No. Name and function
PA13 Command pulse input form
Turn off the power and then on again after setting
the parameter to validate the parameter value.
Select the input form of the pulse train input signal.
Command pulses may be input in any of three
different forms, for which positive or negative logic
can be chosen.
Arrow or in the table indicates the timing
of importing a pulse train.
A- and B-phase pulse trains are imported after they
have been multiplied by 4.

_ _ _ x:
Command input pulse train form selection
0: Forward/reverse rotation pulse train
1: Signed pulse train
2: A-phase/B-phase pulse train (The servo amplifier
imports input pulses after multiplying by four.)
Refer to table 2.3 for settings.
_ _ x _:
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 Servo Amplifier Instruction
Manual of MELSEC iQ-R series/MELSEC-Q
series/MELSEC-L series/MELSEC-F series.
Refer to table 2.3 for settings.
_ x _ _:
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 (available for the software version A5 or
later)
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.

Arrows in the table indicate the timing of importing
pulse trains. A-phase and B-phase pulse trains are
imported after they have been multiplied by 4.
