Command input pulse train form selection
0: Forward/reverse rotation pulse train
1: Signed pulse train
2: A-phase/B-phase pulse train (The driver imports input pulses after multiplying by
four.)

Pulse train logic selection
0: Positive logic
1: Negative logic
Choose the right parameter to match the logic of the command pulse train received
from a connected controller. Refer to POINT of section 3.6.1 for logic of MELSEC
iQ-R series/MELSEC-Q series/MELSEC-L series/MELSEC-F series.
Refer to table 5.3 for settings.

Command input pulse train filter selection
Selecting proper filter enables to enhance noise tolerance.
0: Command input pulse train is 4 Mpulses/s or less.
1: Command input pulse train is 1 Mpulse/s or less.
2: Command input pulse train is 500 kpulses/s or less.
3: Command input pulse train is 200 kpulses/s or less
1 Mpulse/s or lower commands are supported by "1". When inputting commands
over 1 Mpulse/s and 4 Mpulses/s or lower, set "0".
Incorrect setting may cause the following malfunctions.
Setting a value higher than actual command will lower noise tolerance.
Setting a value lower than actual command will cause a position mismatch.
