2. Read micro steps offset.
   
3. Test passes if 125 < offset < 375.

Service Move

Full Step
Micro Step
Mixed Moves
Detect. Move
Roller

Full Step

Activates Movements in full step for 30-60 sec. Verify the right position after all movements.

Micro Step

Activates Movements in micro step for 30-60 sec. Verify the right position after all movements.

Mixed Moves

Activates Movements in full and micro step for 30-60 sec. Verify the right position after all movements.

Detect. Move

Checks that after several movements carriage returns to the same pos.

1. Save current position.
   
2. Move the carriage from H.P. to F.P. 3 times.
   
3. Move to the old saved position.
   
4. Verify that this position is the same like the saved one.

Roller

Checks Roller moving toward Home and End Position.

1. Move Roller to End Position.
   
2. Move Carriage to Home Position.
   
3. Move Roller toward Home Position.
   
4. Verify encoder pulses.
   
5. Verify detector response.
   
6. Move Roller toward End Position.
   
7. Verify encoder pulses.
   
8. Verify detector response.

Feeder

Forward
Reverse

Forward

Checks feeder encoder pulses forward movement.

1. Check that there is not film inside plotter.
   
2. Turn Feeder motor on at forward (clockwise) direction.
   
3. Check relay driver feedback response.
   
4. Check encoder pulses.

Reverse

Checks feeder encoder pulses reverse movement.

1. Check that there is not film inside plotter.
   
2. Turn Feeder motor on at forward (CCW) direction.
   
3. Check relay driver feedback response.
   
4. Check encoder pulses.

Spinner

Motor On/Off
Speed
Spin & Carriage
Stability
Cri PLL Lock
Str PLL Lock

Motor On/Off

Checks Spinner running at 9600 rpm.

1. Turn Spinner On at 9600 rpm. Intensity value from NVM.
   
2. Check Spinner Counter, Encoder and Index clocks.
   
3. Turn Spinner Off.

Speed

Checks Spinner running at NVM defined speed (xx) with NVM defined intensity.

1. Turn Spinner On at xx rpm with it's intensity.
   
2. Check Spinner Counter, Encoder and Index clocks.
   
3. Turn Spinner Off.

Spin & Carriage

Checks Spinner Encoder Clock during the Carriage movement.

1. Turn Spinner On at 6000 rpm and check.
   
2. Move carriage to Feed Position and during the movement measure the Spinner Encoder Clock.
   
3. Move carriage to the Home Position.
   
4. Check the Spinner Encoder Clock is still OK.
   
5. Turn Off the Spinner.

Stability

Checks Spinner speed stability for all NVM defined speed levels.

1. Turn Spinner On at specific speed. Intensity value from NVM.
   
2. Check Spinner Counter, Encoder and Index clocks.
   
3. Delay additional 3 seconds.
   
4. Check that Min, Max, Correlation factor are in range.
   
5. Repeat (1) - (4) for all usual speed levels.
   
6. Turn Spinner Off.

*) Not included in the short batch, because of long running.

Cri PLL Lock

Checks the CRI PLL frequency which is locked on Spinner Encoder.

1. Turn Spinner at 6000 rpm.
   
2. Turn Spinner at 12000 rpm.
   
3. Turn Spinner at 3000 rpm.
   
4. For (1)-(3) check PLL_CK signal at 18, 20, 22 MHz.

Str PLL Lock

Checks the STROBE5 PLL feedback by loading it with different values.
