3.4 Detailed description of the signals
3.4.1 Position control mode
(1) Pulse train input
(a) Input pulse waveform selection
Command pulses may be input in any of three different forms, for which positive or negative logic
can be chosen. Set the command pulse train form in parameter No. 21.
Arrow or in the t able indicates the timing of importing a pul se train.
A- and B-phase pulse trains are imported after they have been multiplied by 4.
