Introduction 
 
PA13 Selection of command input pulse form (refer to section 4.1.11) 
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 being multiplied by 4.

POINT 
 
The noise tolerance can be enhanced by setting parameter No. PA13 to "1     " 
when the command pulse frequency is 500kpps or less or "2 
   " when 
200kpps or less.
