Good evening. I must change a old MM150/3 inverter with Profibus interface with MM440 inverter.
I have install a new Hardwhare with same address and I/O mapping and same telegramm PPO3 like as OLD.
I have follow a indication in MM440 manual (6SE6400-5AK00-0CP0) for parameter profibus : Parameter P700 and P1000 = 6. But motor don' running. Something of you have make a swap from old to new inverter with success ?
Hi, please give some more information:
Have you changed the Profibus address (either by hardware switches on the profibus module, or by using parameter P918) - is there any bus address faults on the Master?
Did you start with a factory defaulted drive and run the quick commissioning only?
If you are using Starter software (Which I strongly recommend) Can you go online and look at the diagnostics. Look at the control word, as some of the older MM's used a slightly different control word layou (From memory, bit 14 or 15 was utilised on early MM's as a direction inhibit)
Check in the old manuals an new manuals to match up the control words.
Double check on the setpoint page that the main setpoint is set to r2050[1] (i.e. word 2 of the telegram.
Double check that P810 = P811 = 0
As a diagnostic for us, you could post the values in the parameters below while you think your drive should be running:
r52
r2050[0]
r2050[1]
Regards,
Graeme
