- - 3 - -
Before installing the HP103:
•
Check to be sure that you have all of the required parts.
•
Familiarize yourself with the parts of the HP103.
•
Check to be sure that the torch lifter motors you are using with
the HP103 are within the acceptable range.
•
Review the instructions for Configuring the Lifter Mechanics.
1.5 CONFIGURING THE LIFTER MECHANICS
Proper configuration of the torch lifter mechanism is an
important factor for establishing the accuracy of your cutting system.
Be sure that:
•
Gear reduction is selected on the torch lifter so that the
maximum suspension speed does not exceed 3000 mm/min (120
IPM). If higher accuracy is required, maximum suspension speed
should be set to 1500 mm/min (60 IPM).
•
Gears, racks and spindles have minimal backlash.
•
Oversizing is avoided. The mass of moving parts, including
armature inertia must be as small as possible. Motors with low
nominal RPM are preferred.
•
Only DC motors with the following ratings are used:
