EHI hdm fmode Gravure Japanese_Newspaper_OEM_Engine Lotem_Quantum Magnus_400 Magnus_800 Magnus_VLF Slave_MCE_Firmware Thermoflex Think_Motion_Controller Trendsetter_400/800 Trendsetter_NEWS Trendsetter_Series_4 Specifies the operating mode of the autofocus servo. Focus modes 0 and 4 are the only modes that should be used during routine imaging. All other focus modes are useful for diagnosing focus problems, however, that the CSE should always leave a customer site with fmode set to 0 or 4. There are currently 8 focus modes. The focus modes operate as follows: Focus mode 0 - uses lens position and optical distance data from the previous swath Focus mode 1 - lens held in a fixed position, using "set head lpos" parameter Focus mode 2 - stationary drum mode, uses lens position and optical distance data from the current swath Focus mode 3 - uses lens position and optical distance data from the current swath Focus mode 4 - uses lens position and optical distance data from the previous swath and the current swath, used on diffusively reflecting plates Focus mode 5 - uses lens position and optical distance data from the previous image, collects no data during the current image Focus mode 6 - does not learn focus, uses lens position and optical distance data from the current swath Focus mode 7 - applies a linear or sinusoidal slope to the focus profile by varying focus offset Note that when plotting in fmode 1 the lens does not track the media, but provided lpos is chosen properly at least part of the plate will be in focus to test imaging without autofocus. When plotting in fmode 1 it is necessary to set a sub scan shift of about 0.5 inches to avoid the error message "unable to learn focus, change focus mode or shift plot". Note that without the drum spinning and PLL on and locked only focus modes 1 and 2 can be used. For mode 2 the shutter must also be open. This parameter is available.
