LF_TEST_102
This is a reduced stress test.
- 1500 N max thrust using : standard thrust vector file
- belt thrash is only a DC current of 3 amps
- appx 24 cycles per min, not sure why is so slow.
- full amplitude back drive : copley PVT file - ceb_pvt_full_speed.txt
LF_TEST_101
This is a very harsh stress test.
- appx 29 cyc per min
- has belt thrash
- full amplitude back drive : copley PVT file - ceb_pvt_full_speed.txt
- 3000 N max thrust using : standard thrust vector file
LF_TEST_100
Normal thrust force, but no belt thrashing.
- appx 30 cyc per min
- full amplitude back drive : copley PVT file - ceb_pvt_full_speed.txt
- 3000 N max thrust using : standard thrust vector file
