[FONT=Arial, sans-serif]I am having an issue with either the Encoder – an Encoder Products [FONT=Arial TUR, sans-serif]25T-40SG-0500NV1RPP-SMJ-S3[/FONT][FONT=Arial TUR, sans-serif] or the High Speed Counter on a ML 1200.[/FONT][/FONT]
[FONT=Arial TUR, sans-serif][/FONT]
[FONT=Arial TUR, sans-serif]The encoder is installed with Count B on I:0/0, Count A on I:0/1 and the Z reset on I:0/2.[/FONT]
[FONT=Arial TUR, sans-serif]It is a 500 pulse / revolution encoder running at approx 1 second per revolution. Not very fast at all.[/FONT]
[FONT=Arial TUR, sans-serif][/FONT]
[FONT=Arial TUR, sans-serif]The HSC is set to Mode 7. (Count both directions with the reset pulse). The Embedded I/0 Configuration is set so the input filters for Inputs 0 + 1 and 2 + 3 are set to 25 micro seconds.[/FONT]
[FONT=Arial TUR, sans-serif][/FONT]
[FONT=Arial TUR, sans-serif]When I talk to the folks at Encoder Products they act like they never heard of a Micrologix processor before.[/FONT]
[FONT=Arial TUR, sans-serif]I have an earlier set up on a similar machine and had a problem with the Z pulse being high and going low for the reset pulse. They said that I had it wired wrong or something was up with the “Counter” I was using. They did rewire the Encoder for the Z Not signal and it worked. They said that the Open Collector wasn’t as hardy as a Push Pull output, so I ordered this Encoder with the Push Pull out put. Occasionally it works, but it is totally random.[/FONT]
[FONT=Arial, sans-serif]What could I be missing?[/FONT]
