Appendix A: Troubleshooting Communication Data Issues
Symptom or Error
PC Receive Data Error
3. Does the CAT5 cable run next to any 3 phase or power cables?
(452)
The Cat5 cable should never be run alongside any 3 phase or power
cables. Make sure the CAT5 cable is run well away from Spindle and
servo motors and any other cables with inductive loads such as coolant
and lube pumps, solenoids.
4. Do all your inductive loads have Quench Arcs installed on them?
Quench arcs are very important and must be installed across the coils of
all relays, solenoids and motors. Quench arcs should be installed as
close as physically possible to the load (coil) itself.
5. Are all firewalls and anti-virus are disabled/uninstalled?
The second most common cause of PC Data Receive Errors are
firewalls and anti-virus programs. These programs intercept and
delay the real-time data transmissions between the MPU11 and the PC.
These delays can accumulate to the point that it triggers this fault.
6. Are Windows Updates or any other auto updaters turned on?
Windows Updates and other auto updaters can bring a PC to it's knees.
Make sure all updaters are turned off.
7. Are there any other network devices attached to the PC?
Very often, network traffic from other network devices can cause a
dramatic decrease in PC and network performance. Remove all other
network devices and connections to the PC, uninstall any hardware
drivers or network utilities associated with network hardware not
associated with the network adapter connected to the MPU11.
8. Does your PC hardware meet the minimum
hardware specs?
The minimum recommended specs of Windows 7/8, a CPU with a single
thread benchmark of 1000 or higher, and 4GB of RAM. The single
thread benchmark referenced can be found here

9. Are any other applications running on the PC?
The minimum hardware requirements specified above take into account
running only the CNC11 software. If you are receiving PC Data Receive
Errors, please terminate any other programs that may be running.
Symptom or Error
Jog Panel
1. Is the optional Jog Panel/Pendant plugged into the MPU11?
Communication In Fault
If the Jog Panel/Pendant is not plugged in to the MPU11, plug it in. Or, if
the system is not utilizing a Jog Panel/Pendant, go into the Control
Configuration Screen and change “Jog Panel Required” to No”. To enter
the “Control Configuration Screen” from the Main Screen press:
F1-Setup->F3-Config (pw=137 enter)->F1-Control
Use the arrow keys to select “Jog Panel Required” and press the
spacebar to toggle the setting to “No”. Power off and restart the control
after changing this setting.
