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.
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).
