We have a Sodick EDM model A7C with MARK X1B contol. The machine was kept idle for few months. When it is made on now, it is booting ok. But, when trying to do zero return, the axis does not move and gives various error messages like Heat stop by overload press ack key, Touching limit switch on stroke end (over travel ) press ACK, etc. When I press ACK key, the error does not go. I want to know, whether this problem can be due to parameter loss. Can anybody provide parameter settings for this control ?
