Functions
Frequency Limit
This function limits the Inverter output frequency.
* To switch to the 2nd control, allocate 08 (SET) to the multi-function input terminal and then turn it on.
•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 fluctuates continuously according to the acceleration/deceleration time
during both actions. The jump frequency can be set at up to three points.
