Bosch Rexroth Frequency Converter Fe

05/14/2013 5:44 AM

We use the inverter below to drive a cement packer. Unfortunately it stops on its own, or delays to start when given start command. I am not getting a relevant manual to guide in trouble shooting the same. What could be the cause of the problem?

It's difficult to say, as the installation cannot be seen from here. A phone call to the equipment manufacturers' technical helpline will precipitate the arrival of a replacement manual, if indeed it isn't available immediately via their website.

Good luck.

On the website link you just provided, over on the right side is a link named Instructions. It's a user's manual in pdf format.

Without reading it, I would say you've got an intermittent stop signal. This is usually a normally closed contact between the COMMON and STOP inputs. Sometimes, depending on how the unit is configured, these terminals have a jumper connecting them together. That's where I'd focus first.

Don't forget to check the inverter's fault history messages as they may narrow down what the problem is.

How does it appear? Cement dust on the prints? Perhaps (when it worked well before)

relais. potmeter. Clean with dry air under pressure.

you know that those inverterĀ“s have feedback circuitry , so to different loads they have different (or slightly ) responses! and they may stop due to overload, or to a bad program for your application, or so on so on!

they have thousands of operation modes!
