Frequently Asked Questions about FV Converters

Question number FAQ-0836

The relationship between the frequency range and voltage output of the FV-1100 F/V converter is

The standard specification of the FV-1100 is max 10kHz.

When the operating frequency is below 50% of the frequency range, the output voltage decreases while the ripple ^* increases, resulting in poor accuracy within the usable range.
It is recommended to modify the system so that the frequently used frequency range approaches the full-scale frequency.

(for example)

In the 10kHz range, the accuracy is ±0.2%, which means
→ 20mV/10V full scale/10kHz full scale

If the operating range is below 1kHz,
since 1kHz = 1V, the accuracy for 1kHz is,
→ 20mV ÷ 1V = 2% / 1V / accuracy at 1kHz.

When modifying 1kHz to full scale
→ it becomes 0.2% / 10V full scale / 1kHz full scale.

The usage range of the FV converter should be considered approximately between 10% and 100% of the full-scale frequency range.
