Dear Sir

There is an inverter (MICROMASTER 440 7.5 KW) and it's worked since 10 years ago. It uses to control the speed of a LIFTER via PROFIBUS with three types of speed. During this time it has been working in standard situation in environment condition without any changes on it.

But from about one month later, the inverter has showed error 070 and stop the LIFTER during working about three or four times a day (from 7 AM to 4 PM). I controlled all sockets and electrical connections, but the problem has still located. I never changed the situations and adjustment.

Please lead me to find the problem.

Could you tell me the cause of the error?

Is the error related to the PROFIBUS MODULE?

Kind Regards
