The application involves winch monitoring of cable payout and inhaul operations. The end user may need to adjust the amount of cable paid out where it is impractical to place the winch in a "zero" position. I'm programming the system with an offset so that the operator thinks the payout is being adjusted. The lack of a counter preset function is not a show stopper.
I would think however that the cFP-QUAD-510 would have the ability to be preset because it would often be used for positioning systems.
I tell you what I really wish; is that the cFP-QUAD-510 had inputs and outputs like the cFP-CTR-50x counters. This way I could use the QUAD for very low frequency measurements. As it is, I have to use a QUAD for quadrature signals and a CTR for velocity measurements simultaneously in the same system. This is an extra expense and hassle.
Thank you for responding.
Will the cFP-CTR-502 handle the Line Driver Outputs from an encoder and be used to calculate the frequency of one line?
I have a similar requirement and have posted about the 510 recently to make sure I understood the limitations of the velocity resolution. Unfortunately the customer already purchased very low PPR encoders. the QUAD-510 probably would have worked great if they went with 2500 PPR or higher encoders, but for some reason they went with 60 PPR before consulting us...
This leads me to looking into alternate methods to get the velocity from their encoder signals - and fequency measurements of the digital signal from one channel is fine for me (no direction changes) - but I am not sure the 5V Line Drive Output from the Encoder is compatible with the Sourcing inputs of the CTR-502. Can anyone shed some light on that?
