Resetting the Servos
For safety reasons, the machine powers up with the servo motors
disengaged. While the servos are disengaged the axes cannot
move under servo power. When hand wheels are connected to the
ball screws of the machine, the axes can be positioned manually if
necessary.
To reset the servos:
If a limit switch disengaged the servos:
Manually reposition the machine inside its normal range of travel
If a miscount occurs:
Press the Find Home soft key to reset the servos and return all
axes to their home position
Find home
You should find home before a program is run, or immediately after
startup. During start up, the Find Home soft key is provided on the
start up screen soft key area.
If the find home step is not performed at initial start up, it can be
initiated at any time during operation.
Press the Datum soft key
Press the Home soft key
Press the Find Home soft key
One axis at a time, each axis (X and then Z) will automatically
move the required distance to find the reference marks and
establish the home position.
The sequence for finding home will depend on the machine. Some
machines may use reference switches, ACU-RITE encoders with
Position-Trac™ (distance-encrypted reference marks), or absolute
encoders; or a combination of these.
Finding home applies to the X and Z axes.
After home has been found, the tool’s position (relative to the most
recent datum set) will be displayed.
NOTICE
Not finding home before moving the machine will risk exceeding
the machine's software travel limits, and possible damage to the
machine, and the system.
Programs will not be allowed to run if the homing
process does not complete successfully.
The Find Home soft key is not available if there is an
error, and the front panel LED indicator is flashing. The
error must be corrected, and then cleared from the
message log. Then homing is allowed. For additional
information, see "Message log", Page 179 for
information on opening the message log and clearing
errors.
