3.7.2 Detailed description of interfaces

This section provides the details of the I/O signal interfaces (refer to the I/O division in the table) given in
Section 3.5. Refer to this section and make connection with the external equipment.
(1) Digital input interface DI-1
Give a signal with a relay or open collector transistor. Refer to Section 3.7.3 for the source input.

(2) Digital output interface DO-1
A lamp, relay or photocoupler can be driven. Install a diode (D) for an inductive load, or install an inrush
current suppressing resistor (R) for a lamp load. (Permissible current: 40mA or less, inrush current: 100mA
or less) A maximum of 2.6V voltage drop occurs in the servo amplifier.
Refer to Section 3.7.3 for the source output.
