If the stage has full mapping this command will enable it. User must use SIS
command to send the stage to the limits and establish the absolute
coordinate system.
When a new stage is first attached to the controller or a RESET command
or software update has occurred, it should be noted that loading the full
mapping from the stage to controller takes about 20 seconds, the
controller will be unresponsive until this data is loaded.
N
N=0 Ok
N=E,44 SIS not done
N=E,51 stage not mapped
NOTE: if a stage leaves production with encoders fitted then the
correction only applies to that stage when the encoders are enabled.
Turning encoders off, or adding encoders retrospectively to a non-
encoded stage will invalidate the stated correction capabilities of the stage
