Mitsubishi Electric Demo: Flying Shear MR-MQ100 Single-Axis Motion Controller

The following demo illustrates a flying shear / flying cutoff application using the MR-MQ100 Single-Axis Motion Controller from Mitsubishi Electric Automation, Inc. The servo motor follows feedback from an incremental encoder with a mark sensor that is used for high-speed registration.

i use fx5u plc to read value of encoder A/B. I used this function with fx3u is OK. but when i use with fx5u then not yet. maybe help me?

Hello sir, I am using FX5U PLC for flying Shearing application in which main drive is siemens G120 which controls the movement of sheet to be cut, one encoder is fixed with rollers and pressed with force on sheet so that it will rotate when sheet moves. encoder feedback is given to PLC. For shear control we have Yaskawa servo drive which is controlled by PLC using pulse output. we are reading encoder feedback for speed and length calculation and according to that we are giving pulse output to servo. but its not working properly, whenever we change speed we get 20mm length variation and on constant speed we get 3-4 mm. but we require 1 mm max variation. what can we do in PLC. our main encoder is of 2000ppr. we have contacted with local support but no resolution found. thanks

Hello, where this application industrial?
