Page 19: Theory Of Operation
Theory of Operation Block Diagram The block diagram shows the basic design of the 8712. The microprocessor reads the input mode bits when power is turned on and selects the input interface. It also flashes the firmware version number on the internal red LFAULT indicator. -
Page 20: Input Mode Control Bits
Theory of Operation When LIDLE is pulled low, the microprocessor shuts down the power supply and stops generating Picomotor drive pulses. The response to this input is rapid enough to prevent the generation of more than one pico pulse after LIDLE goes low. -
Page 21: Linear Voltage Input
Theory of Operation Quadrature-Mode Operation In normal operation, the drive pulse rate is 4 times the frequency of the A- phase and B-phase waveforms. Do not exceed the A/B-phase frequency of 500 Hz. The Picomotor drive pulse rate cannot go over 2kHz. A perfect quadrature phase relationship between A-phase and B-phase will generate evenly spaced Picomotor drive pulses. -
Page 22: Bang-Bang Voltage Input
Theory of Operation Detailed View of Pulse Rate vs. Input Voltage around the dead-band for Linear Voltage Input Mode Voltages between 78-mV steps will cause the pulse frequency to switch back and forth between two pulse frequencies. Connect ANALOG IN+ to a low impedance voltage source. -
Page 23: Power Supply
Theory of Operation Green and red LEDs can be seen through these holes. Status Indicators position The red LED is tied to LFAULT (pin 15). It will flash the firmware revision number when the unit is turning on, and will also turn on if the output amplifier temperature approaches the design limit.(You can also monitor the temperature using the TEMP MONITOR, pin 21. -
Page 24: Power Connections
Theory of Operation • Over-voltage protection: If the power input voltage exceeds 16.7 to 18.5 V, a transient voltage suppressor (TVS) shunts the power input to ground. The internal 2-A fuse will then open. The TVS will also shunt the power input to ground if an internal fault shorts any high voltage to the power input. -
Page 25: Control Interface
Theory of Operation concern for ground loops associated with the control wiring. +V IN and SYS GROUND should be routed one on top of the other (and with at least 0.5"- wide traces). You can use ground/power planes to route +V IN and SYS GROUND. Use ground/power planes with caution: continuous planes can allow coupling between the 8712 power and neighboring circuits. -
Page 26: Output Connections
Theory of Operation connect DGROUND to SYSTEM GROUND at the 8712 unless you are just trying to make a simple hook-up to test operation of the 8712. Output Connections PULSE OUTPUT and PULSE RETURN connect the 8712 to the external Picomotor connector. -
