OSD—Enable Z Channel for home uses the Z channel of the encoder, in conjunction with a
home switch, to determine the final home position. The Z channel is a more accurate home
position than the edge of a switch.
OSH—Reference edge of home switch allows either edge of the home switch to be used as
the final edge position.
The Controller will reverse direction if an end-of-travel limit is activated while searching
for home. However, if a second end-of-travel limit is encountered in the new direction, the
Go Home procedure will stop and the operation will be aborted. The Homing Status (RC)
command will indicate if the homing operation was successful.
The Go Home command will use acceleration set by the A command. The Go Home
velocity will not affect the standard velocity (V) value.

The motor moves CCW at 2 revs/sec and looks for the Home Limit input to
go active.
Since the motor is turning CCW, it will see the CW edge of the limit first. It will decelerate
to a stop and turn at 0.1 rev/sec in the CW direction until it detects the Z channel.

This command allows you to delete the last character that you entered. The ^H command
will not prevent execution of an immediate command. A new character may be entered at
that position to replace the existing character. (^H indicates that the Ctrl key is held down
when the H key is pressed.) This command prompts the controller to backup one character
in the command buffer, regardless of what appears on the terminal. On some terminals, the
Ctrl and the left arrow (<—) keys produce the same character.
This command will not delete characters beyond the last delimiter issued. Pressing the
delete key will not delete the previous character.
