Savable in Sequence commands are saved when they are defined in a sequence (see XT
command). Savable in Sequence commands can be stored in system memory (nonvolatile)
and retained when power is removed from the system. A command that is Never Saved is
executed without being saved into the system’s permanent memory . Automatically Saved
commands are automatically saved into memory upon execution.

The Acceleration command specifies the rotary acceleration rate to be used for the next Go
(G) command. The acceleration remains set until you change it. You do not need to reissue
this command for subsequent Go (G) commands. Accelerations outside the valid range
cause the acceleration to remain at the previous valid A setting.
If the Acceleration command is entered with only a device address (1A), the controller will
respond with the current acceleration value. If a move is commanded without specifying an
acceleration rate, the previously commanded acceleration rate will be used. Acceleration
cannot be changed on the fly. The minimum acceleration is
Min Accel = Encoder resolution (ER command) x .00465
