3. SIGNALS AND WIRING
Note 1. P: Position control mode
2. For the differential line driver pulse train input. For the open collector pulse train input, make the following connection.
3. For the sink I/O interface. For the source I/O interface, refer to section 3.8.3.

3.8.2 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 3.8.3 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 3.8.3 for the source output.
