I wasn't real sure where to post my question but here it is:
E-stops are used to remove power from a machine in order to stop all hazardous movement. I have an issue in our plant that provides another problem. When an e-stop is actuated, the tandem machines stop at different rates when power is applied. This creates a hazard of breaking the product (wire) between the two machines. Although it would momentarily require the presence of power during an e-stop condition, can I implement a decelleration rate on the machine upstream to keep it from lagging behind and snapping the wire? The estimated e-stop sequence would be modified from appx. 3 seconds (with removal of power, ) to appx. 7 seconds which is close to the rate of the downstream machine. Would this violate any OSHA reg, etc. The intent is to remove any danger from the operator and eliminate product/equipment damage.
