8 USING STO FUNCTION

8.4 Detailed explanation of interfaces

Digital output interface DO-1

This is a circuit in which the collector of the output transistor is the output terminal. When the output transistor is turned on, the

current flows to the collector terminal.

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.

(Rated current: 40 mA or less, maximum current: 50 mA or less, inrush current: 100 mA or less) A maximum of 5.2 V voltage

drop occurs in the servo amplifier.

■When outputting each of two STO states by using each TOFB

*1 If the voltage drop (a maximum of 2.6 V) interferes with the relay operation, apply high voltage (a maximum of 26.4 V) from an external

source.

■When outputting two STO states by using one TOFB

*1 If the voltage drop (a maximum of 5.2 V) interferes with the relay operation, apply high voltage (a maximum of 26.4 V) from an external

source.
