The state of the digital input is displayed in the MintWorkBench Spy window. The input can be can be configured for different user definablefunctions.DIN0+3k3TLP280DGNDMintVccMotiFlex e100DIN0- 100R 74LVC14197Figure 47 - General purpose digital input circuitWhen the MotiFlex e100 is connected to Mint WorkBench, the digital input can be configuredusing the Digital I/O tool. Alternatively, Mint keywords including RESETINPUT, ERRORINPUT,STOPINPUT, FORWARDLIMITINPUT, REVERSELIMITINPUT, POWERREADYINPUT andHOMEINPUT can be used in the command window. The state of the digital input can be viewedusing the Mint WorkBench Spy window’s Axis tab. See the Mint help file for details.5.3.2.1 Using a digital input as a home switch inputWhen the MotiFlex e100 is being controlled over EPL by a manager node (e.g. NextMove e100),the home switch input must be wired to the MotiFlex e100, not the manager node. This is becausethe manager node only triggers the homing sequence, which is then performed entirely by theMotiFlex e100. It is therefore the MotiFlex e100 which must receive the home switch input signal,otherwise it will not be able to complete its homing routine. Similarly, it is the MotiFlex e100’s ownHOME... keyword parameters that define the homing sequence.197
