3.7.3 Source I/O interfaces
In this servo amplifier, source type I/O interfaces can be used. In this case, all DI-1 input signals and DO-1
output signals are of source type. Perform wiring according to the following interfaces.
(1) Digital input interface DI-1
EM1,
etc.

A maximum of 2.6V voltage drop occurs in the servo amplifier.
If polarity of diode is
reversed, servo
amplifier will fail.

(Note)
Note. If the voltage drop (maximum of 2.6V) interferes with the relay operation, apply high voltage (up to
26.4V) from external source.
