KOMORI 2 color - showing main motor overload

Hi guys

I am having KOMORI 2 color machine , it is showing main motor overload, upon opening the Inverter (TOYODENKI Inverter VFR1s - 7R522) it shows the following error : MPU RAM ERROR....

Please help how to resolve it

thank you

 

Sorry guys... a small mistake in Inverter model no (TOYODENKI Inverter VF61s - 7R522).... pls help

 

MPU RAM error is usually fatal. But I have seen them successfully reset to factory spec, then Komori spec entered a few times.

 

does it shows the ram error also

 

Hi! Did you ever get to fixing this problem. I'm having the same problem now.
Thanks!

 

Hi sir

Let me know, what is the exactly problem, in order to help you

Blessing

 

Hi! Had this trouble a couple of months back. Sourced manual from ToyoDenki. Fortunately I had a copy of the parameters for the machine. We reset to factory settings the inverter, key in the parameters. Thankfully it's working except for one minor issue with the potentiometer.
