Interpretation of the resulting values displayed:
The values for the encoder displays should be in the range of 3.0000” to 5.0000”.
If the motor encoder and sensor or glass scale reading is not within this value, then the one that is out of
specification may be the problem. If one of the encoders is not reading then it will need to be replaced.
The feedrate should be a minimum of 120 ipm.
If the feedrate is less than 120 ipm and inconsistent in both directions, check the incoming AC voltage and
mechanics of the drive train.
4.9.2.4 CODE 123: Calibration
See Section 5.2.2 for a further explanation of this code.
4.9.2.5 CODE 127 - Set X or Y Backlash Constant
See Section 5.2.2 for a further explanation of this code.
4.9.2.6 CODE 128: Input Backlash Constant
Code 128 allows you to enter the backlash values for each axis. It displays the value after it enters. This code is only
used on machines with motor encoders only.
4.9.2.7 Code 304: Toggles X sensor or glass scale on/off
This service code toggles the X sensor or glass scale on or off. It is used to configure the machine and also is a useful
tool for troubleshooting. Code 313 (configuration file) displays whether the sensors have been turned on or off. The
line labeled secondary feedback explains which sensors or glass scales are turned on. This line can read any one of the
following:
0 = sensors or glass scales turned off
1 = X sensor or glass scale turned on only
2 = Y sensor or glass scale turned on only
3 = both X and Y sensor or glass scale turned on
4.9.2.8 Code 305: Toggles Y sensor or glass scale on/off
This service code toggles the Y sensor or glass scale on or off. See Code 304 for further explanation.
4.9.2.9 Code 321: Reverse Y position sensor direction
This service code reverses the direction of the encoder. It may be needed if sensors or glass scales are mounted on
different sides of the machine.
4.9.2.10 Code 322: Reverse X position sensor direction
This service code reverses the direction of the encoder. It may be needed if sensors or glass scales are mounted on
different sides of the machine.
4.9.2.11 Code 325: Reverse Quill Sensor Direction
This service code reverses the direction of the encoder.
4.9.3 Diagnostic Codes
The following codes are used primarily when diagnosing a problem with the machine. To get to any of these codes go
to Service Codes, press “C” and press the code you wish to view.
4.9.3.1 Code 54: Program Continuous Run
This Code runs a program continuously without
stopping for SET Z or CHECK Z commands. It is helpful in running a
long period to identify an intermittent problem.
1.
Prepare a program as you normally would.
2.

4.9.3.2 Code 81: Keyboard Test
This code is used to check if the keyboard is functioning correctly. It allows you to test each key on the pendant
individually. When you press the keys, the corresponding box for that key will highlight on the screen. The pendant will
also beep, indicating that the key is working correctly. If one of the keys does not work the pendant assembly may
need to be replaced. If none of the keys are working chances are that the computer module will need to be replaced.
