(2) Digital output interface DO-1
This is a circuit in which the emitter side of the output transistor is the output terminal. When the output
transistor is turned on, the current flows from the output terminal to a load.
A maximum of 2.6 V voltage drop occurs in the servo amplifier.
(Note) 24 V DC ± 10%
500 mA

If polarity of diode is
reversed, servo amplifier
will malfunction.
Note. If the voltage drop (maximum of 2.6 V) interferes with the relay operation, apply high
voltage (maximum of 26.4 V) from external source.
(3) Pulse train input interface DI-2
Give a pulse train signal in the open-collector type.

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.
