State / Motor Controller

100-8A (BF2)

  • 12-15-08 : force power on ECO & battery voltage ECO
  • 12-14-08 : scan of SC ADCs show that they're out of range.
  • 12-14-08 : applied power, MC is now operational
  • 12-12-08 : MC switching regulator replaced???
  • 12-11-08 : verified that MC switchers have Vsup. Applied SC 3.3V to MC 3.3V, ~80mA flowed, and the MC booted.
  • Motor control NOT operational (State operational)

TODO

  • needs testing

110-006

  • 12-10-08 : bench top offsets (3250, 3200) with power board #110-005
  • 12-04-08 : Installed into PROTO2
  • 12-04-08 : Board ran all night tests Good!
  • 12-04-08 : started Upd_test_pattern_112608a with PB 110-008
  • 12-04-08 : added force power on ECO and verified that power board lights
  • 12-03-08 : U39 has been replaced with LT3470AEDDB#PBF
  • 11-26-08 : NEEDS U39 replaced
  • 11-25-08: Not operational
  • 11-19-08 : traced MC power. Found that 3.3V supply only goes 1V - applied 3.3V from prg adpt and MC booted. Forced R155 high and 5V MC supply worked.
  • 11-19-08 : appears that MC switcher is bad. Apply 3.3V to ISP, SC boots, but MC does not.
  • 11-8-08 : requires external device to hold it on...
  • 10-6-08 : installed in UP#3

ECOs

110-007

  • 12-17-08 : has trouble starting.
  • 12-15-08 : Installed R192 replace C137, C146 with 0.0001uf
  • 12-11-08 : current offsets caused by missing R192. Also verify filter caps - C137, C146 (remove or replace)
  • 12-10-08 : offsets (3254, 22197) mode 7adc reads (2252, 3440)
  • 11-30-08 : 1st current sensor has large offset
  • 11-30-08 : appears that solder on a 1210 cap was making case contact. This was corrected, and tape is being put on the case surface.
  • 11-28-08 : installed into #2, appears to have trouble turning on - staying on. Appears to be caused by rework and raised components shorting to case.
  • 11-28-08 : Ran 36 hrs test with Upd_pcb#110-005
  • 11-26-08 : operational
  • 11-26-08 : R192 missing this is a pull up on the real time clock
  • 11-26-08 : added R141 to GND ECO (force power on)
  • 11-25-08 : Applied power, not operational
  • 11-19-08 : Applied power, seems to run okay.
  • 11-19-08 : Needs 3.3V to poweron status : component gets hot.
  • 10-8-08 : received from UPD - tested - seems to be DOA
  • 10-7-08 : received by UPD
  • 10-6-08 : died in system while using the battery and under high current load - traced to 3.3V motor controller supply not working. Was used with power board that has TVS installed on caps, and external TVS were also used. Died
  • 10-5-08 : installed in UP#3, made battery measurement ECO

ECOs

110-008

  • 12-14-08 : powered and no motor controller LED
  • 12-12-08 : switching regulator replaced??
  • 12-11-08 : verified that MC switchers have Vsup. Applied SC 3.3V to MC 3.3V, ~100mA flowed, and the MC booted.
  • 12-10-08 : MC is unpowered. Need to replace MC 3.3V switcher?
  • 11-26-08 : appears that the motor controller dsPIC is unpowered.
  • 11-19-08 : Rob added GND connection to keep board powered on (either at TP93 or otherside R141)
  • 11-19-08 : Applied 3.3V to ISP header and SC booted.
  • 11-19-08 : IMU #2 connected, push switch and won't power up
  • 10-5-08 : need to evaluate
  • 10-4-08 : Removed from UP#3, as randomly powers on at ~10hz due to noise? possibly damaged due to the pushbutton that WAS attached.
  • 10-1-08 : Modified for auto-off : requires external signal for power on, has MC battery voltage ECO

  • 12-12-08 : robert states that there is mechanical damage to the PCB and some of the encoder decoders.
  • 12-12-08 : still running in morning
  • 12-11-08 : ran Upd_test_pattern_112608a with PB 110-008 overnight
  • 12-11-08 : Added jumper wire from R68 to U16.6. Encoder now works.

Power Board

100-002

  • 12-17-08 : Reset controller when powered. Magic smoke escapes from unknown source.
  • 11-29-08 : Simple verification with SC 110-205, seems operational. 5 mins of Upd_test_pattern_112608a
  • 11-27-08 : Failed during high RPM test. Application of 30V suggests that all the installed TVS devices have failed. PB Led is off, no 12V supply. Bypassed Q2 and 12V supply started. Removed power, and 12V supply still worked.


Possibly used to be 110-ENG2

  • 12-18-08 : u11 also has hot spot
  • 12-17-08 : Applied 5.0V to R8/GND, U9 heated up.
  • 12-17-08 : U3, U10 removed. R8 still has 10 ohms to ground. Cases (Drains) of 6631 fets are correct.
  • 12-14-08 : seriously damaged in airport incident. U3 (ACS712 for battery) destroyed. 12V switcher works, however, 5V MD is overloaded - removed R8 (0 ohm). Also U10 seems to have mechanical damage.

TODO

  • remove U3, then see if 5V supply is loaded, if not then replace R8 (0 ohm)
  • needs gate drive ECO

ECOs

110-005

  • 10-8-08 : installed in upright2; during power platarflexion tests heard noises of instability from motor. reduce motor filter (Q & D) to PWM max of 20k (from 30k). During one test, the motor system seized (making noise) and 17amps was coming from the battery. Afterwards, attempts to energy mode 2/3 caused 1.1amp current draw from power supply

  • 11-29-08 : BROKEN - spins fine in positive direction, but negative is very broken
  • 11-27-08 : appears to have failed turning overnight test. Originally - VBAT_PROT didn't make it to the 12V switcher.
  • 11-26-08 : operational
