Wiring Diagram
The generalized wiring diagram below shows pulse outputs Y0 and Y1 connected to the drive
amplifier inputs of a motion control system.
Interfacing to Drive Inputs
The pulse signals from Y0 and Y1 outputs will typically go to drive input circuits as shown
above. Remember that the DL05’s DC outputs are sinking-only. It will be helpful to locate
equivalent circuit schematics of the drive amplifier. The following diagram shows how to
interface to a sourcing drive input circuit.
The following circuit shows how to interface to a sinking drive input using a pullup resistor.
Please refer to Chapter 2 to learn how to calculate and install Rpullup.
