4-2 Function Mode Frequency Limit This function limits the Inverter output frequency. 4 Functions * 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. Max. frequency A004/A204 Set frequency (Hz) A061 A062 Frequency reference 0V 4mA 10V 20mA 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. 4-19 Parameter No. Function name Data Default setting Unit A061 Frequency upper limit 0.0/Frequency lower limit [A062] to Max. frequency [A004] 0.0 Hz * A261 2nd frequency upper limit 0.0/Frequency lower limit [A262] to Max.
