High-Voltage Supplies

• Outputs:– Coronode: 5-8kV (constant current)– Grid: -300 to -800V (constant voltage)– Substrate: 0 to -800V (sweeped to specified value)

Page 4: P10511: Miniaturization of Xerography

Motor Controller

• Two 68-Pin Connectors – Digital I/O for driving Voltage Supplies– Motion I/O to Motor Drive– Provides DAQ functionality

• PCI connection• Requires Driver Software: NI Motion

Page 5: P10511: Miniaturization of Xerography

Motor Drive

• Connects to 68-pin Motion I/O connector on the Controller via an internally-mapped cable

• Default setting of 10 microsteps/step (2000 steps/rev for a 1.8⁰ resolution motor)

• Motor connections are wired in parallel for higher speed, lower torque

Page 6: P10511: Miniaturization of Xerography

Stepper Motors

• S83-93 for Photoreceptor Drive– Continuous spinning requires Limits disabled

• S57-51 for ESV Drive– Limits will confine ESV to cover the range of a P/R

length• 200 steps/rev (1.8⁰ resolution)

System Logic

• Running the System– User will have to input all the data– The system will run in default values– System will run once and stop– Emergency Stop
