Is anyone here familiar with the Lenze 8200 VECTOR inverters? I have a used labeler here that has three model E82EV371_2B drives. One of them is not responding to the analog input. The other two work fine.
The input is just a potentiometer. I have tried swapping the pot with no luck. The Minimum Output Frequency (C0010) is set to 0Hz, and the Maximum Output Frequency (C0011) is set to 30Hz, yet the pot will only vary the frequency from 29.1Hz to 30.0Hz. Even with the pot completely disconnected, it runs at 29.1Hz.
I thought someone here might know of some parameter that would affect the analog input (something along the lines of scaling?). I don't see anything like that in the manual, but there are many undefined parameters.
The next chance I get, I'm going to go through all the parameters and compare them to one of the other 'good' drives, but in the meantime, maybe someone will chime in and save me the effort?...
