This chapter covers the AMP parameters that are used in homing the axes.
These parameters are significant for both manual and automatic
axis homing:
Parameter: Page:
Dir. to Move Off Limit Switch 5-10
Home Calibration 5-11
Axis Position after Homing 5-12
Home Speed from Limit Switch 5-14
The following outlines how a typical homing operation functions for
incremental systems. Systems with absolute multiturn encoders (available
on some 1326 servo motors) that are compatible with 9/Series do not
require a homing sequence after initial integration. If you have a system
with a distance--coded marker (DCM) linear feedback device, refer to
page 5-8 for details.
The following procedure applies to revision software 13.x or greater.
Refer to page 5-4 if the software revision of your system is 12.x or
earlier:
1. Set the Mode Select switch to “Manual,” and the Jog Select switch to
“Home” (assuming the Standard MTB Panel is being used).
2. Press the appropriate Axis/Direction button to move the axis in the
direction of the home limit switch. Initial speed for this move can be
selected through the use of the jog speed and feedrate override
switches.
Once the homing sequence is initiated, the jog speed switch has no
effect on the speed of the axis. However, the feedrate override switch
still effects speed.
ATTENTION: Some mechanical switches will turn “OFF” at a
different location when approached from different directions.
In those cases, it is essential that the home limit switch be
approached from the same direction every time the axis is
homed. This can be assured by proper switch positioning, PAL
programming, AMP programming and/or operator instruction.
