Frequency reference by pulse train input
•
Pulse 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
‘
s reaction is too slow when the pulse can be detected
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).
