4.6.38. MHOME (direction) (speed)
This command starts the currently active axis homing in the specified direction at the
specified velocity. The home procedure is defined as follows: The axis begins moving in
the specified home direction. When the axis crosses the home limit, it continues moving
into the home limit until encountering the first encoder marker pulse ( or resolver null ),
and set the position register equal to the HOMEOFFSET axis parameter. If it reaches an
end-of-travel limit, it reverses direction. If it reaches a home limit switch, it will go past it,
reverse direction, and come at it
from the specified direction. If another end-of-travel
limit is encountered, a homing fault occurs. The velocity is specified in machine steps per
second. The direction is specified as –1 or 1 for counterclockwise or clockwise motion.
The axis will accelerate and decelerate at the currently selected modes (linear/sinusoidal)
and rates/times.
The HOMEOFFSET axis parameter may be set in user units by first defining the axis type
using the Type axis parameter and entering the home offset into the HomeOffsetInch (or
HomeOffsetDeg for rotary axes) machine parameter. This will overwrite the
HOMEOFFSET axis parameter, setting it to the correct value for the desired offset in
machine steps.
EXAMPLE:
PARMSET A DRIVE 1
; enable the drive!
MHOME -1 2000
; home direction is counter-clockwise,
; move at 2,000 steps per second
4.6.39. MINCREMENTAL (distance) (speed)
This command starts the currently active axis moving the specified incremental distance
at the specified speed. This command will abort any move in progress and begin the new
move from the current position. A move currently executing will immediately take on the
new velocity. The direction is specified as –1 or 1 for counterclockwise or clockwise
motion. The speed is specified in machine counts per second. The axis will accelerate and
decelerate at the currently selected mode (linear/sinusoidal) and rate/time. The specified
drive must be enabled and the axis must not be in the sync mode or a programming error
will occur.
EXAMPLE:
PARMSET A DRIVE 1
; enable the drive!
MINCREMENTAL -10000 2000
; move to -10,000 machine steps, at
; 2,000 steps per second
