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 si gnals and DO-1
output signals are of source type. Perform wir ing according to the following interfaces.
(1) Digital input interface DI-1
EM1,
etc.
Servo amplifier
Switch
Approx. 5mA
DICOM
VCES 1.0V
ICEO 100 A
24VDC 10%
150mA
Approx. 5.6k
(2) Digital output interface DO-1
A maximum of 2.6V voltage drop occurs in the s ervo 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.
