(Note)
Note. Pulse train input interface is comprised of a photo coupler.
Therefore, it may be any malfunctions since the current is reduced when connect a
resistance to a pulse train signal line.
The explanation assumes that the input waveform has been set to the negative logic and forward
and reverse rotation pulse trains (parameter No.21 has been set to 0010). The waveforms in the
table refer to (1) (a) in this section are voltage waveforms of PP and NP based on SG. Their
relationships with transistor ON/OFF are as follows.
