Functions
•You can set both upper/lower limits to the set frequency. This function does not accept any
frequency reference beyond the set limits.
•Set the upper limit first.
Make sure the upper limit (A061/A261) is higher than the lower limit (A062/A262).
•Neither limit would work if set to 0 Hz.
If the lower limit is set, the set value is prioritized even if 0 V (4 mA) is input for frequency reference.
Frequency Jump Function
This function helps avoid resonant points of loaded machines.
•The output frequency cannot be set within the frequency range set in the frequency jump function.
•The output frequency only pass through the jump frequency during acceleration and deceleration
process, but if the frequency reference is set inside this area the output will move automatically out
of this jump area setting a higher or lower frequency depending if inverter is accelerating or
decelerating.
