•You cannot set output frequencies within a jump frequency setting range, where the frequency
jump function avoids steady operation.
•The output frequency fluctuates continuously according to the acceleration/deceleration time
during both actions.
You can set up to three points for the jump frequency.

Acceleration Stop Function

•When the moment of inertia of a machine load is large, this function delays acceleration until the
motor starting slip is reduced.
Use this function, if an overcurrent trip occurs during startup.
•Does not depend on acceleration pattern selection A097, and works with all acceleration patterns.
