SECTION FOUR - COMPONENT DESCRIPTION AND SPECIFICATION 4.3 4.1.2.3. Shunt Regulator Circuit Rapid motor deceleration or an overhauling load creates a situation in which energy is regenerated back into the high voltage power supply. This regenerative energy will charge the power supply bus capacitors. To prevent capacitor over voltage a shunt regulator circuit senses when the bus voltage exceeds the regen cut-in voltage and via a regen transistor, switches a regen resistor across the d-c bus,

4.4 SECTION FOUR - COMPONENT DESCRIPTION AND SPECIFICATION 4.1.2.4. Monitoring and Fault Logic There are two fault outputs in the supply. The "Customer Fault Output" is relay K2 (4C1) capable of sinking or sourcing 1 amp and withstanding up to 75V. It is "closed" during normal operation and will be "open" to indicate a fault. The faults that are detected are Thermal Fault, Loss of Phase, Bus Over voltage, Regen Fuse Blown and Soft start. Note that a fault indication in the power supply wil

4.8 SECTION FOUR - COMPONENT DESCRIPTION AND SPECIFICATION 4.2.2.3. Analog to Digital Section The analog command input has an input voltage level of +/- 10VDC. It is brought in to a differential amplifier. The choice is available in software to either use this command signal unfiltered or to use a low pass filter on the command. The filter has a -3dB point of 1KHz and an inband time delay of 360µsec. The command signals are converted by the A/D converter, a 12 bit converter. The resolver exc

4.12 SECTION FOUR - COMPONENT DESCRIPTION AND SPECIFICATION The Built In Test (BIT) output of the R/D converter is monitored. Logic 0 for BIT condition indicates ±100 LSBs of error. Causes of BIT error are loss of signal inputs or loss of resolver reference. When this occurs, the Encoder Simulator outputs will go to a known state. Figure 4-7 is a block diagram of the Encoder Simulation option card. 4.4.1.1. A and B Outputs The A and B outputs are in quadrature, i.e. B will lead A by 90° when t

SECTION FOUR - COMPONENT DESCRIPTION AND SPECIFICATION 4.13 4.4.1.2. Marker Pulse The MARKER, or INDEX pulse, is used to indicate a reference point within one mechanical revolution of the motor shaft. NOTE The marker pulse is not referenced to the key of the motor shaft or housing. The pulse is set at an arbitrary position that is determined by the resolver adjustment setting used for motor commutation. This is a factory setting and not user adjustable. The electrical width of the MARKER pulse
