Name
The set frequency data entered from the digital signal input terminals (X0 to X15) is
always imported independently of whether the DY signal is on or off.
The set frequency data entered from the digital signal input terminals (X0 to X15) is
imported only when the DY signal is on.
The set frequency data is not imported when the DY signal is off.
Therefore, even if the input status of the X0-X15 signal changes, the set frequency
data before off of the DY signal is valid.
The set frequency data entered from the digital signal input terminals (X0 to X15) is
always imported independently of whether the DY signal is on or off.
The time lag when digital signals change can be compensated with a filter.
