High-speed F/V converter
FV-1500

The FV-1500 high-speed F/V converter is a highly responsive frequency (F)/voltage (V) converter that converts frequency signals proportional to rotational speed and movement speed into voltage signals.

It supports motors used in hybrid and electric vehicles, as well as the acceleration of manufacturing lines in production factories, and can measure transient phenomena such as startup characteristics, minute rotational fluctuations during steady rotation, and flow rate changes with high response.

Features

  • Wideband 0.2 Hz to 320 kHz (1 Hz to 120 kHz for conventional products)

  • High-speed response 1 cycle + 3.5 μs (1 cycle + 7.6 μs for conventional products)

  • A rapid deceleration tracking function that maintains output close to ideal even when the frequency suddenly decreases.

  • Center frequency tracking function that only amplifies transient fluctuation components (optional)

  • 2-phase signal input compatibility for determining rotation direction with forward and reverse output.

  • Comparator output (optional) for alarm control.

main uses

  • motor startup characteristics

  • Measurement of rotational performance of various rotating machinery.

  • Measurement of rotational fluctuations in engines and motors.

  • Rotational performance test due to overload

What is the rapid deceleration following function?

Emergency Deceleration Follow Function Operation Image
Emergency Deceleration Follow Function Operation Image

When the input signal rapidly decelerates due to a rotating body, and no input is received beyond the previous pulse interval, this function reduces and stops the rotational output (speed analog).

When Follow Function is ON:
If no signal input is received after waiting for 1.5 to 16 times the previous signal pulse interval, the analog output will become 0.
When Follow Function is OFF:
After the input signal becomes 0 (OFF), the analog output will become 0 after being held at the minimum measurement frequency (0.2 Hz).
