3. High-Voltage Supplies Outputs: – Coronode: 5-8kV (constant current) – Grid: -300 to -800V (constant voltage) – Substrate: 0 to -800V (sweeped to specified value)

4. 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

5. 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

6. 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)
