Learning Basic Features
Frequency Jump
Use frequency jump to avoid mechanical resonance frequencies. Jump through up to three
frequency bands during acceleration and deceleration. Reference frequencies cannot be set within
the pre-set jump frequency band.
When the reference frequency is increased it will be maintained at the lower limit of a jump
frequency band. As the reference frequency continues to increase and exceeds the range of a jump
frequency band, it will jump to the upper limit of the jump frequency band. Decreasing reference
frequencies operate in the same manner, jumping from upper limit to lower limit. Jump frequencies
apply to all reference frequency sources (voltage, current, RS-485 communication, keypad setting).
