EHI head bposn 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 setpoint for the beam position servo controller. The beam position sensor outputs two values which are subtracted and normalized. The control loop adjusts the current in the beam position actuator to drive the normalized output to a value equal to the bposn parameter. Changing "bposn" affects the contrast ratio of the head and the stroke cal noise. Generally should not need changing in the field. If however it is not possible to get a good beam balance then it is worthwhile trying to change the bposn by +/- 200 units to see if the noise level improves. The optimal "bposn" could change from the factory setting if some components in the head shift slightly. This parameter is available.
