Here is my setup:
AB compactlogix PLC
1769HSC card
Automation direct 1024 incremental encoder
AB panelview 1500
104:1 gearbox (I've verified this is correct)
This is a simple mechanical arrangement of a motor and gearbox turning a caster wheel.
106,496 pulses per rev. represents one turn of the caster wheel. (104*1024)
Here is my problem:
If I mark the caster wheel with a reference to locate one turn, my display shows a complete turn that is roughly 10-15 degrees behind where it should be. Each turn gets more and more out of time.
I've ruled out the encoder being bad (replaced with new), the encoder slipping and the caster slipping.
I've had to increase my full rotation encoder count to roughly 118,600 in order for the machine to limp by.
Does anyone have any ideas?
