Command:
aEA
-- Enable Axis for Operation --
Default:
Axis 1 and 2 enabled.
This command will enable operation of servo axis 'a'. If an axis is not enabled for operation,
no system resources will be expended on it. For example, this means that if an axis is going to be
used for it's encoder interface only, it must still be enabled for operation via the EA command,
however, the undedicated encoder interface is always enabled and does not apply here.
Before using the EA command, one should be sure that the Set Servo Speed (SS)
command has been used such that the servo loop time is long enough to service the newly
enabled axis as well as any previously enabled axis'.

Command:
aEGn -- Electronic Gearing Mode --
Argument:
-2 <= n <= 2
Default:
Position Mode
This command causes (slave) servo axis 'a' to begin to move proportionally to (master) servo
axis 'n'. If 'n' is "0" then the electronic gearing mode for axis 'a' will be disabled. If 'n' is positive
then the slave axis will track the master axis' optimal position (or that which is reported by the T O
command). If 'n' is negative then the slave axis will track the master axis' real position (or that which
is reported by the TP command). It is preferable that the EG command only be used when the
target (or slave) axis is not in motion.

Command:
aFEn
-- Find Edge of Coarse Home Input --
Argument:
-2,147,483,647 <= n <= 2,147,483,647
This command is used to initialize servo axis 'a' at a given position. It will remain in effect
until the Home input goes active. At that time, the current position of the servo will be defined as
'n'. This command will neither start nor stop any servo motion. It is up to the user to initiate servo
motion before issuing the command and to stop any motion after the command is completed.
