Manufacturer Specific Objects

0x2201: 32bit User Variables

This object contains 4 volatile variables. Variable1 in addition has BIT15 and BIT14 mapped to the manufacturer specific bits, B15 and B14, on the Statusword (0x6041).

An example of usage would be if the application requires a custom home routine. These bit could be set as a flag to indicate the home routine has been completed. Due to the volatile nature of the variables if a reset occurs on the drive the flag bit would be reset.
