This instruction allows you to save the present absolute position to the non-volatile memory. This is useful is you want an operator to visually position your load, and then be able to return to that position later in your program. The PSMCC allows you to save eight different positions.

Even though the positions that the PSMCC has "learned" will still be remembered the next day (because they are stored in non-volatile memory), you will need to "home" the system each time it's powered up. Otherwise, the absolute positions that you've saved don't make any sense.
