MAX COMMAND REFERENCE MANUAL 1-26 1.13. STAND-ALONE COMMANDS The stand-alone mode allows a MAX Motion Controller to run in a completely independent operation mode when powered by a separate +5 VDC power supply and ±12 VDC (for servos). This mode has several commands that can establish links to macros. When set up properly in this mode the controller can scan for a predefined I/O Input bit, until it changes to the specified state Upon sensing that this condition has been met, it will execute the permanent Macro from Nonvolatile flash memory that had been previously associated or linked with this I/O bit and its state. A common application the stand-alone mode is to incorporate the KILL (KL) function. Reference the SXK command. This will allow the user to stop motion of the device. All of these selections are temporary. They can be made permanent by executing the APP command, which assigns the current parameter values as the Power Up defaults. Note: The APP command should be used sparingly as it causes a write to the on board Flash Memory and there is a finite amount of times that it can be re-written to (i.e. less than 1,000,000 times, typical). Application Overview: The setup of the stand-alone mode is performed through the communication interface by the use of the commands. The user would define the required motion and processes and store them in a macro. Then, with the use of the commands below, the execution of the specific macros would be defined. Once all of the setup is completed the controller would be put in the stand-alone mode (SXM1;) and the execution of the macros controlled by the defined input bits. There are no queue requirements for these commands.
