(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
SD
PG (NG)
PP (NP)
Max. input pulse
frequency 4 Mpulses/s
(Note 2)
Servo amplifier
Am26LS31 or equivalent

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 _ _".
