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.
