Nearest Reverse Multiple Spikes

Nearest Reverse Multiple Spikes move the motor reverse to the closest multiple of Factor plus Offset. Put another way:

$NewPosition=Round↓(CurrentMotorPosition/Factor)∗Factor+Offset$

Nearest Reverse Multiple Spikes use the ← icon in the Spike List to indicate that they are a nearest reverse multiple.

Change The Type

To change the type of spike, select the spike in the Spike List and then select nearest reverse multiple from the type dropdown menu.

Changing The Factor

To change the factor double-click in the Factor column and give it a new factor.

Changing The Offset

To change the offset double-click in the Offset column and give it a new offset.

Example

In this example we want to rotate the turntable reverse to the 9 o'clock position (assuming upstage is 12 o'clock and downstage is 6 o'clock). For this we set our factor to 360 degrees (one full revolution) and our offset to 270 degrees (9 o'clock).
