Welcome!

You'll want to read this first: Pulse Picker Presentation 2014-06-26.pptx (UPDATED 2014-06-26 with new "Follower" mode).

Mode Descriptions

Mode 1: Single pulse
Mode 2: Continuous trigger

Mode 1 and 2 should be the same program, as the Seq will generate the pulses to the motor, and open/close operation shouldn't make any difference whether it is 1 or more. The motor sees a trigger and moves.

This mode is accessed by <PV>:RUN_MODE2

Mode 3: The motor opens on a pulse, counts N pulses and closes on the Nth pulse. The pre-trigger and close trigger should be factored in by the upper layer software to determine the proper N value to put into the motor. All the motor does is, open on N=1, count, then close on N=N.

This mode is accessed by <PV>:RUN_MODE3

Mode 1 was programmed like just mode 2 with a User "Trigger" enable/disable, which may or may not be useful for us. Sort of like 2 layers of enabling, versus just 1 for mode2
This mode is accessed by <PV>:RUN_MODE1

Pulse Selector Test/Checkout Procedure (6/10/2013)

X motor calibration

• Found offset from X zero position: 5.8075 mm from + limit
• Offset for X zero position: 5.7332 mm from - limit
• Limits performed as expected, and in place before hardstops

Y motor calibration

• Offset from +Y limit to zero: 15.6689 mm
• Offset from -Y limit to zero: 7.9956 mm
• Limits performed as expected, and in place before hardstops

New Interlock:

Add Y motor interlock, position >= 2 mm above 0 position, no X movement allowed

X-Y interlock stopped working today, need to investigate.
