Contents
Robert Todo
- When U39 is removed - save and send to Linear Tech for failure analysis
- Verify operation of RE40 encoder new motor test stand. Appears to not be working
- Rewire 8-cell A123 battery pack to 7cell.
- programming cable in PCB repair box is bad.
- Build Vclamp8 with NEW PFET and 35w resistor
- Ship 1 Vclamp8 to UPD
CEB todo
- check IW experiment, get code at IW, add to SVN
- get ankle statemachine running
- build ankle
- think about EC30 connectors for maxon
- review DY schematics
- resend code to Matt Raurer
- verify Q15 operation of code on MC
- MC feedforward.
- verify that PSER1C board has GND from USB to target
- current measurement PCB (with Y voltage measure)
- encoder breakout boards
- SG breakout boards
- new WIFI wireless
State / Motor Controller
100-8A (BF2)
- Motor control NOT operational (State operational)
TODO
- diagnose problem
- ??? needs force power on ECO
- needs battery voltage ECO
110-006
- 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
TODO
- replace U39
ECOs
110-007
- 11-26-08 : operational
- 11-26-08 : R102 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 ankle 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
TODO
- install R102
- verify that current filter caps are correct
ECOs
110-008
- 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
TODO
- Diagnose failure
ECOs
110-009 (BF1)
- 11-26-08 : operational, but missing CAP in middle row (C142?)
11-20-08 : Needs the 24 pin flex connect to be replaced. (replaced 11-25-08)- 11-19-08 : Needs battery measurement modification.
- 11-8-08 : has jumper wire to turn self on, but wouldn't boot until IMU attached. After first power, remove IMU and works fine.
TODO
- Replaced missing cap C142?
- needs battery voltage ECO
110-205
- 11-26-08 : needs 3.3V to be applied to get started.
- 11-25-08 : flex connector replaced
TODO
- needs force power on ECO
ECOs
Power Board
100-002
Possibly used to be 110-ENG2
TODO
- needs gate drive ECO
ECOs
- has bypass TVS ECO
110-004
- 11-26-08 : benched tested for 3 days.
- 11-26-08 : has 2.0 ohm gate drive
- 11-26-08 : has 225W TVS on bypass caps.
TODO
- needs gate drive ECO
ECOs
- has bypass TVS ECO
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
TODO
- needs gate drive ECO
ECOs
- has bypass TVS ECO
110-007
- 11-26-08 : operational
TODO
- needs gate drive ECO
ECOs
- has bypass TVS ECO
110-008
- 11-26-08 : is operational, but seems like it might be warm. I=180mA in mode 3, 0 torque. Added schottky and still gets warm (Hot). Upto 280mA depending on motor angle.
TODO
- diagnose large power draw
ECOs
- has bypass TVS ECO
- has gate drive ECO
