HOMING
A defined Home location is required for all servo-positioning
applications. After initial power up, emergency stop or guard
opened, home position must be found. All motion is relative to
this home position. The Home cycle occurs once after power
is applied to the servo drive in response to the Start push but-
ton being pressed. The cutter head rotates towards the home
sensor at the programmed On-Demand blade speed. After the
home sensor has been found, the cutter head will decelerate
and stop at the specified offset position. This position is then
set to 0.0 degrees at the end of the home sequence. If the
home sensor is not found in one revolution of the cutter head,
the following message is displayed on the operator.
The sensor may be faulty, have a loose connection or be
improperly adjusted. Press any key on the operator to
acknowledge the fault. Disconnect power, fix the problem then
restart the cutter.
After a successful home has been completed, if the cutter is
stopped away from the home position and the power to the
machine is left on, the cutter head position is still known.
When the cutter is restarted, the cutter head will return at the
programmed On-Demand blade speed to the home position.
HOME OFFSET SCREEN
By pressing the soft key located under the word Home on the
Maintenance Screen, the offset for the home position is avail-
able. Additional information on how to access this screen can
be found in the Maintenance Area of the operator display
overview in Appendix E of this manual.
The number shown is the current offset value, i.e. the distance
from position zero. A cursor will appear in the least significant
digit. The user has a choice of ways to adjust this number.
Exit or Prev, If no change is required press Exit or Prev to
return to the Maintenance Area screen.
