3. SIGNALS AND WIRING
The following section explains about the case where the negative logic and the forward/reverse
rotation pulse trains are set to "_ _ 1 0" in [Pr. PA13].
Forward rotation pulse train
(transistor)
Reverse rotation pulse train
(transistor)
2) Differential line driver type
Connect as follows.
The following section explains about the case where the negative logic and the forward/reverse
rotation pulse trains are set to "_ _ 1 0" in [Pr. PA13]. The waveforms of PP, PG, NP, and NG are
based on LG.

(Note)
Note. Pulse train input interface is comprised of a photocoupler.
If a resistor is connected to the pulse train signal line, it may malfunction due to
reduction in current.
