Evening all.
Got a bit of a problem here, process was running fine, 440 fails, new one installed, process not running fine anymore!
I've never had to troubleshoot a 440 drive before so downloaded the manuals and did a search on here and have got this far:
Q --> 440
PZD1 Control word 1, stop H47E, start H47F, reset H4FE
PZD2 Speed set point
PZD3 Not used
PZD4 Control word 2, Manual H0, PID H100
PZD5 P term
PZD6 Not used
PZD7 PV
PZD8 SP
440 starts and stops ok, so Profibus is clearly working but it will not change to PID control when H100 (bit 7 on) sent to PZD4.
Looks like some parameters need to be set in the 440 but I'm struggling to figure out which ones.
Any tips?
