3.6.2 Detailed description of the interfaces
This section gives the details of the I/O signal interfaces (refer to I/O Division in the table) indicated in
Sections 3.3.2.
Refer to this section and connect the interfaces with the external equipment.
(1) Digital input interface DI-1
Give a signal with a relay or open collector transistor.
VIN
SG
Switch
SON, etc.
External power
supply 24VDC
200mA or more
Servo amplifier
R: Approx. 4.7
(2) Digital output interface DO-1
A lamp, relay or photocoupler can be driven. Provide a diode (D) for an inductive load, or an inrush
current suppressing resister (R) for a lamp load. (Permissible current: 40mA or less, inrush current:
100mA or less)
(a) Inductive load
VIN
SG
Servo amplifier
Load
ALM, etc.
If the diode is not
connected as shown,
the servo amplifier
will be damaged.
External power
supply 24VDC
