Detailed data
GE DS200DCFBG1B Drive Board
Voltage-controlled oscillator (VCO) circuits on the DCFB board transform input voltages into frequency signals. The nominal output frequency of each VCO is 250 kHz. Depending on the input voltage, the output frequency ranges from 0 to 500 kHz. Through connection 1PL, VCO outputs are transmitted to the SDCC/LDCC board to provide the following feedback:
-SCR bridge ac input voltage
-Output bridge voltage
-Motor voltage (NA)
-Millivolt signals from field shunts
-Millivolt signals from armature shunts
Through connector 1PL, pin 13, the output bridge VCO circuit communicates feedback to the SDCC/LDCC board (1PL- 13). Scaling the voltage provided to the circuit is accomplished using DIP switch SW4. Testpoint TP37 on the SDCC/LDCC board receives a diagnostic signal through 1PL-37 from a frequency-to-voltage reconstruction circuit. An ac-coupled oscilloscope can be used to see the diagnostic bridge voltage signal. Through 1PL-39, the second VCO communicates motor voltage feedback to the SDCC/LDCC board. Scaling the voltage provided to the circuit is accomplished using DIP switch SW5.
