6.9.2 Stepwise output pulse
The output pulse frequency (f) of FX3U-1PG is stepwise as follows.
Where, n: Integer in range of 120 to 24,000,000
For example,
n = 120 → f = 200,000 Hz
n = 121 → f = 198,347 Hz
Any pulse whose frequency is between the two values above cannot be generated.
Point
In the operation speed current value (BFM#61, #60), the actual operation speed is stored. Because the actual
output pulse is stepwise, it is possible that the current operation speed value is different from the user set
operation speed I (BFM#20, #19), the operation speed II (BFM#24, #23), and the operation speed change
value (BFM#56, #55).
