- Declare local variables L1, L2
- Compute the new open-loop position: C2 * <encoder counts per rev> / <microsteps per rev> = (C2 * EL * 8) / (MS * 200)
- L1=C2*EL*8
- L2=MS*200
- Write the new open-loop position to C1. (C1=L1/L2)
- Set Df=98 (Realigned)
- Return
Drift Check at Positive Closed Position (X8)

Df | Status Description |
|---|---|
-1 | Closed in the negative position |
0 | Open |
1 | Closed in the positive position |
98 | Realigned; slits are in known position but not necessarily open or closed |
99 | Slit status is unknown |
