down signals are input simultaneously, the frequency will be increased or reduced by the difference between
the settings of
value obtained by subtracting the setting of
Setting of the initial Up/Down frequency
To adjust the frequency start at a specified frequency other than 0.0 Hz (default initial frequency) after turning on the
inverter, specify the desired frequency using
Change of the initial Up/Down frequency
To make the inverter automatically save the frequency immediately before it is turned off and start operation at that
frequency next time power is turned on, set
setting of when power is turned off).
Keep in mind that the setting of

• Function
Resonance due to the natural frequency of the mechanical system can be avoided by jumping the resonant
frequency during operation. During jumping, hysteresis characteristics with respect to the jump frequency
are given to the motor.
