Parameter Description
This parameter applies when the motion encoder is in use with rate conversion.
The parameter declares in an arbitrary length unit the distance traveled between two successive pulses issued by the motion encoder.
Along with LinePitch, it allows for programming the rate converter issuing the line rate in line-scan systems. The LinePitch parameter should be expressed in the same length unit.
The programmed rate conversion ratio is: RateConversionRatio = EncoderPitch/LinePitch.
The resulting downweb line rate is: DownwebLineRate = EncoderRate x RateConversioRatio
The encoder rate at a given time is the frequency of the pulses delivered by the motion encoder while the observed web is moving.
