Huanyang VFD PID ?
Posted: Sun Aug 06, 2017 10:46 pmLong shot .... err non cnc application.... thought I'd ask if someone has done it or knows how to do it.....
Huanyang VFD PID ?
4-20mA feedback sensor
Motor control application (4 pole, 50hz, 900rpm (~32hz) to ~ 1500rpm (~52hz))
Problem I have is I've set the setpoint on PD159 as 75% [consider as an abitrary number]
I have an adjustable 4-20mA current source and the VFD just basically uses it as a PID target, not the PID feedback signal
Dispite setting PD160 being set to #0, which "should" enable PD159 as the target setpoint.
Any suggestions?
[I've not tried using an AI 0-10v signal in lieu of PD159 and set PD160 to #1, I'll try that tomorrow]
