Installation, Maintenance, Service & Part List Manual
5.11.1.4
CODE 316: Update Software
Insert the USB flash drive that contains the software update and press this service code. New software will
automatically download and the control may need to be shut down if prompted. Follow the instructions on
the screen.
5.11.2
Group B - Machine Set-Up Codes
The following codes are used primarily when setting up a new machine.
5.11.2.1
CODE 122: Calibration Using Offset
Measure your part and compare the actual measurement to the dimension desired. For example, say you
squared a block using a 3” by 3” rectangular frame. When you measure the parts you find the actual
measurements are the following:
•
X dimension = 3.003
•
Y dimension = 2.995
To calculate your offset, do the following:
•
X calibration offset = programmed ÷ actual = 3.000 ÷ 3.003 = 0.9990
•
Y calibration offset = programmed ÷ actual = 3.000 ÷ 2.995 = 1.0017
For Z axis calibration, machine a reference plane and set your DRO Z readout to 0. Use the DRO to position
the head down some number, for example 1.00”. Machine some material away from a corner so it will be
easy to measure the difference between your reference plane and your new plane.
To calculate your offset with a 1.000” difference in position, measure the actual amount machined and
compare it with 1.000”.
For example, if your measurement showed the difference between the reference plane and the machined
plane is 0.985”, calculate the offset:
•
Z calibration offset = DRO ÷ actual = 1.000 ÷ 0.985 = 1.0152
Once you have calculated your values, enter them through Service Code 122.
5.11.2.2
CODE 123: Calibration
See Section 7.1 for a further explanation of this code.
5.11.2.3
CODE 128: Input Backlash Constant
Code 128 allows you to enter the backlash values for each axis. It displays the value after it is entered.
See section 7.2 for more information on this service code.
5.11.2.4
Code 500: XY Ball Lock Offsets
This code defines the locations of the ball locks located on the table, relative to the home position. These
values are set at the factory, but if the X or Y axis motors or ballscrews are disturbed or replaced, the
machine must be re-homed and the ball lock locations MUST be re-located using a .0001” dial indicator;
sweeping in the ball lock receiver. Major changes to the home switches or cams may also require this
service code to be performed.
5.11.2.5
Code 505: Over Travel Limits
When entering this service code, the soft limits will be disabled so as to allow for setup or troubleshooting.
In addition to the DRO, the motor angle for each axis relative to the limit switch can be seen. This is to
ensure that the index pulse for the motor is close to 180° when it hits the home switch. This is done to
obtain maximum reliability when the machine performs its homing routine. Acceptable angles are 180°
±45°. Failure to set this correctly may cause the machine not to home properly which can lead to
problems. See section 6.20 for a procedure.
1.
SOFT LIMIT ON / OFF
– You can choose to toggle the soft limits on or off. They will default to
off when entering this service code, but will always turn back on after exiting.
2.
SET SOFT LIMITS
– This brings up a table that shows the default soft limits. These values
should not have to be changed by the user.
