Hello,

I'm currently working on a proyect where I'm using a MicroMaster440 to controll a motor and I want to use the MM440 PID function.

I want to:
Use digital input 1 (722.0) to start/stop the variator.
Use analog input 1 (0-10VDC) to use as my feedback signal.
My setpoint is 70 (always)

But I can't manage to start the PID, I've gone into the manuals and even my local Siemens support, but they haven't been of much help, so I hope you guys can help me, here is what I do:


P3=1
P10=1
P100=1
P304-335= Motor specs.
P304=440
P305=2.5
P307=0.75
P310=60
P311=1415

P0700=1
P1000=1
P1080=0
P1082=60
P1120=5
P1121=5
P3900=1

P3=3
P700=1
P701=99 (to use input 1 as my start/stop)
P757=0
P758=0
P759=10
P760=100
P2000=60

P910=1

PID
P6=4
P5=2250

P2200=722.0
P2253=2250
P2264=755.0 (use analog input 1 as feedback)
P2240=70 (this is my setpoint)
P2274= Td of the PID
P2280= Kp of the PID
P2285= Ti of the PID
P2292= Lím. Salida PID min.
P2291= Lím. Salida PID máx.


And this is it, but the variator never starts, it does nothing (and I honestly doesn't think something is wrong with it, I know I'm doing someting wrong).


So, please if anyone knows what I'm doing wrong or what should I do, please, help me.


Thanks and best regards.

Thanks a lot, I'll try to implement it tomorrow, hope it works.

The other thing is, have the "Software DriveMonitor", and I tryed to use it with an USB-Serial converter (to connect with it) and also with an MPI cable, but I couldn't communicate with the PLC, I also have the Sinamics MicroMaster Starter software, but I don't know how to use it.

Don't you know where I can find information or a tutorial for this sofwares?

Thanks and best regards.
