– Motor Control (Select)
The Motor Control window provides a numeric window where the user can type in the desired motor position. After
pressing Enter, the move is initiated. The motors can either be jogged in the positive or negative direction by fixed
increments.
For the left FHB, the user is also given a checkbox option to apply the current position to the FHB offset. And for
the Cleave Blade motor, the user can apply the position to the Pre-Cleave Advance parameter.
7.5.2. Auto Parameter
Auto Parameter will generate a basic set of suggested theoretical values based on Fiber Diameter (and if required,
Desired Cleave Angle). Touching any parameter in the list will allow fast access to modify that parameter.
Note that the default value for the Fiber Modu
lus is its Young’s Modulus of Elasticity - typically 28 for SMF28.
However for softer glass, 28 will be too high, and you should look up the modulus of rigidity. A smaller number
should also be used for photonic crystal fiber (PCF). The modulus of rigidity of silica glass varies from 19 to 31 GPa.
