3. SIGNALS AND WIRING
(3) Pulse train input interface DI-2
Give a pulse train signal in the differential line driver type or open-collector type.
(a) Differential line driver type
1) Interface
2) Input pulse condition
(b) Open-collector type
1) Interface
10 m or less

Am26LS31 or equivalent
V : 2.5 V
OH
V V : 0.5 V
OL
Note 1. 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.
2. When the input pulse frequency is 4 Mpulses/s, set [Pr. PA13] to "_ 0 _ _".
