KYLEB77 Posts: 4 Rating: (0)	Hello, I am having trouble with Tool Life Monitoring on our 840d. It has worked perfectly since the machine was brought online a year ago, but has just stopped about a month ago. I have been browsing through the DOConCD files (FBW.pdf) and found some variables that needed to be checked (shown below). Any suggestions on what I should look at next? First thing I tried was powered everything down and brought it back up, no change. I am fairly new to the Siemens 840d.... Enabling tool life monitoring To implement tool life monitoring, the spindle (toolholder) or spindles which require this type of monitoring must also be specified in channel-specific MD 20320: TOOL_TIME_MONITOR_MASK. This machine data is bit-coded. Example: MD 20320: TOOL_TIME_MONITOR_MASK S Value = 1 Spindle number 1 only S Value = 2 Spindle number 2 only S Value = 3 Spindle numbers 1 and 2 only Refer to Chapter 8 for machine data.
