Hi, I have a question regarding an analog output that I just cannot understand, if anyone can please help out I greatly appreciate.
I’m replacing this drive(UNIdrive 1405) with a PF 7020ADO11F0AYNANC0 and need to set up an analog output as reference back to the PLC the same way its set up in the UNIdrive 1405, question is I don’t know what output the drive represents at terminal 9, is it output frequency, output amps etc. The Unidrive also has a digital input Preset Speed 1 that is set to 65Hz but when I toggle this input the 0-20mA output current value is unaffected, this would in fact indicate that terminal 9 is not set up for output frequency.
Looking at the setup I think there is some scaling done in the drive of the analog input against the High and low frequency Parameters #1.06 and #1.07 and that’s what would represent the analog output but I’m baffled by this. Here is the setup.
UNIDRIVE 1405
Parameter
Analog input 0-20mA to terminal 5+ speed reference
Analog Output on terminal 9 feedback
Parameter #1.06 Max Frequency 71.0 Hz
Parameter #1.07 Min Frequency 12 Hz
Parameter #7.19 (Source) Parameter #1.36
Parameter #7.20 (Scaling) 1.000
Parameter #7.21 (Output) 0-20mA
Now Parameter #7.19 is linked to Parameter #1.36 Analog reference 1,I’m not quite sure what that parameter does except for scaling against the Min. Max. frequency of parameters #1.06 and # 1.07.
Please help, thank you in advance.
Par #1.08 is set to 0
Need to accomplish the same result in PF 70
Here is also a screenshot from the PLC side of the analog Input to PLC
