Vision series analog output tolerances...

Recommended Posts

Is anyone else having issues with the analog output tolerances on the vision controllers?

We are currently using a v350 controller and running a 4-20mA output to a VFD which requires a fairly precise control level. Using the same program on three different controls we have found that the 4-20mA signal varies upwards of 1/2 mA - 1mA making precise control nearly impossible without testing a ton of units. We are well below the 500ohm limits, and we can see these variances with just a meter with or without load. The wiring when installled is 18AWG, shielded and runs approximately 2 feet.

Any thoughts?
