Instruction manual

Connection Connection of servo amplifier
3 - 8
Digital output interface DO-1
Via this interface a control lamp, a relay or an photocoupler may be addressed, for example.
Provide a diode (D) for an inductive load, or an inrush current suppressing resistor (R) for a lamp
load. (Permissable current: 40mA, inrush current: 100mA).

CAUTION:
When connecting an inductive load be sure to observe the correct polarity of the
recovery diode D. Connecting it backwards could cause the servo amplifier to be
damaged.
