5 Selecting PG
The maximum frequency of PG output pulse that can be detected is 300kHz.
Find output frequency, f
PG
(Hz), according to the following formula.
f
PG
(Hz) =
Motor rotation speed

If the PG power capacity is 200mA or greater, provide a separate power supply.
(If momentary power loss ride-through function is necessary, provide backup
capacitor or take other necessary measures.)
