4-2 Function Mode 4 Frequency Limit Functions This function limits the Inverter output frequency. * To switch to the 2nd control, allocate 08 (SET) to the multi-function input 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. Set frequency (Hz) Maximum frequency A004/A204 A061 A062 0V 4mA 10V 20mA Frequency reference If the lower limit is set, the set value is prioritized even if 0 V (4 mA) is input for frequency reference.
