VB5N series inverter

4-2-2. Parameters of frequency setting (Group P1)
Time constant of analog filter
The inverters filter time for sample value when set the frequency by analog channel. If the wiring is too long or noise is too
serious, increase this parameter to improve the frequency stability. The longer the filter time, the stronger the noise immun-
ity ability. However, the reponse will be slower.
Frequency of VI min setting
Range: 0.00~upper limit of frequency
Frequency of VI max setting
Range: 0.00~upper limit of frequency
Frequency of CI min setting
Range: 0.00~upper limit of frequency
Frequency of CI max setting
Range: 0.00~upper limit of frequency
Max input pulse frequency of PULSE
Frequency of PULSE min setting
Range: 0.00~upper limit of frequency
Frequency of PULSE max setting
Range: 0.00~upper limit of frequency
When VI, CI and PULSE are selected as open loop frequency setting channel, the relationship between setting and the
present frequency is shown below:
