• Wiki Markup
  *Se* \- Pulse Picker mode \[Se\]lect. Refer to Mode List for a complete list of Se modes.

• Sd - Status indicator register. Used for debugging. Refer to Status List for a complete list of statuses.

• Wiki Markup
  *Sw* \- \[Sw\]eep distance. Number of motor steps to equal 11.25 degrees of motion.

• Sr - Encoder sweep distance. Number of encoder steps to equal 11.25 degrees of motion.

• Wiki Markup
  *Dr* \- Encoder \[Dr\]ift, or the difference between the encoder count the predicted encoder position.

• P0 - Center (open) position, in motor steps.
• P1 - Positive closed position, in motor steps, nominally P0+Sw. (Repurposed from standard MCode program.)
• P2 - Negative closed position, in motor steps, nominally P0-Sw.
• N0 - Center (open) position, in encoder counts.
• N1 - Positive closed position, in encoder counts, nominally N0+Sr.
• N2 - Negative closed position, in encoder counts, nominally N0-Sr.
• Ec - Error checking flag. (0=OFF, 1=ON)
• Ns - Pulse Picker MCode version. (Repurposed from standard MCode program.)
• Hb - Heartbeat counter, incremented approx. every 100ms.
• Po - Position counter shadow register (=P or =C1)
• Cs - Encoder counter shadow register (=C2+
• Ud - Drift violation, motor drifting in + direction (0= NO ERROR, 1=VIOLATION)
• Ld - Drift violation, motor drifting in - direction (0=NO ERROR, 1=VIOLATION)
• Df - Motor position flag (see interpretation below)
