POINT
This parameter is made valid when power is switched off, then on after setting.
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.
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.
