Checked PID 9 shaft coupler and it is very firmly bonded. So the sticky spot noticed from targets last night is probably not a shaft coupler issue. Checked tension on fiber and pulled down by hand to make sure it wasn't fouled up on something. Compared tension to other cobras and it seemed ok. I may have broken it loose from something, was hard to tell.

Power measurements - Connected current probe to the positive wire from driver board

Phone pics:

  1. Driving PID 9 Phi Stage @ .023/2.5 REV
  2. Driving PID 9 both stages @ .04/.023 S1/S2 REV all at 2.5ms interval
  3. PID 31 both stages FWD @ .036/.022 and 2.8ms interval
  4. PID 31 both stages REV @ .04/.024 and 2.8ms interval
  5. PID 9 both stages FWD @ .036/.021 and 2.8ms interval
  6. PID 9 both stages REV @ .04/.023 and 2.8ms interval
  7. PID 9 both stages REV @ .14/.14 and 2.8ms interval
  8. PID 9 both stages FWD @ .14/.14 and 2.8ms interval
  9. PID 31 both stages FWD @ .14/.14 and 2.8ms interval
  10. PID 31 both stages REV @ .14/.14 and 2.8ms interval
  11. PID 31 theta stage @ .04 REV and 2.8ms interval

Videos:

  1. PID 9 both stages fwd/rev ROM @ .14/.14 and 1.4ms interval. 500 step moves
  2. PID 9 & 31 both stages fwd/rev ROM @ .14/.14 and 1.4ms interval. 500 step moves

Target Testing

  • Loaded updated maps from previous run: 2015_09_03_NSTMaps_V02
  • Increased FWD on time on PID 9 PHI to 0.023 from 0.021
  • Saved and exported new DB as 2015_09_03_NSTMaps_V02_d9phi
  • Restarted MSIM
  • Started target script
