Frequency reference by pulse train input

P ulse input trigger at slow speed – The pulse train input frequency detected is 0% less than the Pulse input

lower cut setting. If the pulse is not detected, the inverter
to low speed. Pulse input lower cut setting can be set the pulse input trigger and the reaction to stop can be
quick.
Default setting "1.00%" is 0.5Hz (as the maximum frequency is 50.0Hz) which is equivalent to default setting of
the start frequency (b082).

If you set the "Pulse input lower cut setting" to high value, the motor may start to run slowly to cut the
input frequency.
