When the reset-to-preset values have been acknowledged, the program will check to see if the resolver
positions need to be homed to a previously set position. This is done through the valid position flags, B3:0/15
for resolver 1 and B3:0/14 for resolver 2. If the valid position flag, B3:0/15, is set, it will perform a home command
for resolver 1. This command will contain the new position data for resolver 1. If the valid position flag, B3:0/14,
is set, it will perform a home command for resolver 2. This command will contain the new position data for
resolver 2. After the resolvers have been homed, a configuration complete flag is set to indicate the unit is
completely configured.
