4-2 Function Mode FV, FI Sampling Set the built-in filter applied to frequency setting signals via external voltage/current input. •Helps remove noise in the frequency setting circuit. •Set a larger data value if stable operation cannot be secured because of noise. Note that the larger the data value is, the slower the response time. •In case of setting "17", it indicates the setting of 16 moving average calculation disregarding the voltage fluctuation equivalent to 0.1 Hz. Though the frequency becomes less likely to fluctuate, the resolution for analog input decreases. This setting is not suitable for equipment that requires rapid response.
4 Functions Multi-step Speed Operation Function Set different RUN speeds by using codes and switch the set speed via the terminal. For details on the operation and settings, refer to "Multi-step Speed Operation Function" (page 4- 47). * To switch to the 2nd multi-step speed reference 0, allocate 08 (SET) to the multi-function input terminal and then turn it on. 4-11 Parameter No. Function name Data Default setting Unit A016 FV, FI sampling 1. to 17. 8.
